Please install mysql adapter 'gem install activerecord-mysql-adapter'

Question

I\'m having trouble finding a solution to this problem. I\'m getting the error:

Please install the mysql adapter: \'gem install activerecord-mysql-adapter\'
         


        

Answer 1

It is possible that you have changed adapter to mysql2 for a certain environment only but are not passing the environment to the rake command.

E.g. I only changed mysql to mysql2 on the production environment but was running

rake generate_secret_token

when I changed it to the following it worked:

rake generate_secret_token RAILS_ENV=production
