解决python升级导致pip无法使用

raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'pip==7.1.0' distribution was not found and is required by the application

 

先查看以下目录/usr/local/python最新版本/lib/python最新版本/site-packages查看对应的pip版本，然后修改pip，代码如下：

vi /usr/local/bin/pip

将pip==7.1.0修改成pip==对应版本，就可以了
