I'm on a fresh Ubuntu 17.10 machine, Ruby 2.2.3 installed with RVM, and I'm trying to run a Rails 4.2 application.
After rails s command I get:

In rails console when I commit an error, the console displays tons of lines which I don't want to see. Can this be silenced?
I've found that you can add this line:
Rails.backtrace_cleaner.add_silencer { |line| line =~ /rvm/ }
in config/initializers/backtrace_silencers.rb but this doesn't resolve the problem.
