    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)
      - `pip install numpy`   (last NumPy release on PyPi)

推荐答案

您需要升级 setuptools 和 pip.你可以通过运行:

You need to upgrade setuptools and pip. You can do that by running:

pip install -U pip setuptools

然后你可以运行你的pip install numpy.
