linux - virtualenv yolk 调用中的 python3 导致 IOError

Question

在ubuntu lucid中，我默认使用python 2.6.5。我编译了python3.3.1并设置了virtualenv和wrapper，这样workon envpy331就可以让我在python3.3.1上工作。然后我使用pip安装了yolk

现在，当我运行时

>>yolk -l

它列出了即使在 python2.6.5 中也安装的所有 python 库，如下所示，最后抛出 IOError

  File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 1488, in get_metadata
    f = open(self.path,'rU')
IOError: [Errno 2] No such file or directory: '/usr/lib/python2.6/dist-packages/onboard-0.0.0.egg-info'

知道为什么会发生这种情况吗？我需要再次编译python3并设置virtualenv吗？

在 github 上的拉取请求中找到了答案

This will let people and tools (e.g.: https://python3wos.appspot.com/) know that yolk is compatible with Python 3. Should do a release to PyPI; it seems that the latest code in GitHub works with Python 3, but the last released version on PyPI (0.4.3; released 2012-02-06) doesn't work with Python 3.

所以请使用 github 版本
