Ruby on Rails: LoadError: cannot load such file — paypal-express
Question
When I do
rake db:migrate
It simply fails. Here is log:
$ rake db:migrate

I tried suggestions given in this answer:
- I am already having gem 'paypal-express' in my Gemfile
I manually installed
paypal-expressgem:gem install paypal-express
Still no luck. Questioner of this question given clue that:
I needed to create the model from the terminal so I can run my migration
But I do not know how to do that (if I want to try it). Any help would be really appreciated. I am new to RoR.

I realized root cause of this problem was because I had forgotten to import DB (In other words, my DB was empty). I know it's silly mistake still I am posting it here in case it could help someone coming here in future. I imported DB by doing this:
sudo mysql -u root -p <db name> < /home/ubuntu/my_site_data.sql
