I was trying to clone a repo and was facing this issue, I tried removing all git related credentials from windows credentials manager after that while trying to clone git was asking me for my credentials and failing with error invalid username or password. This was happening because the repo I was trying to clone was under an organization on github and that organization had two factor auth enabled and git bash probably do not know how to handle 2fa. So I generated a token from https://github.com/settings/tokens and used the github token instead of password while trying to clone the repo and that worked.

这里的问题是windows凭据管理器，请去控制面板，搜索凭据管理器，并删除它关于github的所有内容

因为您可能没有首先将远程git存储库标识到您的终端。

git remote set-url origin https://github.com/MyRepo/project.git

然后,

git add .
git commit -m "initial commit"
git push origin master

如果你在windows上得到控制面板-> windows凭据，然后从通用凭据选项删除github凭据。然后尝试克隆

这可能是身份验证的问题。SourceTree缓存你的github凭据(用于通过https访问存储库)，但从终端你必须使用凭据配置git (https://help.github.com/articles/creating-an-access-token-for-command-line-use/)或使用git+ssh和ssh密钥对(https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/)。

我有其他现有的github存储库，但我错误地认为我可以使用git命令创建存储库。我认为我的问题是没有个人访问令牌，但我仍然不能使用下面的命令来创建我的存储库。

git init
git add README.md
git commit -m "first commit"
git branch -M main
git remote add origin https://github.com/username/project.git
git push -u origin main

我不断地得到:

remote: Repository not found.
fatal: repository 'https://github.com/username/project.git/' not found

作为对

git push -u origin main

然而，我发现存储库需要创建使用github cli或在他们的github网站登录到我的帐户后。一旦我这样做了，一切都很顺利。

下面是我发现我不能用git命令创建github存储库的链接。
