本文是从 Github 同步你的fork 仓库的介绍。
Configuring a remote for a fork
You must configure a remote that points to the upstream repository in Git to sync changes you make in a fork with the original repository. This also allows you to sync changes made in the original repository with the fork.
List the current configured remote repository for your fork.
git remote -v origin https://github.com/YOUR_USERNAME/YOUR_FORK.git (fetch) origin https://github.com/YOUR_USERNAME/YOUR_FORK.git (push) Specify a new remote upstream repository that will be synced with the fork.
git remote add upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git Verify the new upstream repository you’ve specified for your fork.
git remote -v origin https://github.com/YOUR_USERNAME/YOUR_FORK.git (fetch) origin https://github.com/YOUR_USERNAME/YOUR_FORK.git (push) upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git (fetch) upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git (push)
Syncing a fork
Sync a fork of a repository to keep it up-to-date with the upstream repository.
Before you can sync your fork with an upstream repository, you must configure a remote that points to the upstream repository in Git.
- Open Terminal.
- Change the current working directory to your local project.
- Fetch the branches and their respective commits from the upstream repository. Commits to master will be stored in a local branch, upstream/master.
$git fetch upstream remote: Counting objects: 75, done. remote: Compressing objects: 100% (53/53), done. remote: Total 62 (delta 27), reused 44 (delta 9) Unpacking objects: 100% (62/62), done. From https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY * [new branch] master -> upstream/master
- Check out your fork’s local master branch.
git checkout master Switched to branch 'master'
- Merge the changes from upstream/master into your local master branch. This brings your fork’s master branch into sync with the upstream repository, without losing your local changes.
git merge upstream/master Updating a422352..5fdff0f Fast-forward README | 9 ------- README.md | 7 ++++++ 2 files changed, 7 insertions(+), 9 deletions(-) delete mode 100644 README create mode 100644 README.md
If your local branch didn’t have any unique commits, Git will instead perform a “fast-forward”:
git merge upstream/master Updating 34e91da..16c56ad Fast-forward README.md | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
Tip: Syncing your fork only updates your local copy of the repository. To update your fork on GitHub, you must push your changes.
