Question

PATH我說我的Python bin文件夾中的環境變量PATH，

export PATH=$PATH:/Library/Frameworks/Python.framework/Versions/2.7/bin 

但與下面的語句

set: Warning: path component /usr/local/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin may not be valid in PATH. 
set: No such file or directory 
set: Did you mean 'set PATH $PATH /Library/Frameworks/Python.framework/Versions/2.7/bin'? 
set: Warning: path component /usr/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin may not be valid in PATH. 
set: No such file or directory 
set: Did you mean 'set PATH $PATH /Library/Frameworks/Python.framework/Versions/2.7/bin'? 
set: Warning: path component /bin:/Library/Frameworks/Python.framework/Versions/2.7/bin may not be valid in PATH. 
set: No such file or directory 
set: Did you mean 'set PATH $PATH /Library/Frameworks/Python.framework/Versions/2.7/bin'? 
set: Warning: path component /usr/sbin:/Library/Frameworks/Python.framework/Versions/2.7/bin may not be valid in PATH. 
set: No such file or directory 
set: Did you mean 'set PATH $PATH /Library/Frameworks/Python.framework/Versions/2.7/bin'? 
set: Warning: path component /sbin:/Library/Frameworks/Python.framework/Versions/2.7/bin may not be valid in PATH. 
set: No such file or directory... 

發生了什麼故障？我只做其他許多事情（Google搜索）。使用的外殼是魚。

您正在使用在魚中不起作用的bash（或ksh）語法。

魚文檔涵蓋這裏設置PATH：http://fishshell.com/docs/current/tutorial.html#tut_path

你想要的語法是：

set PATH $PATH /Library/Frameworks/Python.framework/Versions/2.7/bin
