使用 pyinstaller 编译为 .exe 后，PyQt5 应用程序中缺少图标 [英] Icons missing from PyQt5 app after compiling to .exe using pyinstaller

问题描述

已解决 - 作为答案发布的解决方案，感谢大家的帮助.

使用PyQt5 将我的python 应用程序编译为可执行文件后，GUI 中包含的图标被删除/不显示.特别是 QIcon 实例添加到我的 Window(QMainWindow) 类使用 self.setWindowIcon(QtGui.QIcon(fpath)) 和一个 QPixmap(f2path) 通过 label.setPixmap(myPixmap) 嵌入到 QLabel 中.

After compiling my python application using PyQt5 to an executable file, the icons contained in my GUI are removed / not displayed. Specifically QIcon instances added to my Window(QMainWindow) class using self.setWindowIcon(QtGui.QIcon(fpath)) and a QPixmap(f2path) embedded in a QLabel via label.setPixmap(myPixmap).

我尝试在此论坛上搜索可能的解决方案，但找不到解决问题的线程.我尝试按照此处的建议设置绝对文件路径 将数据文件与PyInstaller (--onefile) 和这里 pyinstaller 中缺少按钮图标

I have tried to search on this forum for possible solutions but couldn't find a problem solving thread. I've tried to set the absolute filepath as recommended here Bundling data files with PyInstaller (--onefile) and here Missing button icons in pyinstaller

不知道从哪里开始检查问题，使用 pyinstaller 编译时没有错误，并且它作为 python 脚本运行良好.

No idea where to start examining problems, there are no errors when compiling with pyinstaller and it runs fine as a python script.

pyinstaller -w -F MY_GUI.py

提前致谢！

示例:

import sys
import os

def resource_path(relative_path):
    """ Get absolute path to resource, works for dev and for PyInstaller """
    base_path = getattr(sys, '_MEIPASS', os.path.dirname(os.path.abspath(__file__)))
    return os.path.join(base_path, relative_path)

<小时>

import sys
import resource_path # code taken from links above
from PyQt5 import QtGui
from PyQt5.QtWidgets import QApplication, QMainWindow

class Window(QMainWindow):
    def __init__(self):
        super().__init__()

        self.title = "MyProg"
        self.top = 400
        self.left = 400
        self.width = 680
        self.height = 540
        icon_path = resource_path("icon.png")
        self.setWindowIcon(QtGui.QIcon(icon_path))

        self.InitUI()

    def InitUI(self):
        self.setWindowTitle(self.title) 
        self.setGeometry(self.top, self.left, self.width, self.height) 
        self.show()

App = QApplication(sys.argv)
window = Window()
sys.exit(App.exec())

推荐答案

解决方案是将图片文件专门添加到.spec文件中，然后生成.exe使用

The solution was to specifically add the image files to the .spec file then generate the .exe file using

$> pyinstaller myGUI.spec

这是 .spec 文件的相关部分:

Here is the relevant part of the .spec file:

a = Analysis(['myGUI.py'],
     ...,
     datas = [('myIcon.png', '.')],
     ...)
