Git Error

git error

• git clone错误
  原因是在github上已创建远程库，但是还没有init（创建后没有添加任何文件），这时候需要使用本地库init，添加远程库，然后push到远程（第一次必须加-u参数，否则无法pull，分支没有追踪的上游）

Cloning into 'master'...
ssh: Could not resolve hostname github: Name or service not known
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

• git push错误
  原因是没有设置远程仓库，git remote add origin git@github.com:user-name/repo-name.git，或git remote set-url origin git@github.com:user-name/repo-name.git

$ git push origin master
ERROR: Repository not found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

• git pull 错误
  原因是第一次push时没有加-u参数，push时同时设置分支追踪的上游，git branch --set-upstream-to=origin/master，设置上游

master has no tracked branch
