what is causing Less::Error 'Unrecognised input'? - ruby-on-rails

I'm following this answer about using yarn to set up semantic-ui with rails but get this vague error that says only Unrecognised input whenever I access localhost. The stack trace is short and the only clue it provides is to the stylesheet and javascript link tags in my application.html.erb head:
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
What does Unrecognised input mean, and what causes it?

who would win? many lines of code or one missing semicolon?
make sure you end your variable declarations with a semicolon.

JSON Parser Error Unexpected Token Error Rails

I recently cloned my Rails app, which was developed on Linux, to my Windows OS. There were a few errors, and I managed to fix most of them except this one. This error pops up when I try to access my page locally:
JSON::ParserError
419: unexpected token at ''
This is the code in question:
<head>
<title>DemoApp</title>
<%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<%= javascript_include_tag "ckeditor/ckeditor.js" %>
<%= csrf_meta_tags %>
I researched and couldn't find a straightforward solution to this. I had previously changed my runtimes.rb to 'UTF-8' so that it will run in Windows.
Any help is much appreciated.
It could be because of a BOM or a tabulation space, it happens to me when I try to paste inside Vim.

Errno::ENOENT in Devise::Sessions#new

I'm using rails 5 to create a Facebook clone as a project and I periodically get an 'Errno::ENOENT in Devise::Sessions#new' error sometimes when I start the local server. I haven't yet experienced the problem on my production server. The problem goes away once I refresh the page.
The extracted source code is below. The line that starts stylesheet_link_tag is highlighted.
<%= csrf_meta_tags %>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>

<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
it works for me..

How to remove Invalid CSS after "": expected "{", was ""

I restart my project after one month and get this error
Showing /home/abc/prij/app/views/layouts/application.html.erb where line #5 raised:
Invalid CSS after "...���������������": expected "{", was ""
ActionView::Template::Error (Invalid CSS after "...���������������": expected "{", was ""):
2: <html>
3: <head>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
6: <%= csrf_meta_tags %>
7: </head>
How I resolve this?
Something's very wrong with one of your asset files. Are you sure you're not including a non-css file in your application.css.scss?
I'd narrow it down by removing some of your requires from application.css.scss. Hopefully this will isolate the problematic code, but it's tough to say much without more information.

Bootstrap Gem Installation Issue

I have added the bootstrap-sass gem and have installed the bundle. I have gone to github and think I have followed the directions correctly to finish the install for ruby on rails. It doesn't appear to be making a difference however on my local site - no font/formatting changes have been made, even after the install.
I am using a PC, https://github.com/findingtheway/pin
Change your app/views/layouts/application.html.erb to this:
<head>
<title>Pin</title>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
</head>
Rails uses application by default you have default which is why bootstrap is not loading.
