解决git@github.com: Permission denied (publickey). fatal: Could not read from remote repository.

ssh-keygen -t rsa -C "xxxxxxxx@qq.com"

xxxxxx@qq.com改为自己的邮箱即可，途中会让你输入密码啥的，不需要管，一路回车即可，会生成你的ssh key。（如果重新生成的话会覆盖之前的ssh key。）

1. 复制id_rsa.pub 的内容
2. github 找到设置
3. 然后找到 SSH and GPG Keys
4. 点击 New SSh key
5. 输入名称
6. 将复制的id_rsa.pub的内容粘贴到下面，保存
