使用Bundler时，为什么还要关心RVM的Gemset功能？ [英] Why should I care about RVM's Gemset feature when I use Bundler?

问题描述

我不明白。我以为 Bundler 是为了解决宝石之间的版本冲突而开发的。因此，我只需要要求捆绑软件/设置 ，一切都很好，知道 Bundler 将加载我所有宝石的正确版本，并且他们的依赖性。现在， RVM 非常适合管理多个红宝石，但是为什么我要关心Gemset功能？我在这里想念什么吗？它可以使我的发展更加轻松吗？也许，有些人可以给我一些有关开发和生产的完美 RVM + Bundler 工作流程的提示。

我也不知道 RVM 什么时候开始切换到另一个Ruby。我知道我的项目中可以有一个 .rvmrc 文件，但是我是否必须 cd 到此目录，所以

此外，由于 Passenger.prefpane <，我通常使用 Passenger 进行开发。 / code>，在 Mac OS 中的集成非常好。我是否仍可以使用RVM做到这一点，还是有更好的方法呢？ Passenger 是否识别 .rvmrc 文件并切换到正确的Gemset？

解决方案

为什么我在使用Bundler时应该关心RVM的Gemset功能？

不应该。

好吧，如果您想要，您可以关心，所以我最好说你不需要。

我只是听了对Bundler核心团队成员之一的播客采访，他们基本上说，自从他开始使用Bundler以来，他就停止使用Gemsets，因为它们是多余的。 / p>

这是一篇讨论相同问题的博客文章，并提供了一些示例。

I just don't get it. I thought, Bundler was developed to resolve version conflicts between gems. So that I just have to require "bundler/setup" and everything is fine, knowing that Bundler will load the correct versions of all my gems and their dependencies. Now, RVM is great for managing multiple Rubies, I know, but why should I care about the Gemset feature? Do I miss something here? Can it make my development even easier? Maybe, some of you can give me some hints on the perfect RVM + Bundler workflow for both, development and production.

I also don't know when RVM starts switching to another Ruby. I know that I can have an .rvmrc file in my project, but do I have to cd to this directory so that the switch happens?

Furthermore, I usually use Passenger for development since, thanks to the Passenger.prefpane, integration in Mac OS is great. Can I still do that with RVM or is there a better way to do it? Does Passenger recognize .rvmrc files and switch to the correct Gemset?

解决方案

Why should I care about RVM's Gemset feature when I use Bundler?

You shouldn't.

Well, if you want to, you can care about, of course, so I should better say "You don't need to."

I just listened to a podcast interview with one of the Bundler core team members who basically said that since he started using Bundler he stopped using Gemsets, because they are redundant.

Here's a blog post that discusses the same issue, with some examples.
