"rails generate" not working

Question

When using ruby 2.1.0 (or 2.1.1) and I type rails g nothing happens. It simply hangs. But when I change to 1.9.3, using rvm use 1.9.3 it works as expected.

How can I debug this? What might be causing this command to hang, only on ruby > 2.0.0?

I have tried reinstalling both rails and ruby!

Are other ruby scripts impacted or only rails? Have you tried reinstalling ruby ? — Intrepidd, Apr 18 '14 at 15:46
Yes, I have tried reinstalling both rails and ruby! It seems like it only affects rails — subZero, Apr 18 '14 at 15:47
what about use 2.1 ruby again, "rvm use 1.9.3 && rvm use 2.1.0", rails gem exists? — Alexander Randa, Apr 18 '14 at 16:54
Yeah, they do. Thank you for the reply. Any other ideas on how I can debug? — subZero, Apr 19 '14 at 12:09
Same with me, I do not have ruby 1.9.3 installed, only 2.1.0. Do I have to install the lower version (again) and then "rvm use 1.9.3 && rvm use 2.1.0?btw I deleted 1.9.3 after installing 2.1.0 — Timo, Jul 01 '14 at 11:02

Have you tried to run:

spring stop

rails generate hangs may because spring is already running.

see https://github.com/rails/spring/issues/265

This was very hard to debug because no error was thrown. I had a different issue where it looked like the 'generator' worked in terminal, but no files were actually created. This worked like a charm – andrewcockerham Dec 10 '14 at 13:30
Thanks man! It's really hard to debug since there is no feedback... I think Zeus is a better alternative to Spring. https://rubygems.org/gems/zeus – rastko Mar 26 '15 at 07:42
Perfect Solution. Thanks a lot :) – A.M. Jun 13 '15 at 20:32
I was thinking the same thing @andrewcockerham ! – mrstebo Aug 01 '15 at 13:32

I tried all of this and it didn't work for me. Turns out that I had a bad rails file in my /bin folder.

This is what I had:

#!/usr/bin/env ruby
begin
  load File.expand_path("../spring", __FILE__)
rescue LoadError
end
require 'bundler/setup'
load Gem.bin_path('rails', 'rails')

And I just recreated a new rails app and copied the proper one:

#!/usr/bin/env ruby
begin
  load File.expand_path("../spring", __FILE__)
rescue LoadError
end
APP_PATH = File.expand_path('../../config/application', __FILE__)
require_relative '../config/boot'
require 'rails/commands'

This worked for me!
