  File "/usr/bin/pip3", line 9, in <module>
    from pip import main
  File "/usr/lib/python3/dist-packages/pip/__init__.py", line 14, in <module>
    from pip.utils import get_installed_distributions, get_prog

解决办法

换源

 //首先删掉之前下载的残次品

     apt-get remove python3-pip

 //有的换源教程给出只要四个地址就好，但是我用这样的源下载下来的pip3，使用时就会报错
 //也按照网上的错误改正教程操作过，但是没有卵用
 //换个源就好了
