'Could not find a version that satisfies the requirement matplotlib==3.4.3' Python 3.10 上的问题

Question

我需要Python 3.10上的pip install -r matplotlib==3.4.3的帮助。

下面是我的CMD输出:

Answer 1

根据setup.py:63: RuntimeWarning: NumPy 1.21.2 may not yet support Python 3.10.的提示，我决定卸载Python 3.10并替换为Python 3.9。我的问题解决了!
