Setting up Rails Debugging in RubyMine

Question

I am really hoping someone can help with this as it is driving me mad.

I am trying to get Debugging up and running in RubyMine on Ubuntu and just having no luck at all. I have spent hours Googling and reading articles, trying different things with no joy.

All that happens when I run in debug mode is the following message comes up:

Fast Debugger (ruby-debug-ide 0.6.0, debase 0.2.1, file filtering is supported) listens on 127.0.0.1:56580

Then I get a loading bar that says waiting 10 seconds for Debugger. Then I get:

Process finished with exit code 143

I am at a loss of what to try, I have been struggling to even find a decent article about how to configure from scratch, i just get a lot of rather vague articles from RubyMine.

Is there any particular gems that are best to use (or even required) for debugging.

I am using Rails 4 and Ruby 2.2.1. I am pretty new to Ruby which is making the process much harder, but more important that I get it working!!

Many thanks David

EDIT

Here is my gemfile:

source 'https://rubygems.org'

gem 'rails', '4.2.4'
# Use postgresql as the database for Active Record

end

  gem 'spring'
end

group :test do
  gem 'faker'
  gem 'capybara'
  gem 'guard-rspec'
  gem 'launchy'
end

I have tried manually adding Debugger gem, rails-debugger-ui but with no joy so I took them out temporarily. I did have byebug in there which I have commented out because RubyMine complained the first time I tried to debug with it on and I am not really using it anyway, it is just something I added from a tutorial I started but haven't got round to finishing yet.

Many thanks for your help all.

Edit 2

I created a new project through RubyMine (before I did it through command line) and have done a simple test looping through an array for numbers in a controller and it has worked!! This time, the first time I ran the project it said it needed to install something which I said yes to, it didnt do this with my exising project before but the problem is I have no idea what it did. I have run a bundle show against both projects to see if it added any gems but I cannot see anything obvious. :

link to a diff, on the right is the test that does work, on the left is the one that doesnt

Any thoughts of what to try? Im reluctant to start a new project and move everything over into it if I can possibly help it.

Many thanks again

Edit 3

Many thanks for all the help.In the end I decided just to copy everything into a new project that I created through RubyMine itself rather than through terminal and that solved it.

Edit 4

I think I finally have everything working. After re-creating new projects over and over and copying my code back in line by line, the only difference I can find with what is working to the rest is that I am now running it from a folder that isn't being watched by Dropbox, I don't know how or why this would of affected it but it is the only explanation I can find.

Many thanks for all the help I have received

Answer 1

More often than now, RubyMine debugger will be able to configure itself on the first run.

It is however advisable to manually remove the console debuggers (pry, byebug, etc.) prior to running the RubyMine debugger.

Usually you do not have to add any extra configuration yourself. The special cases which actually require extra configuration can be found here.

If after cleaning your gemfile RubyMine still doesn't work, try removing the unused gems in the project by force.

`bundle clean --force`
`bundle install`

As a last resort scenario, create a new project and try the debugger in it to make sure that nothing funny is happening to your environment. If this works fine, try copy your gemfile contents over and later on code, step by step.

Answer 2

I had the same issue. Check your project's path for not-alphanumeric characters.

In my case the project was in the folder Me&Myself. After changing it to MeAndMyself it worked as expected.

I'm still trying to figure out the exact culprit to report the issue.
