我也有同样的问题。试试下面的方法: 1. 修改密钥链访问在Mac的git凭证解决了我的问题。 2. 重置原始url

git remote rm origin
git remote add origin git@github.com:account-name/repo-name.git

我的问题是我创建了一个没有权限的个人开发人员令牌

我在一台MAC上遇到了同样的问题，试图从我以前连接到的一个私人回购中提取。

我通过在回购url中包含我的用户名来解决这个问题:

git remote set-url origin https://<YOUR_USER_NAME_HERE>@github.com/<YOUR_USER_NAME_HERE>/<REPO>.git

然后我从回购中提取了数据。

对于一个你想克隆的新回购:

git clone https://<YOUR_USER_NAME_HERE>@github.com/<YOUR_USER_NAME_HERE>/<REPO>.git    

它会提示你输入那个账户的密码，然后你就可以去了。

这对我来说很管用:

1. 的遥控器

$ git remote rm origin
$ git remote add origin git@github.com:<USER>/<REPO>.git

如果您的SSH密钥已经在另一个github代表上使用，您可以生成一个新密钥。

2. 生成新的SSH密钥

$ ssh-keygen -t rsa -b 4096 -C "web@github.com"

3.在SSH代理级别添加密钥

$ eval "$(ssh-agent -s)"
$ ssh-add ~/.ssh/id_rsa_github

4. 将新密钥添加到Github回购。

我的解决办法是:

git remote rm origin
git remote add origin https://USERNAME@github.com/username/reponame.git

类似于Emi-C的答案，但没有密码。

Normally it happens because the project is private and you have not rights to write it. I had the same "problem" a few times, and it was for that reason. If the project it is yours, just create a private and a public key following this link: https://docs.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent and add them to the "SSH and Key" section on gitHub, then you will be able to push to the repo. In the other hand if the project it is not your, ask the owner to give you the rights for it.
