rails console uses spring in deployment mode

[roscom]

Hi
I have rails 6 app deployed using:

bundle install --deployment --without=development test --quiet --path=... --gemfile=.../build/Gemfile

yet, running the rails console:

rails c
Running via Spring preloader in process 19088
WARNING: Spring is running in production. To fix this make sure the spring gem is only present in `development` and `test` groups in your Gemfile and make sure you always use `bundle install --without development test` in production
Loading production environment (Rails 6.0.1)
irb(main):001:0> 

uses spring, yet spring is defined in the development section of Gemfile, not production.

group :development do
  # Access an interactive console on exception pages or by calling 'console' anywhere in the code.
  gem 'web-console', '>= 3.3.0'
  gem 'listen', '>= 3.0.5', '< 3.2'
  gem 'spring'
  gem 'spring-watcher-listen', '~> 2.0.0'
  gem 'spring-commands-rspec'
  gem 'spring-commands-rubocop'

why is this so?

Can you verify if the srping gem is not being installed in production? If it is this seems like a bundler issue, not spring.

In rails 6.1.3.1 this is still a problem.

In my Gemfile, spring and spring-watcher-listen (and listen) are within group :development do block. And I guess since I had done a normal bundle install, the gems were indeed installed. However, they should only be used when Rails is running in development mode.

The first time I fired up RAILS_ENV=production rails console, I saw the warning about spring running. Then after exiting, I confirmed that the spring process was indeed running (for just a couple of minutes, starting exactly when I launched the console).

I gem uninstalled spring and spring-watcher-listen and attempted started the console in production. Rails console simply would not start because of the missing spring gems which it should not be attempting to load given the environment settings in the Gemfile and my command line launch.

$ RAILS_ENV=production rails c
Could not find spring-2.1.1 in any of the sources
Run `bundle install` to install missing gems.

Try updating your bin stubs. I think for me my binstub was old or stale. By updating it added a check to make sure that Spring only loaded in development or testing environments which resolved the issue for me.
