Python pip

I encountered a problem when installing pip and using:

pip
Traceback (most recent call last):
File "/usr/bin/pip", line 9, in <module>
 from pip import main
ImportError: cannot import name main

I found a post on the Internet, reinstalled to solve the problem, and reposted it

I encountered ImportError: cannot import name 'IncompleteRead' error while using pip on ubuntu,

Whether you enter pip, pip3 or pip3.4, it is the same. It is known on the Internet that this is a bug of python pip. I went to the Internet to find a lot of methods. Some people said to use sudo easy_install -U pip. Some domestic pypi mirror sources:
