Homebrew 安装后 没法用brew命令。

Question

问题：运行brew时，终端提示”-bash:brew:command not found”，无法找到brew命令；

重新安装，终端显示：

It appears Homebrew is already installed. If your intent is to reinstall you

should do the following before running this installer again:

    ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

The current contents of /usr/local are bin Cellar etc Frameworks Homebrew include lib opt sbin share var

然后终端输入：ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

结果终端显示：Failed to locate Homebrew!
