现象:提交git失败

ssh: Could not resolve hostname gitlab.abc.com: nodename nor servname provided, or not known
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

bug分析:

*问题1:可能是git没有配置ssh地址*
*问题2:配置了ssh,找不到地址*
*问题3:检查过remotes地址是否正确检查网路也是正常*

解决问题1方式: 添加ssh

	 cat ~/.ssh/id_rsa.pub    复制到git ssh设置里

解决问题2方式: hosts添加gitlab.abc.com

sudo vim  /private/etc/hosts
ping 获取ip,并添加 gitlab.abc.com路径 

解决问题3方式:

也是最常出问题的情况,多次尝试,刷新网络
