ubuntu不能安装pip unable to install pip in unbuntu

要用python中模拟用户信息，要装fake-factory. 

pip install fake-fatory

The program 'pip' is currently not installed. You can install it by typing:

sudo apt-get install python-pip

然后尝试 RUN sudo apt-get install python-pip

显示安装成功，但是一直报错

 

解决方案：重装。

 

sudo apt-get purge --auto-remove python-pip

sudo apt-get update

sudo apt-get -y install python-pip
