active_support/secure_random LoadError - ruby-on-rails

I am migrating my rails app from Rails 2.3 to 3.2. I have ActiveSupport 3.2 dependency but at app startup I keep getting following error. I am not using active_support/secure_random anywhere in my code. Can someone please help me solve this problem?

ActiveSupport::SecureRandom was removed from rails 3.2 because rails 3.2 requires ruby 1.8.7 already has a builtin SecureRandom.
Replace any requires with
require 'securerandom'
And use SecureRandom instead.
If you're not using SecureRandom directly then you are probably using a gem that does, for example old versions of devise.

Ruby Upgrade Issues

I upgraded my ruby gem and rails to the latest version. Fixed all the dependencies but still, I am unable to start my rails application.
When I try rails s, I get the below error. I am not sure how to fix this. Any help would be appreciated.

Thanks

I think the problem is related to your ruby and rails version and I think you need to downgrade ruby version or upgrade the rails version
for more check here Ruby 2.4 and Rails 4 stack level too deep (SystemStackError)
To resolve this issue goto Gemfile use gem 'spring' don't add the version of the spring. Then do the bundle install. Still, you have an issue remove the Gemfile.lock then do the bundle install. I hope this will help you.

I note that the runtime.rb fails when trying to require 'zipruby' so I excluded that gem from being required by changing line 76 in require.rb to
pp required_file = file
Kernel.require(file) unless file == 'zipruby'
and that at least bypassed whatever the problem was.
Please let me know if you require further information to help in sorting out this problem.

I use postgres on my local also, and its working fine. This app was previously deployed on heroku. I have added ruby 2.0.0 in Gemfile and the logs indicate that they are using ruby 2.0.0. I am not sure how to debug this. Is there any other change required to migrate existing app on heroku to 4.0.
Any help would be appreciated.
Thanks in advance.
Your problem is during slug compilation the environment variables are not available to your app. Try installing the user-env-compile labs feature.

rails generate mailer psych.rb parse bug

I am new to ruby and rails and was working to setup my first mailer, and when I run the generate command my setup is blowing up. I am currently running ruby-1.9.3-p374 and have been searching for awhile now for a fix for this. My other generate commands work fine, just this one seems to be borked. Thoughts?

If you are using the figaro gem and your generators start blowing up, here is what killed me. In my application.yml file I had removed a space between the environment variable name and what it was set to. Instead of this =>> MY_VARIABLE:"VARIABLE" I needed to have this ==> MY_VARIABLE: "VARIABLE"
Hopefully this will save others TIME!

Am I missing some step , Do I have to re run the migration (I have the database ready with me with data in it)
any help?
Apparently the tmp directory Rails uses for session store is already present. Try deleting the /tmp folder in your release directory.
