How to execute Ruby program with locally installed gems?

问题

I have installed my dependencies using

bundle package

Then transferred them to the offline server and running:

> bundle install --local
Using mime-types (1.19)
Using rest-client (1.6.7)
Using trollop (1.16.2)
Using bundler (1.1.4)
Your bundle is complete! It was installed into ./vendor/bundle

However, it is not possible to run the application:

ruby someprogram.rb
/usr/local/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- trollop (LoadError)
        from /usr/local/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
        from someprogram.rb:2:in `<main>'

What do I need to specify to Ruby to be able to run locally installed gems?

回答1:

You're missing bundle exec in front of your ruby someprogram.rb command.
