Question

我有一个python脚本，我在升级到Lion之前已成功与py2app打包。

现在当我运行py2app时它完成没有错误，但是生成的.app只有216K，并且在执行时它抱怨缺少objc（这是脚本中的第一个导入）。

py2app输出：

运行应用程序：

$ ./dist/Hours-Worked.app/Contents/MacOS/Hours-Worked 
Traceback (most recent call last):

生成的应用程序如下所示：

$ du -hs dist/Hours-Worked.app/Contents/*

 76K    dist/Hours-Worked.app/Contents/MacOS
4.0K    dist/Hours-Worked.app/Contents/PkgInfo
132K    dist/Hours-Worked.app/Contents/Resources

过去看起来像：

$ du -hs Hours-Worked.app/Contents/*
4.0M    Hours-Worked.app/Contents/Frameworks
4.0K    Hours-Worked.app/Contents/Info.plist
188K    Hours-Worked.app/Contents/MacOS
4.0K    Hours-Worked.app/Contents/PkgInfo
 12M    Hours-Worked.app/Contents/Resources

如果没有看到setup.py文件，我最好的猜测是你没有明确地包含PyObjC库。例如

from setuptools import setup

OPTIONS = {'argv_emulation': False,
           'includes': ['objc'],
          }
setup(
    app='myapp.app',
    options={'py2app': OPTIONS},
    setup_requires=['py2app'],
)

将强制py2app包含objc库。如果你已经这样做了，那么看看你的setup.py脚本会很有帮助。

Lion上的py2app正在创建没有python框架或资源的空应用程序
