我正在Mac上开发一个Rails应用程序,我是新手测试,所以我只是将这些宝石添加到我的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:production,bundler(v1.0.21)仍然会尝试安装它们.......显然失败了!
extconf.rb:19:in '<main>': Only Darwin (Mac OS X) systems are supported (RuntimeError)

RAILS_ENV在运行之前设置为生产bundle install 不起作用.

它通过运行起作用bundle install --without development test,但是如何仅通过基于您的操作系统的捆绑器来考虑这些宝石？

编辑: bundler wiki提供有关如何使用platform作为参数的详细信息.
在捆绑问题#663中给出了相同的解决方案,所以我尝试了:

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

bundle install不起作用,但即使我们回到原点并做
bundle install --without darwin,结果是'darwin' is not a valid platform. …

我一直在努力让twitter-bootstrap-rails gem在我的windows机器上工作,并且在尝试安装'therubyracer'宝石时遇到了错误,这是一个较旧版本的较少宝石的依赖.

我认为升级到较低的2.2.1,这不依赖于therubyracer,但尽管它似乎认为我仍然需要安装therubyracer.这是我尝试启动rails服务器'rails s'时得到的错误输出.

$ rails s
[WARNING] Please install gem 'therubyracer' to use Less.
