I ran rake db:migrate, and the migration worked. However, it gives me this error when i try to use any rake command.
/Library/Ruby/Gems/2.0.0/gems/devise-3.5.6/lib/devise/models.rb:80:in `map': undefined method `to_sym' for nil:NilClass (NoMethodError)
I'm not sure how to fix this, as rake db:rollback also causes the error.
EDIT
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable,

and here is the whole error

Any clue?
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:
davide#davidell:~/app/app-backend$ rails s
Array values in the parameter to `Gem.paths=` are deprecated.
Please use a String or nil.
An Array ({"GEM_PATH"=>["/home/davide/.rvm/gems/ruby-2.2.3#app", "/home/davide/.rvm/gems/ruby-2.2.3#global"]}) was passed in from bin/rails:3:in `load'

I installed ActiveAdmin to manage the Admin end of my Rails app and everything was absolutely fine till I generated a model for ActiveAdmin. Now the rails server fails to start, even Rake Rollback or rails d active_admin:resource MyModel doesn't work. I am clueless now, might be a simple stupid error but still I can't figure it out, BTW here's the error dump.

I installed a WebRTC application developed in rails from this source: https://github.com/tokafish/pushertc and when I try to run it locally it shows me this error:
home/user/.rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/uri/rfc3986_parser.rb:17:in `rescue in split': bad URI(is not URI?): (URI::InvalidURIError)
Can somebody try this app and tell me what I am missing?
