Checking the the production error log I saw that the Javascript runtime was not found. That's confusing as it is obviously installed. So I went about forcing the Node

Calling Node.js script from Rails app using ExecJS

问题 I have a Rails application that needs to run a node script.

ExecJS::RuntimeError in rails 3.2.8 engine with javascript_include_tag

问题 In my rails application, I use highcharts to display some charts. And now, I need to generate a pdf with charts (I will use prawn). I want to know if I can use highcharts in my pdf. Maybe with ExecJS ? Or with an alternative to prawn ? Thanks! 回答1: You can use wkhtmltopdf (http://code.google.com/p/wkhtmltopdf/) to render the javascript charts as a PDF This blog post is helpful: http://www.claytonlz.com/index.php/2011/02/broken-highcharts-wkhtmltopdf/ 来源： https://stackoverflow.com/questions
