本文介绍了使用 PyInstaller 打包后 PySide2 应用程序中的路径错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试使用以下结构打包 PySide2 测试应用程序:

<预><代码>.├── main.py├── main.spec└── 精灵UI├── 10.toolBoxBtns.ui├── 11.toolBoxShrCt.ui├── 12.propertyBox.ui├── 13.printing.ui├── 14.settings.ui├── 15.coclusion.ui├── 1.welcomePage.ui├── 2.graphicsScene.ui├── 3.graphicsSceneText.ui├── 4.textDialog.ui├── 5.codeDialog.ui├── 6.graphicsSceneBox.ui├── 7.graphicsScenePixmap.ui├── 8.graphicsSceneShrCt.ui├── 9.toolbox.ui└── 精灵.py

当我尝试运行可执行文件时出现此错误:

<块引用>

FileNotFoundError: No such file or directory:'/home/artem/Desktop/testUI/dist/main/wizardUI'

这是我的 Wizard.py 文件

from PySide2 import QtCore, QtWidgets从 PySide2.QtUiTools 导入 QUiLoader导入操作系统类导师向导(QtWidgets.QWizard):""" 包含介绍教程 """def __init__(self, parent=None):super(tutorWizard, self).__init__(parent)self.setWindowTitle("介绍教程")pages = self.findPages()self.initPages(页数)def findPages(self):ui_files = []cnt = 1current_dir = os.path.dirname(os.path.realpath(__file__))而 len(ui_files) != 15:对于 os.listdir(current_dir) 中的文件:如果 file.startswith("{}.".format(cnt)):ui_files.append(os.path.join(current_dir, file))cnt += 1返回 ui_filesdef initPages(self, files):加载器 = QUiLoader()对于我在文件中:文件 = QtCore.QFile(str(i))file.open(QtCore.QFile.ReadOnly)文件.重置()页面 = loader.load(file)文件.close()self.addPage(页面)

main.py 是:

 from PySide2.QtWidgets import QApplication从wizardUI.wizard 导入tutorWizard导入系统app = QApplication(sys.argv)窗口 = 导师向导()window.show()sys.exit(app.exec_())

和 .spec 文件是:

# -*- mode: python ;编码:utf-8 -*-block_cipher = 无a = Analysis(['main.py'],pathex=['/home/artem/Desktop/testUI'],二进制文件=[],数据=[],hiddenimports=['PySide2.QtXml'],钩子路径=[],runtime_hooks=[],排除=[]，win_no_prefer_redirects=假，win_private_assemblies=假，密码=块密码，noarchive=假)pyz = PYZ(a.pure, a.zipped_data,密码=block_cipher)exe = EXE(pyz,a. 脚本，[],exclude_binaries=真，名称='主要'，调试=假，bootloader_ignore_signals=假，条=假，upx=真，控制台=真)科尔 = 收集(exe，a.二进制文件，a.zip 文件，a.数据，条=假，upx=真，upx_exclude=[],名称='主要')a.datas += Tree('/home/artem/Desktop/testUI/wizardUI')

有没有办法在 wizard.py 中不用修改 current_dir 变量来解决这个错误?

解决方案

你的代码有以下问题:

  • 您在 COLLECT 之后将 Tree() 添加到 a.datas 中，因此它不会在编译中使用，您必须在此之前添加.

  • 您不能再使用 __file__ 来获取目录路径，而必须使用 sys._MEIPASS.

我还将进行以下改进:

  • 为了使 .spec 可移植，我将使用 SPECPATH 变量.
  • 我添加了第二个参数wizardUI"以使用 .ui 创建字典，我还排除了 Wizard.py.

综合以上，解决方案如下:

ma​​in.py

 from PySide2.QtWidgets import QApplication从wizardUI.wizard 导入tutorWizard导入系统如果 __name__ == "__main__":app = QApplication(sys.argv)窗口 = 导师向导()window.show()sys.exit(app.exec_())

