Updating Oh My Zsh
fatal: remote error:

由提示文案可知，应该是说不再支持未授权的git协议了，

解决方案如下

1. 将你本地电脑上的ssh公钥保存到你的github下 (个人头像 -> 设置 -> SSH and GPG keys -> New SSH key)
   如果本地还没有ssh公钥的可参考本文章

2. 将协议git换成https也可
   查看配置文件 ~/.zshrc可知，其实oh-my-zsh 就安装在本地的 ~/.oh-my-zsh下面，下面有git clone之后的整套源码

   • 直接修改
     git remote set-url origin https://github.com/ohmyzsh/ohmyzsh.git
   • 先删后添
     git remote remove origin
git remote add origin https://github.com/ohmyzsh/ohmyzsh.git
   • 编辑配置文件
     进入.git目录，编辑config ,找到 url = 这一行, 将url的值修改为https的地址即可

[remote "origin"]
	url = https://github.com/ohmyzsh/ohmyzsh.git
	fetch = +refs/heads/*:refs/remotes/origin/*
