无法在Mac上导出PATH

Question

我将python bin文件夹添加到环境变量中PATH，

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

但以下语句失败

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...

发生了什么？我和其他许多人一样（Google搜索）。所用的贝壳是鱼。

您正在使用bash（或ksh）语法，该语法在fish中不起作用。

fish文档涵盖了在此处设置PATH的方法：http：//fishshell.com/docs/current/tutorial.html#tut_path

您想要的语法是：

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