在Python 3.8中卸载numpy。我试着命令“pip 3 uninstall numpy”，但是没有用。我修改了~/.bashrc文件中的PYTHONPATH并导出了PYTHONPATH，但是当我再次安装nump时，“Requirement already satisfied：numpy in/usr/lib/python3/dist-packages（1.17.4）”的输出。

type here

~$ pip3 uninstall numpy
Found existing installation: numpy 1.24.1
Uninstalling numpy-1.24.1:
  Would remove:

设置PYTHONPATH不会影响软件包的安装，我真的建议不要在bashrc中使用PYTHONPATH hack，因为你不可避免地会忘记它们，并想知道以后到底发生了什么。
pip install numpy是说，因为你已经在/usr/lib/python3/dist-packages中安装了NumPy 1.17.4的系统级安装（可能是与apt一起安装的），而只是“我希望安装numpy”就满足了。
如果您尝试pip install -U numpy，它会尝试将Numpy升级到最新版本，并可能将其安装到您的.local目录，因为它无法写入您的dist-packages。但是也不要这样做-只要use a virtualenv and install the packages for your project there.
总之

$ python3.8 -m venv my-venv
$ source my-venv/bin/activate
$ pip install numpy
