  问题记录：

  问题一： 重新add子module的时候提示： ‘repo’ already exists in the index

  解决办法：

  $ rm -Rf rack/
  
  $ git submodule add git@github.com:schacon/rack.git rack'rack' already exists in the index
  
  You have to unstage the rack directory first. Then you can add the submodule:
  
  $ git rm -r rack
  
  $ git submodule add git@github.com:schacon/rack.git rack

​ 在.gitmodules配置文件中删除子module的相关配置后要记得使用

git rm –cached path_to_submodule (no trailing slash).删除缓存否则别人删除的子module会一直报url找不到的错误
