Execjs and Could Not Find a JavaScript Runtime

ExecJS and could not find a JavaScript runtime

Ubuntu Users

I'm on Ubuntu 11.04 and had similar issues. Installing Node.js fixed it.

As of Ubuntu 13.04 x64 you only need to run:

sudo apt-get install nodejs

This will solve the problem.

sudo yum install nodejs

Could not find a JavaScript runtime. See https://github.com/rails/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable)

I force gem execjs to down to 2.7.0 since 2.8.1, it's works...

libv8 is an OS library; you'll need to install the correct Linux system library. If you're running Ubuntu, it's

sudo apt-get install libv8-dev

Alternatively, you can install node.js which is available as a Debian/Ubuntu package for various distros, e.g. http://ppa.launchpad.net/chris-lea/node.js/ubuntu

You may save yourself a lot of trouble by deploying on Heroku instead where you don't have to manage the OS or components for gems.
