python - 无法在 MAC OS 中更新 pip

Question

我无法在 MAC OS 中更新 pip。

我猜可能是因为我安装了 PyCharm？!

但我不知道如何解决这个问题......

错误信息如下:

host-217:~ ChenGuanYing$ pip install -U pip

You should consider upgrading via the 'pip install --upgrade pip' command.

尝试使用

sudo pip install -U pip 

输入密码并运行。在此更新类型之后

pip --version

检查新的pip版本
