How to use mirror sources
1. Create a new pip folder in C:\Users\ma_pe\, and then create a new pip.ini file
2 Create a new pip.ini configuration file in the pip folder (create a new pip.txt and then change the suffix)
3 Open pip.ini and copy the following content into it
[global]
index-url=http://pypi.douban.com/simple/
[install]
trusted-host=pypi.douban.com
disable-pip-version-check = true
timeout = 6000
Then you can start using it, very fast.
