need help setting up ruby on rails javascript runtime environment

Question

I\'m having trouble setting up ruby on rails on my machine. I\'ve been following the book \"Agile Web Development with Rails\" and up until now everything has been going fine.<

Answer 1

I think you need a runtime like rubyracer. Try

sudo gem install therubyracer

Answer 2

If you will add therubyracer gem , may be your problem woould be solved

Code

gem 'therubyracer'
gem 'execjs'

then just do a bundle install

Answer 3

Your Gemfile should contain BOTH of the following lines:

gem 'execjs'
gem 'therubyracer'

Then run bundle install and try again.

Answer 4

Try this:

$ sudo apt-get install nodejs

Answer 5

I'd installed Node.js before Rails. Now its using Node.js as the javascript runtime by itself.

JavaScript Runtime  Node.js (V8)

Answer 6

If you're using Pacman packet manager you should use:

# pacman -S nodejs 

or

$ sudo pacman -S nodejs
