I've npm installed the latest node-sass, and scss files work fine until I use #use. I have a _tokens.scss file in /shared/tokens/ folder. Within _tokens.scss I have:
$colorwhite: #ffffff;
In my root folder, my App.scss looks like this:
#use "shared/tokens/tokens";
.App-header {
color: tokens.$colorwhite;
}
But I am getting this error:
./src/App.scss (./node_modules/css-loader/dist/cjs.js??ref--6-oneOf-5-1!./node_modules/postcss-loader/src??postcss!./node_modules/resolve-url-loader??ref--6-oneOf-5-3!./node_modules/sass-loader/dist/cjs.js??ref--6-oneOf-5-4!./src/App.scss)
SassError: Invalid CSS after " color: tokens": expected expression (e.g. 1px, bold), was ".$colorwhite;"
on line 26 of /Users/xxx/src/App.scss
>> color: tokens.$colorwhite;
Any ideas?
Edit: it works fine with #import. I've also tried #use... as * but no-go.
Update:
Since Node Sass is now deprecated, you can migrate to Dart Sass by replacing node-sass with sass in your package.json and so you will be able to use the #use and #forward rules.
You can use the migration tool to help you with the update.
Original answer:
The #use rule is currently only supported by Dart Sass. You should use #import instead.
You could switch to Dart Sass by taking advantage of package-aliasing. I guess this will not work under yarn.
First you remove the current node-sass pkg, then run:
npm install node-sass#npm:sass.
And you are fit to use the full features from sass with some remarks though.
Check the behavioral diffs here.
The performance measurement indicates that dart-sass is slower than node-sass.
It's all up to you and this turns to be a valid option here, if you really want to use these features provided by Sass.

I'm upgrading an old system with many of these:
#import "~bootstrap/scss/mixins";
That fails when compiling with the dart-sass CLI.
I used to use node-sass, and packages like node-sass-tilde-importer and node-sass-package-importer to help with that syntax. They don't seem to work for dart-sass.
Given that I'm now using the dart sass CLI, how do I deal with this?
The solution is simple, but unfortunately does not support the tilde syntax.
The scss file should have this:
#import "foo/bar"; // <--- must remove tilde
And the cli syntax is:
sass --load-path=path/to/node_modules SomeFile.scss SomeFile.css
For completeness, the obvious other solution is:
#import "../../../node_modules/foo/bar";
Dart Sass CLI? I think there is no way to import like this in Dart Sass. You have to do it manually.
But there is a Sass migrator to fix legacy sass code, give it a try :
https://sass-lang.com/documentation/cli/migrator
If you are using it with module bundlers, this might help:
How to import sass using tilde prefix with webpack, sass-loader and dart sass
this is a strange error that I don't understand at all. I usually search and seek the answer before posting it on StackOverflow. So the problem is that I would like to use the variables that I imported from another scss file called _variables.com using #use. This is written in scss-lang.com#use. The way I try to use my variable:
_variables.scss
$secondary-color: #CEA44A;
style.scss
#use '../../variables';
.foo {
background-color: variables.$secondary-color;
}
// ERROR TEXT
Invalid CSS after "...olor: variables": expected expression (e.g. 1px, bold), was ".$secondary-color;"
on line 19 of sass/c:\Users\Amirreza Amini\Desktop\blog\src\Components\Register\Register.scss
background-color: variables.$secondary-color;
Use Live Sass Compiler by Glenn Marks
I had exactly the same problem. You read about #use on SASS official website, follow the instructions, write the code in Visual Studio Code and then you get this strange Compilation Error when saving the SASS or SCSS file. You double check everything and it seems like it should work but it doesn't.
Well, the problem is caused by the Visual Studio Code extension you are using for compiling SASS or SCSS files to CSS files.
Don't use this extension: Live Sass Compiler by Ritwick Dey
You are probably using this extension: Live Sass Compiler by Ritwick Dey.
It's widely used, but no longer supported by the author. Consequently, the SASS version isn't updated. This extension produces the error you are describing as you can see below.
