Python cx_freeze打包工具处理问题思路及解决办法

Jun 10, 2016 pm 03:06 PM

以下是在使用cx_freeze过程中遇到的问题及解决办法(Win7)

1.问题描述:运行exe,启动无数个主程序,导致系统无法使用

    原因:在程序中使用了multiprocessing的包

    解决办法:在主文件if __name__ == "__main__":后,添加multiprocessing.freeze_support(),一定要在添加在最开始处

2. 问题描述:运行后,提示在freeze_support中sys.stdout.flush处异常

   原因:使用的PyQT作为界面,没有控制台

   解决办法:在调用multiprocessing.freeze_support()前,重定向stdout和stderr,添加:sys.stdout = io.StringIO()和 sys.stderr = io.StringIO()

3.使用shelve模块,IDE下调试可以正常使用,打包后无法使用

    原因:shelve 的 open 函数在运行中还会装入其它的数据库管理模块,无从了解还需要哪些额外的包,故在打包时就漏掉了一些必要的模块

    解决办法:修改打包脚本,添加如下内容:

packages = []
for dbmodule in ['dbhash', 'gdbm', 'dbm', 'dumbdbm']:
try:
__import__(dbmodule)
except ImportError:
pass
else:
# If we found the module, ensure it's copied to the build directory.
packages.append(dbmodule)
options = {
'build_exe': {
'includes': 'atexit',
"packages": packages
}
}
Copy after login

4.使用inspect.getsourcelines异常OSError: could not get source code

  原因:打包后,都是pyc文件,没有源代码,导致动态获取代码失败

  解决办法:将包含所需源码的py文件打包到library.zip文件中,在‘build_exe'参数中,增加'zip_includes':['path\\source.py']

以上给大家分享了Python cx_freeze打包工具处理问题思路及解决办法,希望对大家有所帮助。
