Mac 安装Python3
转载地址:https://cloud.tencent.com/developer/article/1383398
Mac默认是集成Python 环境的,一般是2版本。你可以在终端输入命令看一下:
zhangyudeiMac:~ zhangyu$ python
Python 2.7.10 (default, Jul 15 2017, 17:16:57)
[GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.31)] on darwin

我们想要安装下python3有两种方法安装:
一、第一种直接去官网下载安装: https://www.python.org/downloads/mac-osx/,有些人感觉这样装有点不能装逼。重点说下brew安装吧,
二、homebrew 安装,如果你是使用Mac的程序员,一定知道这个吧,本人很喜欢。如果不知道点这里傻瓜式教学安装。
Homebrew安装Python3详细步骤指令:
1、执行 brew search python
==> Searching local taps...
app-engine-python gst-python micropython python3
boost-python ipython python wxpython
boost-python@1.59 ipython@5 python-markdown zpython
==> Searching taps on GitHub...
caskroom/cask/awips-python caskroom/cask/mysql-connector-python
caskroom/cask/kk7ds-python-runtime
==> Searching blacklisted, migrated and deleted formulae..
2、这时候看到python3了,然后执行 brew install python3
如果成功你会看到最后几行:
They will install into the site-package directory
/usr/local/lib/python3.6/site-packages
See: https://docs.brew.sh/Homebrew-and-Python.html
==> Summary
�� /usr/local/Cellar/python3/3.6.4_2: 3,593 files, 56.2MB
/usr/local/Cellar/python3/3.6.4_2 这是路径,你可以打开看下:

3、这时候安装完成了,你可以在终端输入 python3和 python,然后你就会发现你同时拥有了2,3版本。
