问题
打算从远程仓库克隆项目到本地时，报错：
$ git clone git@github.com:EverChan6/meetingDemo.gitCloning into ‘meetingDemo’…packet_write_wait: Connection to 52.74.223.119 port 22: Broken pipe // <== 就是它！！！fatal: Could not read from remote repository.Please make sure you have the correct access rightsand the repository exists.
解决
1. 从网上看了挺多解决办法，终于找到一个说辞是说
由于多日未 进行 ssh 登录操作，本地 publickey 失效造成的。
所以解决方法就是 Adding your SSH key to the ssh-agent
$ ssh-add ~/.ssh/id_rsaIdentity added: /c/Users/HP/.ssh/id_rsa (/c/Users/HP/.ssh/id_rsa)
2. 如果执行上面的命令出现如下错误
Could not open a connection to your authentication agent.
则先执行以下命令
$ ssh-agent bash
