what does this error on devise initialation means

Question

I'm trying to install the devise gem and when I do the

$ rails generate devise: install

I get the following error:

/usr/local/rvm/gems/ruby-2.0.0-p353/gems/devise-3.1.2/lib/devise/rails/routes.rb:440:in `raise_no_secret_key': Devise.secret_key was not set. Please add the following to your Devise initializer: (RuntimeError)

  config.secret_key = '964705f2d08f9196c511948baa14a1ef2ba7693b6eb326f9b177a1377d2c8487aab5736798e4bae6286eb0e36298eac3bceff31be5c357d356db8a22edd04a4d'

Please ensure you restarted your application after installing Devise or setting the key.

Any thoughts?

Why not read the error message? It is literally telling your what to do. Add `config.secret_key = '964705f2d08f9196c511948baa14a1ef2ba7693b6eb326f9b177a1377d2c8487aab5736798e4bae6286eb0e36298eac3bceff31be5c357d356db8a22edd04a4d'` to your devise.rb file. — Ashitaka, Jan 22 '14 at 00:45

This error is happens because of the new devise version, you probably are upgranding the gem version. Add this line into your config/initializers/devise.rb file

config.secret_key = '964705f2d08f9196c511948baa14a1ef2ba7693b6eb326f9b177a1377d2c8487aab5736798e4bae6286eb0e36298eac3bceff31be5c357d356db8a22edd04a4d'

Type: Generate another secrect_key insted of this old one

on your ruby console you can do this:

rake secret

Then copy the hash into your initializer

Kudos for @Ashitaka

The `rake secret` command is also convenient. – Ashitaka Jan 22 '14 at 00:50
