PyInstaller：IOError：[Errno 2]没有这样的文件或目录：

Question

我想编译一个python脚本使用pyinstaller模块像科学，MMTK。 Pyinstaller无法包含一些.pyd模块，因此我将它们手动复制到dist文件夹中。当我执行编译的exe它给了我下面的错误： -

 
C:\Python27\hello\dist\hello>hello.exe

IOError: [Errno 2] No such file or directory: 'c:\\Python27\\hello\\build\\pyi.win32\\hello\\outPYZ1.pyz/turbulence3.tga' 

顺便说一句，我可以在那个位置看到outPYZ1.pyz文件。任何想法？

这不是关于pyd文件，而是关于找不到TGA文件。当应用程序由pyinstaller打包时，您需要调整软件以查看其他位置。据Accessing to data files：

In a --onedir distribution, this is easy: pass a list of your data files (in TOC format) to the COLLECT, and they will show up in the distribution directory tree. The name in the (name, path, 'DATA') tuple can be a relative path name. Then, at runtime, you can use code like this to find the file:

os.path.join(os.path.dirname(sys.executable), relativename)) 

In a --onefile distribution, data files are bundled within the executable and then extracted at runtime into the work directory by the C code (which is also able to reconstruct directory trees). The work directory is best found by os.environ['_MEIPASS2']. So, you can access those files through:

os.path.join(os.environ["_MEIPASS2"], relativename)) 

所以，如果你在你的程序中打开一个文件时，不要做：

fd = open('myfilename.tga', 'rb') 

此方法从当前目录打开该文件。所以它不能用于pyinstaller，因为当前目录将不同于数据放置的位置。

根据如果你正在使用--onefile，必须更改为：

import os 
filename = 'myfilename.tga' 
if '_MEIPASS2' in os.environ: 
    filename = os.path.join(os.environ['_MEIPASS2'], filenamen)) 
fd = open(filename, 'rb') 

或者，如果它是--onedir：

import os, sys 
filename = os.path.join(os.path.dirname(sys.executable), 'myfilename.tga')) 
fd = open(filename, 'rb')
