在 ubuntu lucid 中，我默认有python 2.6.5。我编译python3.3.1并设置virtualenv，wrapper这样 workon envpy331 让我可以在 python3.3.1 上工作。然后我使用安装 yolkpip

现在，当我跑步时

>>yolk -l

它列出了即使在 python2.6.5 中安装的所有 python 库，如下所示，最后抛出一个 IOError

BeautifulSoup   - 3.0.7a       - active development (/usr/local/lib/python2.6/dist-packages)

    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'

知道为什么会这样吗？我需要再次编译python3并设置virtualenv吗？

在 github 上的 pull request 中找到了答案

这会让人们和工具（例如：https ://python3wos.appspot.com/ ）知道 yolk 与 Python 3 兼容。应该发布到 PyPI；似乎 GitHub 中的最新代码适用于 Python 3，但 PyPI 上最新发布的版本（0.4.3；发布于 2012-02-06）不适用于 Python 3。

所以请改用 github 版本
