从Rails应用程序中查询依赖列表 [英] Query dependency list from within a rails app

问题描述

从运行rails应用程序有一种方法来枚举应用程序的依赖关系列表？假设我无法访问Gemfile或Gemfile.lock文件。

From a running rails app is there a way to enumerate the list of dependencies for the application? Assume I don't have access to the Gemfile or Gemfile.lock files.

我需要gem名称和版本号，例如：

I need the gem name and the version number so something like:

[["actionmailer" "3.1.3"]
 ["coffeescript" "2.0.2"]]

推荐答案

假设您应该使用bundler，您可以像这样访问它：

Assuming bundler, which you should use, you can access it like this:

Bundler.environment.current_dependencies
#=> [<Bundler::Dependency type=:development name="minitest" requirements=">= 2.11.0">,
    <Bundler::Dependency type=:development name="rspec-expectations" requirements=">= 2.7.0">,
    <Bundler::Dependency type=:development name="mocha" requirements=">= 0.10.0">,
    <Bundler::Dependency type=:development name="cucumber" requirements=">= 1.1.4">]
