我不是git方面的Maven。
我编写了以下代码：

PS C:\Users\xxx\Desktop\Python Yamed> git branch
  explore
* master

我想从branchexplore中提取更新
我尝试了git pull，但这是我得到的消息：

There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.

    git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

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

我也试过

git pull origin explore

但我得到一个错误如下：

PS C:\Users\xxx\Desktop\Python Yamed> git pull origin explore
fatal: 'origin' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

一些可能有用的信息：
