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

我安装了py-notify模块。这是我导入它时遇到的错误，我正在思考这个错误。

我只是想知道路径是否存在问题。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py-notify上的tutorial，您将清楚地看到假设如何导入它。

你应该使用：

import notify

以下是我在新的python 2 virtualenv中安装py-notify的一个完整示例，复制您的问题，然后根据教程所说的正确导入：

▶ pip install py-notify
Collecting py-notify
  Using cached py-notify-0.3.1.tar.gz
Building wheels for collected packages: py-notify
  Running setup.py bdist_wheel for py-notify ... done
  Stored in directory: /Users/####/Library/Caches/pip/wheels/50/af/6b/dd4386701fdb578f06c4c52e1dea195ae43b8bf9a7d0320e16

ImportError: No module named pynotify
>>> import notify
>>> dir(notify)

ImportError：尽管安装了模块，但没有名为pynotify的模块
