无法从GitHub分叉存储库签出分支

Question

我正在尝试从分叉存储库中签出一个分支，但是它给出了一个错误：

存储库：https://github.com/tmsblgh/codechecker/tree/issue799

MacBook-Pro:codechecker tmsblgh$ git branch -vv
* master acdc482 [origin/master] Merge pull request #1636 from gyorb/version68
MacBook-Pro:codechecker tmsblgh$ git --version
git version 2.17.1
MacBook-Pro:codechecker tmsblgh$ git fetch
MacBook-Pro:codechecker tmsblgh$ git checkout issue799
error: pathspec 'issue799' did not match any file(s) known to git.
Baloghs-MacBook-Pro:codechecker tmsblgh$ git remote -v
origin  https://github.com/tmsblgh/codechecker.git (fetch)
origin  https://github.com/tmsblgh/codechecker.git (push)
MacBook-Pro:codechecker tmsblgh$ git checkout issue799
error: pathspec 'issue799' did not match any file(s) known to git.

Answer 1

当地的回购公司似乎没有origin/issue799。

#fetch the branch
git fetch origin issue799

#see if origin/issue799 exists
git branch -a

#if yes
git checkout issue799

#if not, create the local branch from FETCH_HEAD
git checkout -b issue799 FETCH_HEAD

#the next push after you make some new commits
git push -u origin issue799

Answer 2

此分支可能不在本地git设置中。试试git checkout origin/issue799

来源是你所指的遥控器。

Answer 3

您可以设置一个本地分支来跟踪远程：

git checkout -b issue799 origin/issue799

我不知道你为什么会出错，但下面是我从零开始做的事情，它似乎对我有用：
