使用RVM Gemsets&邦德勒红宝石矿 [英] Using RVM Gemsets & Bundler & RubyMine

问题描述

我使用RVM来管理Ruby版本.
在我的项目中，我使用Bundler管理该项目的gem.

I use RVM to manage Ruby versions.
In my project I use Bundler to manage gems for the project.

RVM也有宝石集.
宝石中的宝石与Bundler的宝石没有任何关系. ←这是正确的吗?
我得出这个结论是因为gem文件存储在不同的位置:
RVM宝石集:~/.rvm/gems/ruby-2.0.0-p247@myApp
捆绑软件:[my_app_dir]/vendor/bundle/gems
因此，应用使用的是Bundler宝石，而不是RVM宝石集宝石.

RVM also have gemsets.
Gem in gemset don't have a connection with Bundler's gem. ← Is this correct?
I came to this conclusion because gem files stored in different locations:
RVM gemset: ~/.rvm/gems/ruby-2.0.0-p247@myApp
Bundler: [my_app_dir]/vendor/bundle/gems
So app uses Bundler gems, not RVM gemset gems.

但是，当我将宝石添加到我的Gemfile中时，RubyMine IDE向我显示警告，该宝石不在RVM宝石集中.因此，我还将这个gem也添加到RVM gemset中(只是为了消除此警告).

But when I add gem to my Gemfile, RubyMine IDE shows me warning, that this gem is not in RVM gemset. So I add this gem to RVM gemset also (just to get rid of this warning).

所以问题是:

1. 是否有充分的理由在两个地方(RVM Gemset和Gemfile)添加gem?
2. 如果没有，那么RubyMine为什么要警告我呢?

推荐答案

1. 是否有充分的理由在两个地方(RVM Gemset和Gemfile)添加gem?

gemset是偶然的，Gemfile绝对是声明依赖项的地方.这些宝石的存放位置由您自己决定.

The gemset is incidental, the Gemfile is absolutely the place to declare your dependencies. Where you store those gems is up to you.

听起来好像Bundler已配置为将它们存储在项目本地路径中，但是您希望它们位于gemset中. Bundler通过在某个时候运行bundle install --path vendor/bundle/gems来获得该配置.它将配置存储在其项目配置文件中的project_dir/.bundle/config:

It sounds like Bundler is configured to store them in a project-local path, but you're expecting them to be in a gemset. Bundler got that configuration by running bundle install --path vendor/bundle/gems at some point. It stores that configuration in its project configuration file at project_dir/.bundle/config:

BUNDLE_PATH: vendor/bundle/gems

我不熟悉Rubymine，但是如果您使用Bundler(即bundle exec rails server)运行Rails服务器，则可以忽略该警告. Bundler将正确加载Gemfile中列出的宝石.

I'm unfamiliar with Rubymine, but if you run the Rails server using Bundler (i.e. bundle exec rails server) you can ignore that warning. Bundler will correctly load the gems listed in the Gemfile.

如果要使用Bundler缓存的宝石集 ，则只需从Bundler配置文件中删除该行，然后使用bundle install重新安装gem.

If you want to use a gemset instead of the Bundler cache, you can just remove that line from the Bundler configuration file and reinstall your gems with bundle install.

1. 如果没有，那么RubyMine为什么要警告我呢?

我的猜测是Rubymine不会读取Bundler项目配置(在project_path/.bundle/config中)，并且无法理解gem的安装位置.

My guess is that Rubymine is not reading the Bundler project configuration (in project_path/.bundle/config) and does not understand where the gems are installed.
