如何添加Mac特定的宝石捆绑在Mac上，但不是在Linux上？ [英] How to add Mac-specific gems to bundle on Mac but not on Linux?

问题描述

我在Mac上开发Rails应用程序，而我是新手，因此我只是将这些宝石添加到 Gemfile 中：

  group：test：：development do 
 gem'rspec-rails'
 gem'rb-fsevent'
 gem'growl'
 end 
  

但是我的生产服务器运行Linux，所以即使它们没有分组在：production ，bundler（ v1.0.21 ）仍会尝试安装它们。 ...并且很明显失败！

extconf.rb：19：'< main>'：只支持Darwin（Mac OS X）系统（RuntimeError） code $ <



在运行 bundle install RAILS_ENV 设置为生产c $ c> 不起作用。

它通过运行 bundle install --without development test code>，但这些宝石如何才能被bundler仅考虑到您的操作系统？

编辑： bundler wiki提供了有关如何将平台作为参数。

相同的解决方案在捆绑商问题＃663 中给出，所以我尝试：

  group：test，：development do 
 gem'rspec-rails'
 platforms：达尔文do 
 gem'rb-fsevent'
 gem'growl'
 end 
 end 
  

bundle install 不起作用，但即使我们回到原点并执行

bundle install --without darwin ，结果是'darwin'不是有效的平台。

可用选项为：[：ruby，：ruby_18，：ruby_19，：mri，：mri_18，：mri_19，：rbx，：jruby，：mswin，：mingw，：mingw_18，：：mingw_19]

其他任何（优雅）方法？

解决方案Gemfile实际上是一个常规的ruby文件，所以你可以使用类似于

pre $ case $ RUBY_PLATFORM
当/ darwin /
gem'foo'
当/ win32 /
gem'bar'
结束


I'm developing a Rails app on a Mac, and I'm new to testing, so I just added these gems to my Gemfile:

group :test, :development do
  gem 'rspec-rails'     
  gem 'rb-fsevent'
  gem 'growl'
end

But my production server runs Linux, so even if they aren't grouped in :production, bundler (v1.0.21) still attempts to install them. ...and fails, obviously!
extconf.rb:19:in '<main>': Only Darwin (Mac OS X) systems are supported (RuntimeError)

Setting RAILS_ENV to production before running bundle install doesn't work.

It worked by running bundle install --without development test, but how can these gems be taken into consideration by bundler only based on your OS?

Edit: The bundler wiki provides details on how to use platform as a parameter.
The same solution is given in bundler issue #663, so I tried:

group :test, :development do
  gem 'rspec-rails'     
  platforms :darwin do
    gem 'rb-fsevent'
    gem 'growl'
  end 
end

bundle install does not work, but even if we go back to square one and do
bundle install --without darwin, the result is 'darwin' is not a valid platform.
The available options are: [:ruby, :ruby_18, :ruby_19, :mri, :mri_18, :mri_19, :rbx, :jruby, :mswin, :mingw, :mingw_18, :mingw_19]

Any other (elegant) approaches?

解决方案

Gemfile actually is a regular ruby file, so you can use something like

case RUBY_PLATFORM
when /darwin/
  gem 'foo'
when /win32/
  gem 'bar'
end