wizard.py

导入操作系统导入系统从 PySide2 导入 QtCore、QtWidgets、QtUiTools# https://stackoverflow.com/a/42615559/6622587如果 getattr(sys, 'frozen', False):# 如果应用程序作为一个包运行，pyInstaller 引导加载程序# 通过一个标志frozen=True 扩展sys 模块并设置应用程序# 进入变量 _MEIPASS' 的路径.current_dir = os.path.join(sys._MEIPASS, "wizardUI")别的:current_dir = os.path.dirname(os.path.abspath(__file__))类导师向导(QtWidgets.QWizard):"""包含介绍教程"""def __init__(self, parent=None):super(tutorWizard, self).__init__(parent)self.setWindowTitle("介绍教程")pages = self.findPages()self.initPages(页数)def findPages(self):ui_files = []cnt = 1而 len(ui_files) <15:对于 os.listdir(current_dir) 中的文件:如果 file.startswith("{}.".format(cnt)):ui_files.append(os.path.join(current_dir, file))cnt += 1返回 ui_filesdef initPages(self, files):loader = QtUiTools.QUiLoader()对于我在文件中:文件 = QtCore.QFile(str(i))如果 file.open(QtCore.QFile.ReadOnly):页面 = loader.load(file)self.addPage(页面)

ma​​in.spec

# -*- 模式:python ;编码:utf-8 -*-# https://stackoverflow.com/a/50402636/6622587导入操作系统spec_root = os.path.abspath(SPECPATH)block_cipher = 无a = Analysis(['main.py'],pathex=[spec_root],二进制文件=[],数据=[],hiddenimports=['PySide2.QtXml', 'packaging.specifiers', 'packaging.requirements'],钩子路径=[],runtime_hooks=[],排除=[]，win_no_prefer_redirects=假，win_private_assemblies=假，密码=块密码，noarchive=假)pyz = PYZ(a.pure, a.zipped_data,密码=block_cipher)exe = EXE(pyz,a. 脚本，[],exclude_binaries=真，名称='主要'，调试=假，bootloader_ignore_signals=假，条=假，upx=真，控制台=真)a.datas += Tree(os.path.join(spec_root, 'wizardUI'), 'wizardUI', excludes=["*.py"])科尔 = 收集(exe，a.二进制文件，a.zip 文件，a.数据，条=假，upx=真，upx_exclude=[],名称='主要')

<小时>

另一种选择是使用 Qt Resource 而不是数据.

resource.qrc

<qresource prefix="/"><file>wizardUI/1.welcomePage.ui</file><file>wizardUI/2.graphicsScene.ui</file><file>wizardUI/3.graphicsSceneText.ui</file><file>wizardUI/4.textDialog.ui</file><file>wizardUI/5.codeDialog.ui</file><file>wizardUI/6.graphicsSceneBox.ui</file><file>wizardUI/7.graphicsScenePixmap.ui</file><file>wizardUI/8.graphicsSceneShrCt.ui</file><file>wizardUI/9.toolbox.ui</file><file>wizardUI/10.toolBoxBtns.ui</file><file>wizardUI/11.toolBoxShrCt.ui</file><file>wizardUI/12.propertyBox.ui</file><file>wizardUI/13.printing.ui</file><file>wizardUI/14.settings.ui</file><file>wizardUI/15.coclusion.ui</file></qresource></RCC>

然后使用 pyside2-rcc 将其转换为 .py:

pyside2-rcc resource.qrc -o resource_rc.py

然后你必须修改脚本:

ma​​in.py

 from PySide2.QtWidgets import QApplication从wizardUI.wizard 导入tutorWizard导入系统导入资源_rc如果 __name__ == "__main__":app = QApplication(sys.argv)窗口 = 导师向导()window.show()sys.exit(app.exec_())

wizard.py

from PySide2 import QtCore, QtWidgets, QtUiTools类导师向导(QtWidgets.QWizard):""" 包含介绍教程 """def __init__(self, parent=None):super(tutorWizard, self).__init__(parent)self.setWindowTitle("介绍教程")pages = self.findPages()self.initPages(页数)def findPages(self):ui_files = []cnt = 1而 len(ui_files) <15:it = QtCore.QDirIterator(":/wizardUI")而 it.hasNext():文件名 = it.next()name = QtCore.QFileInfo(filename).fileName()如果 name.startswith("{}.".format(cnt)):ui_files.append(文件名)cnt += 1返回 ui_filesdef initPages(self, files):loader = QtUiTools.QUiLoader()对于我在文件中:文件 = QtCore.QFile(str(i))如果 file.open(QtCore.QFile.ReadOnly):页面 = loader.load(file)self.addPage(页面)

最后你的项目结构如下:

