python - 尽管安装了模块，但导入错误 : No module named pynotify,

Question

>>> import pynotify
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named pynotify
>>> 

我已经安装了 py-notify 模块。这是我导入它时遇到的错误，我一想到它就失去了理智。

我只是想知道是不是路径的问题。当我打印出 sys.path 时，我得到了这个输出。有什么建议吗？

>>> import sys
>>> for x in sys.path:
...     print x

通过阅读tutorial在py-notify上，您将清楚地看到应该如何导入它。

你应该使用:

import notify

这是我在新的 python 2 virtualenv 中 pip 安装 py-notify 的完整示例，复制您的问题，然后按照教程所述正确导入:

▶ pip install py-notify
Collecting py-notify
  Using cached py-notify-0.3.1.tar.gz
