如何在 git repo 中链接依赖项? [英] How can I have linked dependencies in a git repo?

问题描述

在我的脚本中，我经常使用拥有自己存储库的库(我的或其他人的).我不想在我的 repo 中复制那些，并在每次出现新版本时都坚持更新它们.但是，当有人克隆 repo 时，它应该仍然可以在本地工作并且没有断开的链接.

In my scripts, I often use libraries (mine or others') that have their own repos. I don't want to duplicate those in my repo and get stuck with updating them every time a new version comes out. However, when somebody clones the repo, it should still work locally and not have broken links.

对我能做什么有什么想法吗?

Any ideas about what I could do?

推荐答案

您可以使用 git 中的子模块执行此操作.在您的存储库中，执行以下操作:

You can do this with submodules in git. In your repository, do:

git submodule add path_to_repo path_where_you_want_it

因此，如果库的存储库具有 git://github.com/example/some_lib.git 的 URL，并且您希望它位于您的 lib/some_lib项目，你会输入:

So, if the library's repository had a URL of git://github.com/example/some_lib.git and you wanted it at lib/some_lib in your project, you'd enter:

git submodule add git://github.com/example/some_lib.git lib/some_lib

请注意，这需要从存储库的顶级目录中完成.所以不要cd进入你首先放置它的目录.

Note that this needs to be done from the top-level directory in your repository. So don't cd into the directory where you're putting it first.

在添加子模块后，或者每当有人对您的存储库进行全新检出时，您需要执行以下操作:

After you add a submodule, or whenever someone does a fresh checkout of your repository, you'll need to do:

git submodule init
git submodule update

然后您添加的所有子模块都将在您拥有的同一修订版中检出.

And then all submodules you've added will be checked out at the same revision you have.

当你想更新一个库的更新版本时，cd 进入子模块并拉取:

When you want to update to a newer version of one of the libraries, cd into the submodule and pull:

cd lib/some_lib
git pull

然后，当您执行 git status 时，您应该看到 lib/somelib 列在修改部分中.添加该文件，提交，然后您就是最新的.当协作者将该提交拉入其存储库时，他们会看到 lib/somelib 已修改，直到再次运行 git submodule update.

Then, when you do a git status you should see lib/somelib listed in the modified section. Add that file, commit, and you're up to date. When a collaborator pulls that commit into their repository, they'll see lib/somelib as modified until they run git submodule update again.
