fatal: You are on a branch yet to be born

这个错误通常是因为你在一个尚未存在的分支上进行了操作。你需要先创建一个新的分支，然后才能在该分支上进行操作。你可以使用以下命令创建一个新分支并切换到该分支：

git checkout -b <branch-name>

其中，`<branch-name>`是你想要创建的新分支的名称。创建并切换到新分支后，你就可以在该分支上进行操作了。

fatal: The current branch dev has no upstream branch.

This error message indicates that the branch you are currently on, "dev," does not have an upstream branch set. An upstream branch is a branch on a remote repository that your local branch is tracking.

To set an upstream branch for your local branch "dev," you can use the following command:

git branch --set-upstream-to=origin/dev dev

This assumes that the remote repository is named "origin" and that there is a branch named "dev" on the remote repository. Adjust the command accordingly if your remote repository or branch names differ.

Once you set the upstream branch, you should be able to push and pull changes to and from the remote repository using the branch name alone.
