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
ubuntu不能安装pip unable to install pip in unbuntu
