之前就安装过brew，然后家庭突然要用结果说
-bash: brew: command not found然后在桌面版的Cakebrew里面也显示brew未安装…那我就重新安一下吧
安装很顺利不过有个警告
Warning: /usr/local/bin is not in your PATH.
==> Installation successful!看了一下我的/usr/local/bin目录没问题啊…里面也有brew
然后用终端启动依然报错，才意识到有点问题。
-bash: brew: command not found解决办法：更改bash配置文件（主目录中的.bashrc或.profile），并添加以下行
export PATH=/usr/local/bin:$PATH感谢：http://*.com/questions/14288682/error-installing-homebrew-brew-command-not-found
