无法在Ubuntu 16.04上安装pip

当我键入：

python get-pip.py
 Collecting pip

 Installing collected packages: pip, wheel
  Found existing installation: pip 18.0
    Uninstalling pip-18.0:

  Rolling back uninstall of pip

显示错误：

 Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/pip'
 Consider using the `--user` option or check the permissions.

我该怎么办？

Answer 1

这是一个权限错误。如果安装程序尝试访问的目录归root所有，则可能需要root用户才能安装pip。出于安全原因，如果您要尝试使用该路由，建议不要使用sudo安装/运行它。
