GitHub推送本地库到远程库报错Please make sure you have the correct access rights and the repository exists.

一、问题原因及报错展示

1.原因

• 没有权限

Permission denied (publickey)：权限被拒绝(公钥)

• 出现这错误一般是以下两种原因：
  • 1.客户端与服务端未生成 ssh key
  • 2.客户端与服务端的ssh key不匹配

2.报错展示

2.1.第一次执行推送本地库到远程库命令报错（报错如下图所示）

The authenticity of host 'github.com (20.205.243.166)' can't be established.
ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])? 
Warning: Permanently added 'github.com' (ED25519) to the list of known hosts.
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

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

2.2报错后再次执行推送本地库到远程库命令还是报错（报错如下图所示）

[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

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

二、解决方法

1.查看是否生成密钥（打开Git Bash执行下面命令）

ls -al ~/.ssh

此处可以看到一对文件，其中以.pub结尾的是公钥文件，另一个没有后缀的是私钥文件。

2.生成SSH密钥（打开Git Bash执行下面命令）

• github官方文档：https://docs.github.com/zh/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent?platform=windows

ssh-keygen -t rsa -b 4096 -C "邮箱号"

此处邮箱号为创建GitHub账号的电子邮件地址，途中会让你输入密码啥的，不用管，一路回车即可，则会生成SSH密钥（如果重新生成的话会覆盖之前的SSH密钥）。

3.查看公钥文件（根据生成SSH密钥提示查看公钥文件所在目录位置）

4.将SSH公钥添加到GitHub

1. 登录GitHub，点击头像

   

2. Settings

   

3. SSH and GPG keys→New SSH key

   

4. 复制公钥

   

5. 填写标题→粘贴公钥→Add SSH key

   

6. 添加成功

   

7. 推送本地库到远程

   

8. GitHub查看推送内容
