Python Twisted twisted.internet

Question

我已经从 git 下载了 twisted

git clone -b 主干https://github.com/twisted/twisted.git

正如http://twistedmatrix.com/trac/wiki/Downloads 建议的那样。

然后我表演了

sudo python setup.py install

但是现在当我运行一些 python 文件时，我得到了

ImportError: 没有名为 twisted.internet 的模块。

我还注意到，在 git 的 README.rst 中，它没有提到模块 twisted.internet。

那么我应该去哪里买呢？

永远不要sudo pip install ... 任何东西。请改用virtualenv。
