You should consider upgrading via the 'pip install --upgrade pip' command.
也许我应该使用chown",但不知道如何使用它.请帮忙.
Maybe I should go with 'chown' but don't know how to use it. Please help.
推荐答案
由于您要升级系统范围的 Python,您需要以管理员权限运行此命令:
Since you want to upgrade your system-wide Python, you need to run this command with *****istrator privilege:
sudo pip install -U pip
但是,我建议您不要更改/污染您的系统范围的 Python.而是使用 virtualenv:
But, I recommend you not changing/polluting your system-wide Python. Instead use a virtualenv:
virtualenv myapp source myapp/bin/activate pip install -U pip # <- only if virtualenv is not up to date
