python - Py2app 模块图中出现错误

Question

几周前，我能够使用 py2app 构建应用程序。我刚刚再次尝试，在构建过程中，我被转储到 pdb session 中，堆栈跟踪如下。

它似乎存在 modulegraph.py 的导入问题，但我拥有迄今为止最新的版本。

即使只有一个最低限度的测试文件，除了 sys 之外没有任何导入，并且使用 py2applet 创建的设置，也会发生这种情况。

我还确保运行 py2app 的 python 是/Library 版本，而不是/System 版本。

有什么想法吗？

这似乎是一个已注意到的问题here并且应该在随后的 0.8 版本 modulegraph 中得到修复。确保您的 modulegraph 版本确实是最新的；该路径有点奇怪:build/bdist.macosx-10.6-universal/egg/modulegraph。看起来您使用的是私有(private)副本，而不是作为普通站点包安装的副本，例如 py2app (/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/站点包)。
