安装homebrew报错error: Not a valid ref: refs/remotes/origin/master 的解决方法

执行如下命令时：

　/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

报错：

==> Downloading and installing Homebrew...
HEAD is now at 8175e404e Merge pull request #7942 from sjackman/bottle_tag
error: Not a valid ref: refs/remotes/origin/master
fatal: ambiguous argument 'refs/remotes/origin/master': unknown revision or path not in the working tree.

 

这个错误是由于多次下载，导致一些冲突，最简单粗暴的解决就是卸载重装。因为我之前有几次安装中断了。

　　卸载homebrew

　　下载https://raw.githubusercontent.com/Homebrew/install/master/uninstall 并保存为 uninstall.rb，再执行 ruby uninstall.rb
