解决python安装pip install mock报Could not fetch URL https://pypi.org/simple/mock/: There was a problem confirmin g the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443)的问题

问题：使用python2安装mock包，报

Could not fetch URL https://pypi.org/simple/mock/: There was a problem confirmin
g the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retri
es exceeded with url: /simple/mock/ (Caused by SSLError(SSLError(1, u'[SSL: CERT
IFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)'),)) - skipping
ERROR: Could not find a version that satisfies the requirement mock (from versio
ns: none)
ERROR: No matching distribution found for mock

 执行pip2 --trusted-host pypi.python.org install mock扔报同样的错误

在网上查阅，解决方法如下：

1、下载最新的pip工具包， pip工具下载的地址：  https://pypi.org/project/pip/9.0.1/#files

2、解压后，执行setup.py文件 前提是先去把python2的环境下面的python.exe改为python2.exe文件

 

然后再cmd下面输入：python2 setup.py isntall 

 

 出现下面的截图说明pip可以正常使用了！

3、这时候就可以使用pip2 这个命令安装任何包了。
