Change local web server back to WEBrick in Rails from Puma


I was following the Heroku docs on getting Puma set up and entered this command:

bundle exec puma -t 5:5 -p ${PORT:-3000} -e ${RACK_ENV:-development}

Which made it so that now I run puma in my development environment whenever I run a rails s. But or whatever reason Puma is causing havok. How do I switch back to using WEBrick??

Tried

bundle exec webrick -p ${PORT:-3000} -e ${RACK_ENV:-development}

But of course, command is not found: webrick. Knew that' be too easy...

Thanks!


Solution

  • To run the local server in development with webrick you should only have to specify it when running rails server:

    rails server webrick
    

    You may get it to default back to webrick again if you move puma to the production group of your Gemfile:

    group :production do
      gem 'puma'
    end
    

    Then bundle without the production group:

    bundle install --without production
