how can I do a get latest on a remote branch?
提问by Pindakaas
I am trying to catchup with the latest code from a remote github branch. Suppose this branch is called myDevBranch how can I get this locally? I tried:
我试图赶上来自远程 github 分支的最新代码。假设这个分支叫做 myDevBranch 我怎样才能在本地得到它？我试过：
git fetch myDevBranch
This returns :
这返回：
fatal: 'myDevBranch' 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.
Looks like a securuty issue or is there another way of getting the remote branch locally?
看起来像一个安全问题还是有另一种方法可以在本地获取远程分支？

You don't fetch a branch, you fetcha remote, so the correct line would be
你不获取分支，你fetch是一个遥控器，所以正确的行是
git fetch origin # or whatever your remote is called
Then the all tracking branches are updated, your updated code will be it a branch called origin/myDevBranch, again origin is replaced with your upstream name
然后更新所有跟踪分支，更新后的代码将是一个名为 的分支origin/myDevBranch， origin 再次替换为您的上游名称
To update your local branch you can merge the upstream git merge origin/myDevBranchbut you need to make sure that your HEADis pointing to your local branch of this remote (aka myDevBranch),
要更新您的本地分支，您可以合并上游，git merge origin/myDevBranch但您需要确保您HEAD指向此远程（又名 myDevBranch）的本地分支，
Or you can checkout to it git checkout origin/myDevBranchbut that would leave you in a detached head mode, you can create a new local branch from that remote using git checkout -b
或者您可以结帐到它，git checkout origin/myDevBranch但这会使您处于分离的头部模式，您可以使用该远程创建一个新的本地分支git checkout -b
If your HEADis pointing to your current branch, then you can do a git pull, keep in mind that pullwill do both fetchand merge, and if your branch has divergedfor any reason you would get a conflictthat you will need to resolve by your self.
如果您HEAD指向当前的分支，那么您可以执行 a git pull，请记住，这pull将同时执行fetch和merge，如果您的分支因任何原因发生分歧，您将得到 a conflict，您需要自己解决。
If you need to rebasethen you could either do a manual fetchand rebaseor you could do a git pull --rebase
如果你需要，rebase那么你可以做一个手册fetch，rebase或者你可以做一个git pull --rebase
