捆绑数据文件PyInstaller 2.1和MEIPASS错误--onefile [英] Bundling Data files with PyInstaller 2.1 and MEIPASS error --onefile

问题描述

这<一个href=\"http://stackoverflow.com/questions/7674790/bundling-data-files-with-pyinstaller-onefile/13790741#13790741\">question之前一直问，我似乎无法让我的PyInstaller正常工作。我在mainscript.py文件调用下面code：

This question has been asked before and I can't seem to get my PyInstaller to work correctly. I have invoked the following code in my mainscript.py file:

def resource_path(relative_path):
    """ Get absolute path to resource, works for dev and for PyInstaller """
    try:
        # PyInstaller creates a temp folder and stores path in _MEIPASS
        base_path = sys._MEIPASS
    except Exception:
        base_path = os.path.abspath(".")

    return os.path.join(base_path, relative_path)

当我运行PY文件（IDLE内），我的应用程序完美和负荷运行所有的数据文件。然而，当我与PyInstaller 2.1捆绑它（一个文件的方法）我得到的exe文件后出现以下错误生成：

When I run the py file (within IDLE), my app runs perfectly and loads all of the data files. However, when I bundle it with PyInstaller 2.1 (one file method) I get the following error after the exe builds:

Traceback (most recent call last):
File "<string>", line 37, in <module>
WindowsError: [Error 3] The system cannot find the path   
specified: 'C:\\Users\\Me\\AppData\\Local\\Temp\\_MEI188722\\eggs/*.*'

有没有人有我在哪里出了错什么想法？谢谢！

Does anyone have any idea where I went wrong? Thanks!

**编辑**

下面正是我想做的事情。

Here is exactly what I want to do.

我的主要脚本有一个设置（进口）看起来像下面。基本上我希望能够有Matplotlib，底图，并在所有IT资源路径：

My main script has a setup (imports) that look like below. Essentially I want to be able to have Matplotlib, Basemap, and resource path all in it:

import os,sys
import matplotlib
matplotlib.use('WX')
import wx
from matplotlib.backends.backend_wx import FigureCanvasWx as FigureCanvas
from matplotlib.backends.backend_wx import NavigationToolbar2Wx
from mpl_toolkits.basemap import Basemap
from matplotlib.figure import Figure
import matplotlib.pyplot as plt
import Calculate_Distance # A personal py file of mine

def resource_path(relative_path):
    """ Get absolute path to resource, works for dev and for PyInstaller """
    try:
        # PyInstaller creates a temp folder and stores path in _MEIPASS
        base_path = sys._MEIPASS
    except Exception:
        base_path = os.path.abspath(".")

    return os.path.join(base_path, relative_path)

bmap=wx.Bitmap(resource_path('test_image.png'))

print 'hello'

我使用PyInstaller 2.1。我也使用Python 2.7.5（32位）。我的操作系统是Windows 8（64位）。我Matplotlib是1.3.0和底图是1.0.6。 wxPython的是2.8.12.1（统一code）。

I am using PyInstaller 2.1. I am also using Python 2.7.5 (32 bit). My OS is Windows 8 (64bit). My Matplotlib is 1.3.0 and Basemap is 1.0.6. Wxpython is 2.8.12.1 (Unicode).

我去吩咐做：＆GT; pyinstaller myscript.py 。这会产生我的.spec文件，我微微编辑。下面是我的编辑规范文件：

I go to command and do: > pyinstaller myscript.py. This generates my .spec file which I slightly edit. Below is my edited spec file:

data_files = [('Calculate_Distance.py', 'C:\\Users\\Me\\Documents\\MyFolder\\Calculate_Distance.py',
              'DATA'), ('test_image.png', 'C:\\Users\\Me\\Documents\\MyFolder\\test_image.png',
              'DATA')]

includes = []
excludes = ['_gtkagg', '_tkagg', 'bsddb', 'curses', 'email', 'pywin.debugger',
            'pywin.debugger.dbgcon', 'pywin.dialogs', 'tcl',
            'Tkconstants', 'Tkinter']
packages = []
dll_excludes = []
dll_includes = []

a = Analysis(['myscript.py'],
             pathex=['C:\\Users\\Me\\Documents\\MyFolder','C:\\Python27\\Lib\\site-packages\\mpl_toolkits\\basemap\\*'],
             hiddenimports=[],
             hookspath=None,
             runtime_hooks=None)

pyz = PYZ(a.pure)
exe = EXE(pyz,
          a.scripts,
          a.binaries - dll_excludes + dll_includes + data_files,          
          name='MyApplication.exe',
          debug=False,
          strip=None,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=None,
               upx=True,
               name='MyApplication')  

我想这是一个文件的可执行所以数据文件应在可执行文件内包装。在其他pyinstallers我平时还没有与MEIPASS问题。但是，我需要使用2.1，因为Matplotlib和底图。如果有人能完美打造此exe - 可以请你告诉我，我需要调整？谢谢！

I want this to be a one-file executable so the data files should be packed within the executable. On other pyinstallers I usually haven't had issues with the MEIPASS. However, I need to use 2.1 because of Matplotlib and Basemap. If someone can build this exe perfectly -- can you please tell me what I need to adjust? Thanks!

* 修改的*

*EDIT*

如果任何人都可以找出如何用py2exe做到这一点 - 这将是巨大的。任何方式，我可以进入一个可执行文件，这将是值得的！

If anyone can figure out how to do this with py2exe -- that would be great too. Any way that I can get this into a single executable would be worth it!

推荐答案

我想我看到的问题。你不喂data_files到您的分析对象。
以下是我加入我的.spec文件我的数据文件：

I think I see the problem. You're not feeding data_files into your Analysis object. Here's how I add my data files in my .spec file:

a = Analysis(....)
a.datas += [('7z.dll', '7z.dll', 'DATA')]
a.datas += [('7z.exe', '7z.exe', 'DATA')]
a.datas += [('collection.xml', 'collection.xml', 'DATA')]
a.datas += [('License.html', 'License.html', 'DATA')]

pyz = PYZ(a.pure)

exe = EXE(pyz,
          a.scripts + [('O', '', 'OPTION')],
          a.binaries,
          a.zipfiles,
          a.datas,
          name=os.path.join('dist', 'blah.exe'),
          debug=False,
          strip=None,
          upx=False,
          console=True,
          icon=r'..\NCM.ico')

请注意我不使用COLLECT（）都没有。

Notice I'm not using COLLECT() at all.

如果您结账时的2.1文档： PyInstaller规格文件操作你会发现收集（）不用于--onefile模式

If you checkout the 2.1 documentation at: PyInstaller Spec File Operation you'll notice that COLLECT() isn't used for --onefile mode.

如果你看一下目录提取所指向sys._MEIPASS你可能会注意到，你的规范文件中数据文件根本不存在的。

If you look at the extracted directory pointed at by sys._MEIPASS you'll probably notice that with your spec file that the data file simply isn't there at all.

我希望这有助于。
