pipexception:AttributeError:'NoneType'对象没有属性'startswith'

当我使用pip来安装一些软件包时,我总是得到相同的exception:

我发现类似的问题是python无法在win10中使用 , AttributeError:'NoneType'对象没有属性'startswith',并且无法在Python3.6中安装pip 。 但他们没有答案。


我在网上search了很长时间。 但没用。 我不知道。 请帮助或尝试提供一些想法如何实现这一点。

对于可能关注的人,有这个重复的帖子,在那里OP发现了解决这个问题的解决方案: 解决重复

看起来,您的Python路径“d:\”可能与使用pip install的错误有关。 尝试在“C:\”上安装python。
