Error when running koudoku:install user

[ashkmehr1366]

I have gem 'koudoku' installed in my application. After running bundle install, I ran rails g koudoku:install user to install koudoku.

After running the command in my terminal, I get this error: Could not find generator 'koudoku:install'.

I have even re-installed the gem several times, but keep getting the same error.

PS: I use Rails 4.2 Any help is much appreciate.
