git中报unable to auto-detect email address 错误的解决拌办法

昨天刚配置好的git，今天刚要commit一些修改，就遇到了这个问题

** Please tell me who you are.Run
git config --global user.email "you@example.com"
git config --global user.name "Your Name"
to set your account's default identity.
Omit --global to set the identity only in this repository.
fatal: unable to auto-detect email address (got 'tim@newton.(none)')

后来找到了解决办法：
找到工程目录的.git文件夹，打开之后找到config文件，在最后边加上一句话

[user]
email = root@daimafengzi.com
name = daimafengzi
