git commit--fatal: unable to auto-detect email address

git commit的时候报错

*** 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 'void@void-ThinkPad-E450.(none)')

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=your email
name=your name

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
[remote "origin"]
    url = https://github.com/VoidSem/user_rootfs_misc
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master
[user]
email=your@email
name=yourname　

然后再次提交就可以了
