py2app在Lion上生成没有python框架或资源的空应用程序

Question

我有一个Python脚本，之前在升级到Lion系统之前，我用py2app成功打包过这个脚本。

现在，当我运行py2app的时候，它完成得没有错误，但是生成的.app文件只有216K，而且运行的时候会提示缺少objc（这是脚本中第一个导入的模块）。

py2app的输出信息：

Answer 1

在没有看到你的 setup.py 文件的情况下，我猜测你可能没有明确地包含 PyObjC 这个库。比如说，

from setuptools import setup

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

这样做会强制 py2app 包含 objc 库。如果你已经这样做了，那我就需要看看你的 setup.py 脚本了。
