RoR: Devise 500 error

I'm getting a 500 error when I go to /users/sign_in (or any other devise page).

This is all 开发者_运维百科the log says:

NameError (undefined local variable or method `root_path' for #<Devise::SessionsController:0x605f360>):

What is going wrong?

This looks suspicious:

ActiveRecord::StatementInvalid (Could not find table 'users'):

Have you run db:migrate since creating your User model?

Also,

NameError (undefined local variable or method `root_path' for #<Devise::SessionsController:0x605f360>)

suggests that you don't have a root path configured. This is something in routes.rb that matches requests to www.yourdomain.com/. You could use something like

root :to => "pages#home"

which would direct any request to www.yourdomain.com/ to the home action of the pages controller.
