报错git@gitee.com: Permission denied (publickey).

前言:今天在windows下git push代码到gitee的时候，报错:

$ git push
git@gitee.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

原因:我电脑重装过了，可能ssh key变了

解决:

打开win10系统当前用户目录下的.ssh隐藏目录，把id_rsa.pub里面内容粘贴到gitee上面的公钥，然后提交代码就可以了
