2、經過Homebrew安裝Python3

1.安裝Homebrew,能夠看我之前的博客,連接:HomeBrew的安裝blog

2.Homebrew安裝完成後,以後就是安裝Python3

先搜索:

$ brew search python

輸出:
app-engine-python          micropython                python3
boost-python               python                     wxpython
gst-python                 python-markdown            zpython
Caskroom/cask/awips-python               Caskroom/cask/mysql-connector-python
Caskroom/cask/kk7ds-python-runtime

 安裝Python3,等待......

$ brew install python3

安裝完成後,具體路徑是:/usr/local/Cellar/python3/3.6.0,能夠在finder中前往,

你能夠經過如下命令把軟件連接到LaunchPad中。以後就能夠在LaunchPad中啓動軟件了。

$ brew linkapps python3
