I am trying to learn rails by following the tutorial here. However when I got to the section on creating the model and ran this command:
bin/rails generate model Article title:string text:text
I got this error:
/usr/lib/ruby/vendor_ruby/spring/application.rb:152:in `serve': undefined method `cleanup!' for ActionDispatch::Reloader:Class (NoMethodError)
from /usr/lib/ruby/vendor_ruby/spring/application.rb:131:in `block in run'

This is my second go through so I know I have followed all the steps. Any idea where I might look for the solution or know what the solution is?
This really has me stuck.
Versions:
Ubuntu 16.04
ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]
gem 2.6.12
rails 5.1.0
Based on this issue, can you run spring stop and try to run your command again?
Restarting worked for me too, but I needed to do it every-time. Instead, I upgraded to to the latest version of spring (2.0.2) in my gemfile. This fixed it.

I have ruby on rails installed and something kinda went fubar on it. When I try to generate a controller, I get the following:

I've tried to uninstall/reinstall using gem and RVM but nothing seems to work.
Thanks.
The comments helped point in the right direction.
I did a gem upgrade (which I had to download because it kept telling me I had the latest). Then I did gem pristine --all, then spring stop. (Still wasn't working.) Then lastly, bundle install and voila! Such a hassle! Thanks!
I'm honestly so lost. Every time I try to run any rails commands ie, rails g controller home, the command line throws me this error and I have no idea what's going on. I've uninstalled and reinstalled spring and I've also googled.
Someone help please?

Thanks!
I think you have Spring gem installed and the name of controller is conflicting.
https://github.com/rails/spring
Try changing the name of controller. Hopefully it works. Cheers!
To the previous answer, you can have a controller named home (there's no naming issues with that). It does look like you have an issue with the version of the spring gem you are using. Have you tried running 'bundle install'? I checked the spring gem on Github and it does not look like there are any current issues with the gem. You could remove the spring gem and see if the issue persists, if so, then you know the issue lies deeper.
That is Exception backrace issue in spring gem.

warning: circular argument reference - xxxx was limited to Cucumber, which formerly was at 1.3.10. So I updated cucumber to 1.3.19. Now I am getting the error in active support. Has anyone else seen this.
I had a problem with Minitest preventing this project from advancing to RoR-4.1 back last spring. I do not know if this is pertinent or not but I include it for completeness.
In any case, who puts testing dependencies into distributed runtime code? Why is activesupport complaining about 'test/unit/assertions'?
Try upgrading from Rails 4.0.1 to 4.0.13
If that doesn't work, try using Ruby 2.1.5 to see if you get the same error message. I bet some gem you're using is running into this issue with Ruby 2.2. Example 1, Example 2. Example 3 from Rails.
The long term solution is to use Ruby 2.2 compatible gems, but by switching to 2.1.5 temporarily, you may be able to solve the problem in the short term and narrow down the specific gem versions that are causing the error.
i just add gem 'test-unit' in Gemfile and run 'bundle install' again. It is solved to me.
I wanted to generate a new migration for a site running Rails 2.3.14 and Ruby 1.8.7. I wrote the command
ruby script/generate migration AssetTable
Expecting the script to generate a file 20130522161112_asset_table.rb in the db/migrate directory. But I don't see this file. The output I get after running the above command is:

Depending on your rubygems versions, can you try to run:
$ gem install rubygems-update -v='1.4.2'
$ gem uninstall rubygems-update -v='1.5.0'
$ update_rubygems
Seen here: Gem dependency error in rails 2.3.4 :
This is happening because you installed RubyGems that is too new for
your version of Rails. Either downgrade (and re-run update_rubygems)
or upgrade Rails to 2.3.11.
I'm currently trying to get a Mongo database running alongside Devise. I'm using Rails 3.2.2 and Ruby 1.9.3, mongo_mapper 0.11.0, devise 1.1.9, and devise-mongo_mapper 0.0.2. I've referred to numerous sources online, but they seem to be invariably outdated.
A huge problem I'm facing right now involves devise-mongo_mapper. With mongod running on the terminal, trying to run the rails server gives me the following:

I checked online and found this could be because my devise isn't updated. Trying to update it gave me this:
Bundler could not find compatible versions for gem "devise":
In Gemfile:
devise-mongo_mapper (>= 0) ruby depends on
devise (~> 1.1.0) ruby
devise (2.0.4)
So basically, the older devise won't work, and the newest version isn't compatible with my current devise-mongo_mapper. Is there any way around this? Either a way to get all of these programs working together or a way to not need devise-mongo_mapper at all would be great.
Take a look at several of the forks.
They just bumped the version in the gemspec and the code probably works unchanged.
You can install whatever version of the gem you want using the -v argument.
sudo gem install whatever -v 1.0.1
Or you can look at the forks as Plastic Chicken suggested.
I was also facing the same error and running "bundle update" solved my problem.
