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

概述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。

PIP版本virtualenv不匹配，不会升级

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。
