php - Composer 在 Packagist 之前使用 Github

Question

我对FOSRestBundle做了一个 fork 这里RLovelett/FOSRestBundle it has a branch dev-411 .我想在 Symfony2 项目中使用我的 FOSRestBundle 分支。

为了尝试这个，我像这样修补了我的 symfony2 项目 composer.json(完整 composer.json):

 }

当我运行 composer update 时，我收到以下错误消息:

Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- The requested package friendsofsymfony/rest-bundle dev-411 could not be found.

Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting

我的配置有什么问题？

Answer 1

Composer 在分支名称前加上前缀 dev- 以清楚地识别它们，因此如果分支是 dev-411，那么它的 composer 版本就是 dev- dev-411.
