" AttributeError:'NoneType'"每次我使用pip时都会显示 [英] "AttributeError: 'NoneType'" shows up everytime I use pip

问题描述

我可以安装轮子，但不能使用"pip install'module'"，就像我不能从Internet上安装那些模块一样.

I can install wheels but can't use "pip install 'module'", its like I just can't install those modules from the Internet.

错误

AttributeError:"NoneType"对象没有属性"startswith"

AttributeError: 'NoneType' object has no attribute 'startswith'

尽管有tensorflow，但pip仍无法安装"requests"或"numpy"之类的常用模块.

In spite of tensorflow, usual modules like "requests" or "numpy" can't be installed by pip.

C:\Users\Think>pip install tensorflow
Collecting tensorflow

似乎，您的python路径"D:\ Anaconda3"可能与使用pip install的错误有关.尝试在"C:\"上安装python.

It would seem, your python path "D:\Anaconda3" might have something to do with errors using pip install. Try to install python on "C:\".
