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.
Use '--' to separate paths from revisions, like this:
'git  [...] -- [...]'

原因

当安装多次失败时，会由于本地存在缓存，再次安装导致冲突。

解决

打开 链接，复制里面的内容，在终端使用如下命令创建一个uninstall.rb文件并将复制的内容粘贴到这个uninstall.rb文件里面，保存退出

链接里面的内容如下

#!/usr/bin/ruby

STDERR.print <

vi uninstall.rb

然后执行

ruby uninstall.rb

这样就解决了刚才的报错问题，然后再次尝试安装就好。
