This is probably and error with the stylesheet_link_tag and stylesheet_pack_tag, check out your layout files probably you are including sass files and you are using stylesheet_link_tag, this is breaking your code given that as I understand you can just link plane css files. so if you are including sass files use the stylesheet_pack_tag

The root of the problem seems to be bundler. What operating system and Ruby version are you using? It may be a problem with old OpenSSL library, so you can not install bundler and everything after it.

If you are using jRuby (your gem list output tells so), your problem seems to be the same as described in link. And there is a solution as well.

Maybe you forgot to set 2.1.2 version of ruby as global? (rbenv set global 2.1.2)

You just shared the Gem file, but nothing how this app is developed, so it is insufficient information to give you an accurate response. But usually, two different methods are followed.

Two separate application, as your ruby on rails application working, can create another react application, and consume all endpoints present in your Ruby on Rails application, if you could not find some require endpoint, you can check already made endpoints and make few new one following the way. Hopefully, it would be easier to do.

In this method, you have to break apart your project and removing all Angular Gems already present in your project and start with fresh frontend with ReactJS. In my opinion, it requires much more Ruby on Rails knowledge to do it, but in the end, you will get just one project.

As from Gem file seem it is heavily using Angular, so probably you have run it and check if it has most of the Endpoints made Restful. If yes then I suggest to go on method one and create new ReactJS app, which will consume all endpoint made in Ruby on rails, that would be more work on React side app and less on Ruby on Rails. Even if you found that some endpoints are not present you can follow already created endpoints coding and action, where you will complete details. I understand there will be two different projects, but the learning curve to learn Ruby on Rails and integrating it with React would be more than having two different projects.

I solved this issue by also upgrading mongoid dependecies.

Apparently, Kaminari 1.0.1 is not compatible with mongoid-audit 1.0.2

I think other gems are depedent on Nokogiri, so try bundle update.

bundle update will resolve a dependency tree and try and install versions that satisfy all the other gems dependencies.

There was a Javascript error, specifically, I needed to include Tether to use Bootstrap. On local there is no minification, so even with an error, Vue.js was working. But on Production, one JS error would completely stop the whole application JS compiling.

Making sure I have that dependency fixed the problem.
