Sprockets::FileNotFound at / couldn't find file 'react-server' with type 'application/javascript'

Question

I'm returning to a website that I made about a year and a half ago, and when spinning up the rails server, I get this error:

Sprockets::FileNotFound at / couldn't find file 'react-server' with type 'application/javascript' Checked in these paths: [bunch of file paths...]

The errors looks the same as this issue: rails web pack react - sprocket couldn't find file react-server

The previous post talks about removing old react rails files, but I don't know which files that would be referring to.

In the end, it was one installation and one gemfile addition that did the trick. I ran: npm install --save react-server, and then I added: gem 'react-rails', to my gemfile, then of course ran bundle exec install.

In the file server-rendering.js delete or comment those lines:

//= require react-server
//= require react_ujs
//= require ./components
