下面是網友總結的:app
Mac系統自帶python路徑爲/System/Library/Frameworks/Python.framework/Version
python2.7
這裏可能會有多個python版本,裏面Current存放系統當前python版本,進入Current/bin
,工具
在終端輸入./python --version
便可查看系統當前python版本code
(注:若使用python --version
命令是查看用戶當前python版本而不是系統python版本)ip
HomeBrew安裝python路徑爲/usr/local/Cellar/python
裏面存放HomeBrew所安裝版本,it
進入2.7.13/bin
,在終端輸入./python --version
便可查看用戶當前使用的python版本。pip
若是使用brew工具正確安裝python的狀況下,用戶當前python版本會是新安裝的pythonio
系統命令默認路徑在/usr/bin
,用戶命令默認路徑在/usr/local/bin
(brew安裝的命令默認在這個路徑下)。class
若是存在相同的命令,則會依據/etc/paths
文件中的環境變量順序(前面優先於後面)依次查找,查看環境變量也能夠在終端輸入echo $PATH
查看,遵循左面路徑優先於右面路徑。
