git中报unable to auto-detect email address

git commit 时报错：

** 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)')

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（注意 = 左右的空格，还有符号的英文性）
［user］
 email = your email
 name = your name
