查看pip源和换源

查看当前pip源

(crawl) E:coding>pip config list
global.index-url='http://pypi.douban.com/simple'
global.timeout='6000'
global.trusted-host='pypi.douban.com'

更改pip源，在本次例子中更改成清华源

(crawl) E:coding>pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
Writing to C:UsersadminAppDataRoamingpippip.ini

再次查看当前pip源，发现已更换成功

(crawl) E:coding>pip config list
global.index-url='https://pypi.tuna.tsinghua.edu.cn/simple'
global.timeout='6000'
global.trusted-host='pypi.douban.com'

注：
有的需要先对pip进行升级才能更换源

python -m pip install --upgrade pip