├── main.py├── main.spec├──资源.qrc├── resource_rc.py└── 精灵UI├── 10.toolBoxBtns.ui├── 11.toolBoxShrCt.ui├── 12.propertyBox.ui├── 13.printing.ui├── 14.settings.ui├── 15.coclusion.ui├── 1.welcomePage.ui├── 2.graphicsScene.ui├── 3.graphicsSceneText.ui├── 4.textDialog.ui├── 5.codeDialog.ui├── 6.graphicsSceneBox.ui├── 7.graphicsScenePixmap.ui├── 8.graphicsSceneShrCt.ui├── 9.toolbox.ui└── 精灵.py

<小时>

这两种解决方案都可以在此处

I'm trying to package a PySide2 test application with the following structure:

When I try to run an executable I get this error:

FileNotFoundError: No such file or directory:'/home/artem/Desktop/testUI/dist/main/wizardUI'

Here's my wizard.py file

from PySide2 import QtCore, QtWidgets
from PySide2.QtUiTools import QUiLoader
import os


class tutorWizard(QtWidgets.QWizard):
    """ Contains introduction tutorial """
    def __init__(self, parent=None):
        super(tutorWizard, self).__init__(parent)


        self.setWindowTitle("Introduction tutorial")
        pages = self.findPages()
        self.initPages(pages)

    def findPages(self):
        ui_files = []
        cnt = 1
        current_dir = os.path.dirname(os.path.realpath(__file__))
        while len(ui_files) != 15:
            for file in os.listdir(current_dir):
                if file.startswith("{}.".format(cnt)):
                    ui_files.append(os.path.join(current_dir, file))
                    cnt += 1
        return ui_files

    def initPages(self, files):
        loader = QUiLoader()
        for i in files:
            file = QtCore.QFile(str(i))
            file.open(QtCore.QFile.ReadOnly)

            file.reset()
            page = loader.load(file)

            file.close()

            self.addPage(page)

main.py is:

from PySide2.QtWidgets import QApplication
from wizardUI.wizard import tutorWizard
import sys


app = QApplication(sys.argv)
window = tutorWizard()
window.show()
sys.exit(app.exec_())

and .spec file is:

# -*- mode: python ; coding: utf-8 -*-

block_cipher = None


a = Analysis(['main.py'],
             pathex=['/home/artem/Desktop/testUI'],
             binaries=[],
             datas=[],
             hiddenimports=['PySide2.QtXml'],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=True,
          name='main',
          debug=False,
          bootloader_ignore_signals=False,

coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=True,
               upx_exclude=[],
               name='main')

a.datas += Tree('/home/artem/Desktop/testUI/wizardUI')

Is there any way to solve this error without changig current_dir variable in wizard.py ?

解决方案

Your code has the following problems:

  • You are adding the Tree() to a.datas after COLLECT so it will not be used in the compilation, you have to add it before.

  • You can no longer use __file__ to get the directory path, instead you must use sys._MEIPASS.

I will also give the following improvements:

  • For the .spec to be portable, I will use the SPECPATH variable.
  • I have added as a second parameter "wizardUI" to create a dictionary with the .ui, I have also excluded wizard.py.

Considering the above, the solution is as follows:

main.py

from PySide2.QtWidgets import QApplication
from wizardUI.wizard import tutorWizard
import sys


if __name__ == "__main__":

    app = QApplication(sys.argv)
    window = tutorWizard()
    window.show()
    sys.exit(app.exec_())

wizard.py

import os
import sys

from PySide2 import QtCore, QtWidgets, QtUiTools

# https://stackoverflow.com/a/42615559/6622587
if getattr(sys, 'frozen', False):
    # If the application is run as a bundle, the pyInstaller bootloader
    # extends the sys module by a flag frozen=True and sets the app 
    # path into variable _MEIPASS'.
    current_dir = os.path.join(sys._MEIPASS, "wizardUI")
else:
    current_dir = os.path.dirname(os.path.abspath(__file__))


class tutorWizard(QtWidgets.QWizard):
    """ Contains introduction tutorial """

    def __init__(self, parent=None):
        super(tutorWizard, self).__init__(parent)

        self.setWindowTitle("Introduction tutorial")
        pages = self.findPages()
        self.initPages(pages)

    def findPages(self):
        ui_files = []
        cnt = 1
        while len(ui_files) < 15:
            for file in os.listdir(current_dir):
                if file.startswith("{}.".format(cnt)):
                    ui_files.append(os.path.join(current_dir, file))
                    cnt += 1
        return ui_files

