Phusion Passenger and Rails app using NVM Could not find a JavaScript runtime

Question

I'm deploying a rails app using Apache and Phusion Passenger I already deployed apps using this stack but now i'm using NVM to install node but when I try to load the site shows an error, looking on logs shows this error:

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

On this server I didn't installed nodejs from OS repos, and looking on the passenger documentation shows something about passenger_nodejs but this is from nginx.

This is my conf from apache:

ServerName yourserver.com

# Tell Apache and Passenger where your app's 'public' directory is
DocumentRoot /var/www/myproj/public

PassengerRuby /home/appuser/.rvm/gems/ruby-2.3.0/wrappers/ruby
PassengerNodejs /home/appuser/.nvm/versions/node/v6.9.2/bin/node


# Relax Apache security settings
<Directory /var/www/myproj/public>
  Allow from all
  Options -MultiViews
  # Uncomment this if you're on Apache >= 2.4:
  Require all granted
</Directory>

and keep showing that error

Installing nodejs from OS repos fix the message and the app works but is because it's using the node version from OS but I want to use the NVM version.

Answer 1

I have the same problem and don't have a good solution but I did find I was able to get around my problem by creating a symbolic link like:

ln -sf /home/deploy/.nvm/versions/node/v6.10.1/bin/node /usr/local/bin/node

Doesn't work very well if there are multiple deployments on the same server but I also couldn't find a way to "properly" use NVM with Passenger / Rails.
