You are using pip version 9.0.3, however version 21.2.4 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.*

我尝试了它提供的命令： python -m pip install --upgrade pip

它什么也没显示。之后，我再次尝试“pip install ipython”，同样的错误弹出。

解决方案

我就是这种情况。通过键入此命令easy_install -U pip，它对我有用。
