如何解决 fatal: The current branch beta has no upstream branch.

这个问题可以通过设置 upstream 分支来解决。您可以使用以下命令将 upstream 分支设置为 beta：

git branch -u <upstream> beta

其中，<upstream> 是您要将 beta 分支关联到的上游分支的名称或远程引用。如果您想将 beta 分支关联到远程分支，可以使用以下命令：

git branch --set-upstream-to=<remote>/<upstream> beta

其中，<remote> 是远程仓库的名称，<upstream> 是上游分支的名称。

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.

fatal: The current branch master has no upstream branch.

这个错误通常表示当前分支（master）没有与之关联的上游分支。上游分支是指远程仓库中与本地分支对应的分支。在执行与远程仓库相关的操作时，如推送或拉取代码，Git需要知道当前分支的上游分支以确定操作的目标。

解决该问题的方法之一是手动设置当前分支的上游分支。你可以使用以下命令将远程仓库中的某个分支设置为当前分支的上游分支：

git branch --set-upstream-to=<remote>/<branch>

其中，`<remote>`是远程仓库的名称，`<branch>`是远程分支的名称。例如，如果你想将远程仓库`origin`的`master`分支设置为当前分支的上游分支，可以执行以下命令：

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

执行完上述命令后，再次执行相关的远程操作应该就不会出现该错误了。
