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 <command> [<revision>...] -- [<file>...]'
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 <<EOS
Warning: The Ruby Homebrew uninstaller is now deprecated and has been rewritten in
Bash. Please migrate to the following command:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"
EOS
Kernel.exec "/bin/bash", "-c", '/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"' + ' uninstall ' + ARGV.join(" ")
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。
