mac 使用brew 安装Python
- 安装brew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
- brew 下载python
brew install python3
- 因为mac 的Xcode 需要使用python2 所以不能将mac上的python2删除所以需要制作相关的alias（别名），打开terminal 然后
vim .bash_profile
输入 i 然后将下面的粘贴进去
alias python2='/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7'
alias python3='/usr/local/Cellar/python/3.7.3/bin/python3.7'
alias python=python3
source .bash_profile
键入python 显示的是python3
python
