codespace： You don’t have permissions to push to “Name/Name of Project” on GitHub. Would you like to

问题描述：在github中使用codespaces编写代码，commit后执行Sync同步操作时报错：You don’t have permissions to push to “Name/Name of Project” on GitHub. Would you like to create a fork and push to it instead?

参考：Push to GitHub error

问题分析：受参考资料启发，主要原因没有设置SSH密钥，具体设置方法如下：

ssh-keygen -t rsa -C "your_email@example.com"

将~/.ssh/id_rsa.pub目录下的公钥放到github -> settings -> SSH and GPG keys下面，点击new SSH key，将id_rsa.pub内容粘贴进去即可。

再次提交的时候可能会出现的问题：

fatal: unable to access 'https://github.com/username/location.git/' The requested URL returned error: 403

将远程仓库的https变为ssh格式的即可

https://github.com/username/repo.git
变为：
git@github.com:[username]/[repositoryname].git
