我正处于Thor任务中，我想在我的gem文件中为资产组添加gems（见下文）。
gem_group命令（从标准Rails应用程序模板中获知）在Thor任务中似乎不起作用（请参阅底部的错误）。
我怎样才能最好地在Thor任务中将gem添加到gem文件中的组？
欢迎任何想法 - 谢谢。
class ThorBuild < Thor
desc "add_gems", "Adds the gems I need"
def add_gems
puts "Running add_gems"
gem 'mongoid', '~> 3.0.15'
gem 'bson_ext'
gem 'less-rails'
gem 'devise'
gem_group :assets do
gem 'therubyracer', '= 0.10.0', :platforms => :ruby
gem 'twitter-bootstrap-rails'
end
end
end
输出看起来像这样......
