我在安装 Python 库（例如 Numpy、Sklearn 等）时遇到问题。我想将这些库与 Spyder 一起使用。我确实重置了我的 Windows，这是我重新安装我之前拥有的库的尝试。但我收到了这样的错误，我不知道这个错误的正确关键字。它在这里。

      Note: if you need reliable uninstall behavior, then install
      with pip instead of using `setup.py install`:

        - `pip install .`       (from a git repo or downloaded source
                                 release)
