Rails, rake does not work

Add this to your Gemfile

gem 'therubyracer', require: "v8"

and run

bundle install

I have installed the gem therubyracer, execjs, mustang but nothing worked.

On my linux (ubuntu) the command

sudo apt-get install nodejs

did the job finally for me.

You need to install runtime for these.. some of the good options are

therubyracer - Google V8 embedded within Ruby

therubyrhino - Mozilla Rhino embedded within JRuby

Johnson - Mozilla SpiderMonkey embedded within Ruby

Mustang - Mustang V8 embedded within Ruby

Node.js

Apple JavaScriptCore - Included with Mac OS X

Mozilla SpiderMonkey

Microsoft Windows Script Host (JScript)
