[开发工具]Mac 跑python程序安装numpy

在终端里，先查看一下python版本

% python -V

Python 2.7.16

% python3

Python 3.8.2 (default, Sep 24 2020, 19:37:08)

[Clang 12.0.0 (clang-1200.0.32.21)] on darwin

Type "help", "copyright", "credits" or "license" for more information.

运行一个python程序，报错ModuleNotFoundError: No module named 'numpy'

需要安装numpy，运行如下程序：% sudo pip3 install numpy

即可

再运行python程序就行啦

% python3 xxxx.py
