I'm not sure why im getting this. If I changed 'application' back to 'default' I no longer get the error but the CSS does not show up on the webpage. This is my first Ruby On Rails project so I would appreciate any help.
ExecJS::ProgramError in Welcome#index
Showing C:/Users/Michael/Projects/dot/app/views/layouts/application.html.erb where line #5 raised:
TypeError: Object doesn't support this property or method
Rails.root: C:/Users/Michael/Dropbox/Docs/Homework/Projects/dot
app/views/layouts/application.html.erb:5:in `_app_views_layouts_application_html_erb__35629208_74953452'
Missing semicolon (if you've ever done PHP, it would be one of the first things you'd look for):
#title{
color: #0b1e40;
}
Looking around, the error you have seems to be this:
Object doesn't support this property or method Rails.root
This suggests a problem with your routes:
#config/routes.rb
root "welcome#index" #-> you don't need (get "welcome#index")
--
You may also have an issue with ExecJS (the class which runs javascript on your system) -- if you're using Windows, you should download nodeJS, install and run it, restarting your rails server in the meantime.
This should solve the problem with calling application vs default in your layout.
There is syntax error in your welcome.scss
you forgot the ;
#title{
...
color: #0b1e40;
...
}
Maybe this helps you... (if you use rails on windows)
How to fix error
Navigate to \app\views\layouts\application.html.erb
Change line 6 from
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
to
<%= javascript_include_tag 'defaults', 'data-turbolinks-track' => true %>
And you’re done!
i found it on next url
http://mech.xyz/how-to-fix-ruby-on-rails-turbolinks-js-coffee-error-windows/
Use the assets pipeline. Just place your Welcome.scss into app/assets/stylesheets. Remove <%= stylesheet_link_tag "welcome.scss" %>

//= require jquery3
//= require popper
//= require bootstrap-sprockets
//= require turbolinks
//= require_tree .
4) I got an error in the application.html.erb file so i changed "application" in the two lines to "application.scss" and "application.js" and then i installed Node.js

</head>
<body>
<%= yield %>
</body>
</html>
I did Bundle Install and reset the server. Then nothing happen to the homepage, the font didn't change...
Thank for your help
Ok now i have this, it seem that bootstrap is not displayed totaly
Bootstrap has been installed successfully you however need to create an HTML page to leverage that new CSS you have.
Run this in your terminal to make your own custom page.
rails generate controller home index
You can now update the app/views/home/index.html.erb file to contain whatever Bootstrap styled HTML you want.
The last step in order for you to view your page would be to modify the routes.rb file.
In that file, add the line root 'home#index' to see your new page when you visit your Rails app.

Here is what I am getting when trying to add a navbar to my webpage:
The problem is you're not requiring application.scss and application.js.
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true%>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
If you are getting the Object does not support the property or method error, then use the latest gem for "coffee-script-source" (like 1.10.0) - anything other than version 1.9.x.
Add the following line to Gemfile, run bundle install and restart the server.
gem 'coffee-script-source', '~> 1.11', '>= 1.11.1'
I finally got this to work. this link provided me with my solution. Thanks to everyone who helped me on this post, it was greatly appreciated and a great learning experience :)
I am new to ruby on rails and started learning in a french website called openclassroom. So in the instructions it tells me to create an html page using this command:
$ rails g controller pages home #we are launching our webpage
$ rails server #we launch our server
When I try accessing http://locahost:3000/pages/home it gives me an error. The screen looks like this...

You should not remove the application.css manifest file. You should, however, change it's name to application.css.scss. This way it can be preprocessed by SASS.
If you are including the imports for bootstrap in a separate file as you do in your example (custom.css.scss), you must ensure that this file are included in the application manifest. The require_tree directive that is included by default does this (you need to have the file located in the /stylesheets directory, like you do):
#application.css or application.css.scss
*= require_tree .
However, since you are using SCSS, I recommend the following approach:
#application.css.scss
#...
#all your files and directives
#...
#import "bootstrap-sprockets";
#import "bootstrap";
This way, it is not necessary to have a separate file like custom.css.scss