    def initPages(self, files):
        loader = QtUiTools.QUiLoader()
        for i in files:
            file = QtCore.QFile(str(i))
            if file.open(QtCore.QFile.ReadOnly):
                page = loader.load(file)
                self.addPage(page)

main.spec

# -*- mode: python ; coding: utf-8 -*-

# https://stackoverflow.com/a/50402636/6622587
import os
spec_root = os.path.abspath(SPECPATH)

block_cipher = None

a = Analysis(['main.py'],
             pathex=[spec_root],
             binaries=[],
             datas=[],
             hiddenimports=['PySide2.QtXml', 'packaging.specifiers', 'packaging.requirements'],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=True,
          name='main',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          console=True )

a.datas += Tree(os.path.join(spec_root, 'wizardUI'), 'wizardUI', excludes=["*.py"])

coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=True,
               upx_exclude=[],
               name='main')

Another option is to use Qt Resource instead of data.

resource.qrc

<RCC>
  <qresource prefix="/">
    <file>wizardUI/1.welcomePage.ui</file>
    <file>wizardUI/2.graphicsScene.ui</file>
    <file>wizardUI/3.graphicsSceneText.ui</file>
    <file>wizardUI/4.textDialog.ui</file>
    <file>wizardUI/5.codeDialog.ui</file>
    <file>wizardUI/6.graphicsSceneBox.ui</file>
    <file>wizardUI/7.graphicsScenePixmap.ui</file>
    <file>wizardUI/8.graphicsSceneShrCt.ui</file>
    <file>wizardUI/9.toolbox.ui</file>
    <file>wizardUI/10.toolBoxBtns.ui</file>
    <file>wizardUI/11.toolBoxShrCt.ui</file>
    <file>wizardUI/12.propertyBox.ui</file>
    <file>wizardUI/13.printing.ui</file>
    <file>wizardUI/14.settings.ui</file>
    <file>wizardUI/15.coclusion.ui</file>
  </qresource>
</RCC>

Then convert it to .py using pyside2-rcc:

pyside2-rcc resource.qrc -o resource_rc.py

Then you have to modify the scripts:

main.py

from PySide2.QtWidgets import QApplication
from wizardUI.wizard import tutorWizard
import sys

import resource_rc

if __name__ == "__main__":

    app = QApplication(sys.argv)
    window = tutorWizard()
    window.show()
    sys.exit(app.exec_())

wizard.py

from PySide2 import QtCore, QtWidgets, QtUiTools


class tutorWizard(QtWidgets.QWizard):
    """ Contains introduction tutorial """

    def __init__(self, parent=None):
        super(tutorWizard, self).__init__(parent)

        self.setWindowTitle("Introduction tutorial")
        pages = self.findPages()
        self.initPages(pages)

    def findPages(self):
        ui_files = []
        cnt = 1
        while len(ui_files) < 15:
            it = QtCore.QDirIterator(":/wizardUI")
            while it.hasNext():
                filename = it.next()
                name = QtCore.QFileInfo(filename).fileName()
                if name.startswith("{}.".format(cnt)):
                    ui_files.append(filename)
                    cnt += 1                    
        return ui_files

    def initPages(self, files):
        loader = QtUiTools.QUiLoader()
        for i in files:
            file = QtCore.QFile(str(i))
            if file.open(QtCore.QFile.ReadOnly):
                page = loader.load(file)
                self.addPage(page)

And finally the structure of your project is as follows:

├── main.py
├── main.spec
├── resource.qrc
├── resource_rc.py
└── wizardUI
    ├── 10.toolBoxBtns.ui
    ├── 11.toolBoxShrCt.ui
    ├── 12.propertyBox.ui
    ├── 13.printing.ui
    ├── 14.settings.ui
    ├── 15.coclusion.ui
    ├── 1.welcomePage.ui
    ├── 2.graphicsScene.ui
    ├── 3.graphicsSceneText.ui
    ├── 4.textDialog.ui
    ├── 5.codeDialog.ui
    ├── 6.graphicsSceneBox.ui
    ├── 7.graphicsScenePixmap.ui
    ├── 8.graphicsSceneShrCt.ui
    ├── 9.toolbox.ui
    └── wizard.py