Use this extension: Live Sass Compiler by Glenn Marks
You should use this extension: Live Sass Compiler by Glenn Marks. As the author states: A big thank you to #ritwickdey for all his work. However, as they are no longer maintaining the original work, I have released my own which has built upon it. This extension compiles your SASS or SCSS files to CSS files successfully as you can see below.
change #use '../../variables'; to #use '../../variables' as *;
I've been using Compass to compile Sass in my project, but it is now deprecated and no longer maintained so I want to move away from using Compass. The project uses PHP and Laravel, so I would like to use Laravel Elixir for compiling the Sass files instead.
Is there a way to transfer my .scss files from Compass to Elixir without going in and changing all the places in my Sass code that I use Compass helpers, or do I need to more or less re-write my Sass files? There are a ton of them, so I would love to avoid that.
On the suggestion of my co-worker, what I tried was to add the compass files to my resources/assets/sass directory (includes compass/css3, compass/layout, compass/reset, compass/typography, and compass/utilities, as well as several other .scss files included in Compass. The hope was that by including these files, the functions of Compass would still apply outside of it.
When I try to compile with gulp, the error I'm currently getting (although I'm guess I'll run into another one once this is fixed) is:
>> Sass Compilation Failed: resources/assets/sass/compass/_support.scss
Error: Undefined operation: "prefix-usage(browser-prefixes(browsers()), css-transitions, (full-support: true), (partial-support: true)) gt 0.1".
on line 324 of resources/assets/sass/compass/_support.scss
>> #if $usage > $threshold {
------^
My guess is that I will need to go ahead and remove the Compass stuff from the Sass code manually, but I'm hoping someone else has a better solution for me! Thanks.
If i have a fairly large document in SCSS, and somewhere i missed the closing tag, is there any program or service or output (console log) code to check where is the missing closing tag?
(Im using SASSY with drupal PHP preprocessor)
The sass binary built in to the actual Sass library will report syntax errors.
$ cat broken.scss
html {
display: block;
.orange {
color: orange;
}
$ sass broken.scss
Syntax error: Invalid CSS after "}": expected "}", was ""

Use --trace for backtrace.
You can install sass with gem install sass as long as Ruby is installed. That will install the latest version of sass.
If you don’t already have Ruby installed, just install it on your development machine. On Windows, use the RubyInstaller. On Mac, use the built-in old version of Ruby, or install a newer version with Homebrew using brew install ruby. On Linux, search for “ruby” in your package manager.
If you mean that you want a program to tell you “the closing } you’re missing should go between color: orange; and }, I doubt there is one. Deciding exactly where the } would require making assumptions about indentation and other formatting of the code, so any program someone has written for that probably only works with their code. In the example code, there is no general and automatic way to tell if color: orange; was supposed to be inside .orange or inside html.
I created a project using yo webapp (with the generator-webapp installed obviously).
Everything is fine, but I'm still missing something. I'm sure it's such an easy answer that I'll never come back to SO because I'll be too embarrassed.
I want to use Compass, which comes out of the box with Yeoman, but I don't know how. I mean, obviously #import "compass...etc" inside any Sass files won't work since inside app/bower_components (the default path for Sass #imports specified inside Gruntfile.js) there's no compass directory.
What should I do now in order to import Compass stylesheets?
You can use compass just as you would usually do. If you set up a vanilla compass project with compass create, there is compass folder either. If you want to use any of the helpers compass ships with, you can import them just as described in the documentation, e.g.
#import "compass/css3";
.mybox {
#include box-shadow(red 2px 2px 10px);
}
main.scss
You would have to install grunt task for compass with npm install grunt-contrib-compass and adjust your Gruntfile.js to add a task for compass compilation.
It may appear not that easy since it has some tricky parts like to compile your sass to .temp/main.css to use for testing/livereload, and then minify it into your dist when doing final build.
The most easy way might be to just try another generator that has compass in a separate directory. For example angular generator has compass and even bootstrap for compass. It's pretty cool.
