Rails (Puma server) Phantomjs don't run on production

Question

I want to run PhantomJs on Controller.

in my file test.js

use 'strict';
console.log('HELLO WORLD');

in my_controller.rb

def test
  rs = `phantomjs 'path/to/test.js' `
  puts rs
end

When i run project on local in mode development ,

• i go to action /test => it display 'HELLO WORLD' ( work )

But when i deploy, and run it on mode production It not display HELLO WORLD , seem like phantom js don't run.

I use Phantomjs 2.1.1, rails 5.1.5, ruby 2.3.5 and boot use Puma server. Anyone can show me a way can fix it.

Answer 1

try to make sure phantomjs is installed on your prod server, and the path setting is proper. run phantomjs from your shell to verify this
