It's Rails 3.1.0
What I did:
rails new site
cd site
rails s
The message I got:

Why did I get this error?
Can anyone give hint to fix it?
You may also need to install node.js (helped for me)
As the error mentions, you do not have a Javascript runtime installed. You should pick one yourself.
Add this to your Gemfile:
gem "therubyracer"
Then run bundle install and try again.
$sudo apt-get install nodejs
worked for me...
Just Open the file 'Gemfile' inside the root directory of your application folder, and then paste the below lines there.
gem 'execjs'
gem 'libv8'
gem 'therubyracer'
After pasting it, just save the file and execute 'bundle update' on the command prompt.
On finishing bundle update successfully, you try running 'rails s'. It works!!
Thank you.
By seeing your question, your system complains about the lack of JavaScript runtime.
you should visit https://github.com/sstephenson/execjs for a list of possibilities.
I would suggest you to download node.js from this http://nodejs.org/.
follow this way:
cd *your download dir*
tar xvf node-v0.4.11.tar.gz
cd node-v0.4.11
./configure
make
sudo make install
I am giving this answer because this works for me.
This answer will helpful to you.

This seems like a similar question to ExecJS and could not find a JavaScript runtime. The resolution here was to ensure NodeJS was installed on the machine:
sudo apt-get install nodejs
uncomment
gem 'therubyracer', platforms: :ruby
in your Gemfile.
Please do
bundle install
after adding 'therubyracer' gem

Just add a JavaScript runtime to your Gemfile (for example, execJS): gem 'execjs'
Then, just run bundle install and it should work.
Install node
sudo apt-get install nodejs
followed by
gem install execjs
or just put gem 'execjs' in your gemfile.

I went to the link that was provided: https://github.com/sstephenson/execjs
The Read Me under Install says:
gem install execjs
I do this and still get the same error. I am lost.
You have to first install a Javascript runtime, such as Node.js.
For Debian, there's installation instructions on Node.js Github
Edit: The ExecJS README lists the supported Javascript runtimes.
I did install therubyracer. I put the necessary gems insides the projects gem file. This seems to have solved this issue.
I am using Rails 3.2.9 with ruby 1.9.3 (made default using RVM). From the root directory of my test_app when I executed the command 'rails console' / 'rails c', the following error is showing.

Yes, I got the answer for my question.
Just Open the file 'Gemfile' inside the root directory of your application folder, and then paste the below lines there.
gem 'execjs'
gem 'libv8'
gem 'therubyracer'
After pasting it, just save the file and execute 'bundle update' on the command prompt.
On finishing bundle update successfully, you try running 'rails c' or 'rails console' for taking the rails console. It works!!
Thank you.
Install the folowing both:
gem 'execjs'
gem 'therubyracer'
Try installing
gem 'therubyracer'

I just started learning ruby on rails with "Lynda Ruby on Rails 3 Essential Training".
I finished the installation, and created rails application by writing- "rails new app".

Happy holidays,

Looks like you're missing some gems! try running bundle install... then all should work.
EDIT: make sure that your Gemfile contains the line
gem 'mysql'
before running bundle install. Bundler will get you set up for mysql, dependencies and all.
You have to go to this website and follow the directions ...
http://blog.mmediasys.com/2011/07/07/installing-mysql-on-windows-7-x64-and-using-ruby-with-it/
or in short download the connector mentioned in the article from mysql or a mirror site
Run this command:
gem install mysql --platform=ruby -- --with-mysql-dir=C:/mysql-connector-c-noinstall-6.0.2-win32
Make sure you have the correct path to the mysql connector folder that has no spaces!!
After that is complete make sure you copy the libmysql.dll file from the connector library you unzipped and downloaded and placed that in the Ruby\bin file.
After that delete the connector libary and start it up by typing 'rails server' making sure your gem file has the line gem 'mysql' or gem 'mysql2' I'm not sure which one so try both. It sucks and they really need to fix this for windows.
