Fixed "There was a problem with the editor 'vi'"

在用git提交的时候 若是不当心打错了commit -m 'xxx' xxx里面的内容的话，能够修改，命令是git commit --amend

apple:yunlu_meeting apple$ git commit -m 'delete redu'
//这时候发现打字还没打完 电脑卡了手贱 多按了回车，郁闷，因而再一次修改提交信息
apple:yunlu_meeting apple$ git commit --amend
//WTF，`Vi`编辑器遇到问题,
error: There was a problem with the editor 'vi'.
Please supply the message using either -m or -F option.
复制代码

解决方法是

$ git config --global core.editor /usr/bin/vim -f
复制代码

完整的终端打印以下：

apple:yunlu_meeting apple$ git commit --amend
error: There was a problem with the editor 'vi'.
Please supply the message using either -m or -F option.
apple:yunlu_meeting apple$ git config --global core.editor  /usr/bin/vim -f
