如何正确要求 Composer 中的特定提交，以便它可用于依赖包?

How to correctly require a specific commit in Composer so that it would be available for dependent packages?(如何正确要求 Composer 中的特定提交，以便它可用于依赖包?)

问题描述

我有一个库 foo/foo-lib，它 需要 来自 GitHub 的特定提交:

I have a library foo/foo-lib which requires a specific commit from GitHub:

{
    "name": "foo/foo-lib",
    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/KnpLabs/Gaufrette.git"
        }
    ],
    "require": {
        "knplabs/gaufrette": "dev-master#2633721877cae79ad461f3ca06f3f77fb4fce02e"
    }
}

而且效果很好:

$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)                                 
  - Updating knplabs/gaufrette dev-master (2633721 => 2633721)
    Checking out 2633721877cae79ad461f3ca06f3f77fb4fce02e

Generating autoload files

但是当我在其他项目中需要该库时:

but when I require that library in other project:

{
    "name": "bar/bar-app",
    "repositories": [
        {
            "type": "vcs",
            "url": "ssh://git.example.com/foo-lib"
        }
    ],
    "require-dev": {
        "foo/foo-lib": "dev-master"
    }
}

它产生依赖错误:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for foo/foo-lib dev-master -> satisfiable by foo/foo-lib[dev-master].
    - foo/foo-lib dev-master requires knplabs/gaufrette dev-master#2633721877cae79ad461f3ca06f3f77fb4fce02e -> no matching package found.

所以我的问题是:如何正确 require 我的库中来自 GitHub 的特定提交，以便它可以在依赖包中使用?

So my question is: how to correctly require the specific commit from GitHub in my library, so that it would be available in dependent packages?

推荐答案

你必须在你的库和应用程序中显式地在该哈希处需要 Gaufrette 库，并带有 dev 标志.像这样的东西应该在应用程序 composer.json 中工作:

You'll have to explicitly require the Gaufrette library at that hash, with a dev flag, in both your library and your application. Something like this should work in the application composer.json:

{
    "name": "bar/bar-app",
    "repositories": [
        {
            "type": "vcs",
            "url": "ssh://git.example.com/foo-lib"
        }
    ],
    "require-dev": {
        "foo/foo-lib": "dev-master",
        "knplabs/gaufrette": "dev-master#2633721877cae79ad461f3ca06f3f77fb4fce02e"
    }
}

来自文档:

如果您的依赖项之一依赖于不稳定的包您还需要明确要求它，以及它足够的稳定标志.

If one of your dependencies has a dependency on an unstable package you need to explicitly require it as well, along with its sufficient stability flag.

文档还建议您需要在 bar/bar-app Composer 文件中包含 Gaufrette 的存储库，尽管在这种情况下这听起来没有必要.我不知道为什么.

The documentation also suggests that you'll need to include the repository for Gaufrette in your bar/bar-app Composer file, though it sounds like this wasn't necessary in this case. I'm not sure why.
