同步复刻

必须在 Git 中配置指向上游仓库的远程仓库，然后才能将您的复刻与上游仓库同步。

1. 打开 Terminal（终端）Terminal（终端）Git Bash。
2. 将当前工作目录更改为您的本地仓库。
3. 从上游仓库获取分支及其各自的提交。 Commits to BRANCHNAME will be stored in the local branch upstream/BRANCHNAME.

   $ 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://hostname/ORIGINAL_OWNER/ORIGINAL_REPOSITORY
   >  * [new branch]      main     -> upstream/main

4. Check out your fork's local default branch - in this case, we use main.

   $ git checkout main
   > Switched to branch 'main'

5. Merge the changes from the upstream default branch - in this case, upstream/main - into your local default branch. This brings your fork's default branch into sync with the upstream repository, without losing your local changes.

   $ git merge upstream/main
   > 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/main
   > Updating 34e91da..16c56ad
   > Fast-forward
   >  README.md                 |    5 +++--
   >  1 file changed, 3 insertions(+), 2 deletions(-)
