Rails 5.2.1 triggers `ActionView::Template::Error (undefined not callable)`

[Al-un]

Problem

Having Rails 5.2.1, server successfully starts up but on the first page load, an error appears from my application.html.erb:

ActionView::Template::Error (undefined not callable):
     5:     <%= csrf_meta_tags %>
     6:     <%= csp_meta_tag %>
     7:
     8:     <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track': 'reload' %>
     9:     <%= javascipt_include_tag 'application', 'data-turbolinks-track': 'reload' %>
    10:

(execjs):1
app/views/layouts/application.html.erb:8:in `_app_views_layouts_application_html_erb__765064803_56530640'

Configuration

From bundle list:

• Rails 5.2.1
• autoprefixer-rails 9.3.1
• bootstrap 4.1.3
• jquery-rails 4.3.3
• sprockets 3.7.2
• sprockets-rails 3.2.1

My application.scss has @import "bootstrap":

@import 'my-application-stuff/*';
@import 'bootstrap';
body {
  ...
}

My application.js is

//= require rails-ujs
//= require jquery
//= require activestorage
//= require turbolinks
//= require jquery3
//= require popper
//= require bootstrap-sprockets
//= require_tree .

Hints

After trying by commenting out excerpts of code and restarting, I came to the conclusion that the culprit is require 'autoprefixer-rails from engine.rb. However, I could not figure out why but when commenting this line, I can successfully load my pages with bootstrap.

Comments

My issue seems to be different from https://github.com/twbs/bootstrap-rubygem/issues/164, hence a different issue

After seeing https://github.com/twbs/bootstrap-rubygem/issues/162, just in case, I have Node v11.1.0 with NPM 6.4.1

Facing the same issue. Tried installing node, but still it's giving error

Solution: After installing node, I removed duktape from my Gemfile and restart the rails server. it started working. It's working fine now

As long as you're not using duktape (Evaluating JS in your ruby files), you're good using this bootstrap gem.
