Trouble installing Devise gem

I just attempted installing devise and had some trouble. From previous experience I know that when I install it I am required to do some manual steps. Well this time there where no manual steps but I still did them because I know they had to be done. So everything is working fine but then I run rails g devise: views this returns

/Users/henrywyatt/.rvm/gems/ruby-2.0.0-p353/gems/devise-3.2.2/lib/devise/rails/routes.rb:469:in `raise_no_secret_key': Devise.secret_key was not set. 
Please add the following to your Devise initializer: (RuntimeError)

config.secret_key = '1ef096dceb32ce5af3b11a7ef99c00ab59b7ad90ed5dbacabe5e8cb8613e437799333b96e2045997d701a1ed1b1fde537b98f6ef1c64d247516b85c9410ad147'

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

回答1:

You need to add

config.secret_key = '1ef096dceb32ce5af3b11a7ef99c00ab59b7ad90ed5dbacabe5e8cb8613e437799333b96e204599‌7d701a1ed1b1fde537b98f6ef1c64d247516b85c9410ad147'

to your devise file (config/initializers/devise_initializer.rb).

回答2:

if you are on production dont put this in any config file rather put it as environment variable rails 4 have one secret.yml file in which there is a line

secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>

you just need to set ENV["SECRET_KEY_BASE"]

I am not sure but secret key is any string

I too had the same problem but resolved it after restarting my rails server
