1.原因：

公钥出现问题

2.解决办法：

(1)在需要提交文件的目录内，重新设置git用户名字和邮箱

git config --global user.name "yourname" #yourname你设置的名字
git config --global user.email "your@email.com" #你的邮箱

(2)生成密钥

ssh-keygen -t rsa -C "your@email.com" #填写设置的邮箱
#回车出现：
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/yz/.ssh/id_rsa):  #请按下回车

Enter passphrase (empty for no passphrase): #回车
Enter same passphrase again: #回车

#出现Your public key has been saved in /c/Users/yz/.ssh/id_rsa.pub 表示成功，公钥保存在/c/Users/yz/.ssh/id_rsa.pub
#复制id_rsa.pub内的公钥

(3)打开github，进入设置

点击左侧的 SSH and GPG keys，新建ssh key，将刚才复制公钥粘贴，然后点击添加即可。
