Angular CLI 7: Sass failed to compile

Question

few moments ago I installed Angular Cli 7 and started clean project by

ng new my-app

I selected precompiler SASS for css, but when I'm editing file styles.sass then is not working, my styles.sass looks like this

h1 { color: red }

but ng serve show this message

Failed to compile.

./src/styles.sass (./node_modules/@angular-devkit/build-angular/src/angular-cli-files/plugins/raw-css-loader.js!./node_modules/postcss-loader/src??embedded!./node_modules/sass-loader/lib/loader.js??ref--14-3!./src/styles.sass) Module build failed (from ./node_modules/sass-loader/lib/loader.js):

h1 { ^ Invalid CSS after "h1 {": expected "}", was "{" in /Users/a/Documents/angular-projects/my-app/src/styles.sass (line 1, column 5)

how to fix it? and why that's happen?

Answer 1

• The CLI offers a command line flag to change your style when creating a new project with ng new my-app --style=scss

• As you can see, the extension is .scss , not .sass (at least for the syntax you're using, which is LESS)

• You are missing a semicolon h1 { color: red; } h1 { color: red; }

• Remember to update your angular.json and component files accordingly if you don't reecreate a new project to resolve that

Answer 2

dude ... I think your sintaxe maybe be wrong, look at https://sass-lang.com/guide you shoulding use

h1
   color: red,
   align: center
   ...

Answer 3

Could be because you upgraded your node. Try installing node-sass

npm install node-sass

More details about node-sass on https://www.npmjs.com/package/node-sass

Had the same problem, tried everything including reinstalling all the packages and node itself and none of them helped.
Finally the project was cloned to D:\\somefolder instead of the Desktop where I was cloning before. Then it compiled without any issues and worked fine.
