Execute tests in RubyMine causes "uninitialized constant Spring::Client::Run::UNIXSocket" on Windows 7

Question

In RubyMine, I try to run tests in debug (equivalent to rails test, but with debug mode in RubyMine). I get this log in RubyMine console:

Testing started at 08:44 ...
C:\Ruby23-x64\bin\ruby.exe C:/Ruby23-x64/lib/ruby/gems/2.3.0/gems/ruby-debug-ide-0.7.0.beta4/bin/rdebug-ide --disable-int-handler --evaluation-timeout 10 --evaluation-control --time-limit 100 --memory-limit 0 --rubymine-protocol-extensions --port 55232 --host 0.0.0.0 --dispatcher-port 55233 -- C:/Users/[ANONYMOUS]/bin/rails test

    C:/Users/[ANONYMOUS]/bin/rails:3:in `load'
    C:/Users/[ANONYMOUS]/bin/rails:3:in `<top (required)>'

Process finished with exit code 0

It seems like RubyMine tries to run against some UNIX configuration, but I couldn't find anything related to this in my files.

I run RubyMine with Ruby 2.3.3, on Windows 7, RubyMine 2018.1.4.

When I run tests without the debug mode, everything is fine.

How could I resolve this problem? Thanks.

You need to uninstall spring as it's not supported on Windows.

From thier README:

Spring makes extensive use of Process.fork, so won't be able to provide a speed up on platforms which don't support forking (Windows, JRuby).

To uninstall:

1. 'Unspring' your bin/ executables:

   spring binstub --remove --all
   

2. Remove spring from your Gemfile

3. Recreate your gemlock file by running:

   bundle install
