Change local web server back to WEBrick in Rails from Puma

Question

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!

Answer 1

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
