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.

我也遇到过类似的问题。错误的凭据缓存在OS X的密钥链中。

查看:https://help.github.com/articles/updating-credentials-from-the-osx-keychain

都经历过同样的问题。几年来一切都很正常，然后突然出现了这个错误。

问题是，我在用户的github SSH密钥(我总是用来访问有问题的回购)之前向我的SSH代理添加了另一个回购的部署密钥。SSH代理首先尝试了另一个回购的部署键，而GitHub出于一些完全无法解释的原因说

ERROR: Repository not found.

一旦我从SSH代理中删除了部署键，一切就恢复正常了。

首先在命令行上创建一个新的存储库，命名为adim .git

在命令行上创建一个新的存储库

触摸README.md git init git添加README.md Git commit -m "第一次提交" git远程添加origin https://github.com/your_name/Ademo.git Git push -u origin master

从命令行推送现有存储库

git远程添加origin https://github.com/your_name/Ademo.git Git push -u origin master

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

有类似的问题。问题的根源是我遵循了一些关于向Github添加新存储库的在线教程。

只要去Github，创建一个新的repo，它会要求你添加一个README，不要添加它。创建它，你会得到如何推送的指导。

它类似于接下来的两行:

git remote add origin https://github.com/YOUR_USER/your-repo.git
git push -u origin master
