Error after removing # from routes.tb file

i am new to ROR. currently studying getting started with rails

i am getting "execjs: runtime error"after removing # from routes.tb
root line initially was like # root 'welcome#index’and it was working
as expected on localhost:3000 but after removing # it gave that error .i
searched a lot online and got some suggestions like
root “welcome#index”

root :to => “home#index”

i tried all the suggested but i am not able to remove that
error and couldn’t see my page .
what is the correct way to do it on ror 4.0.2

Hi Badal,

Have you tried installing the gem ‘therubyracer’?

Put the line:

gem ‘therubyracer’

in your Gemfile and execute bundle install on your console. Restart the
server and try again.
