  pip is already installed if you are using Python 2 >=2.7.9 or Python 3 >=3.4 downloaded from python.org

  但 macox 上安装的py3.7 只有 pip3 命令,不管你本地有没有,先升级 pip。

  $ pip3 -V && pip3 install -U pip && pip -V

numpy:pip install numpy -i https://pypi.tuna.tsinghua.edu.cn/simple

    设置永久镜像源:mkdir ~/.pip && vi ~/.pip/pip.conf
