After update from Angular 8 to Angular 9, 'ng generate component' generates a .css file instead of .scss

Just to clarify the already accepted answer: As of Angular 9+ , I've fixed it in 'angular.json' file as follows: I've added/updated 'schematics' option as shown below

  "projects": {...},
  "schematics": {
    "@schematics/angular:component": {
      "style": "scss"
    }
  },

Open a new command-line interface and run the following command:

$ git clone https://github.com/techiediaries/angular-portfolio

Next, navigate to your project's folder and install the project's dependencies using the following commands:

$ cd angular-portfolio
$ npm install

Head back to your command-line interface and run the following command:

$ ng version

You'll get the following output:

Your global Angular CLI version (9.0.0-rc.2) is greater than your local
version (7.1.4). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".

Update: Working without IVY, but I want IVY for ng build --configuration=default but ng serve entryComponents error with;

"angularCompilerOptions": {
    "enableIvy": false
  }

Please, can you help me with a more complete example of angular.json file? (According with the documentation https://angular.io/guide/i18n#localize-config for Angular 9).

"projects": {
  ...
  "projectName": {
    "i18n": {
      "sourceLocale": "en",
      "locales": {
        "en": "src/locale/default.xlf"
      }
    }
   "configurations": {
      "default": {
          "localize": ["en"],
      }
    }
}

A minimal XLIFF document with one entry looks something like this:

<?xml version="1.0"?>
<xliff version="1.2">
<file source-language="EN" datatype="plaintext" original="file.ext">
<body>
<trans-unit id="1">
<source>Hello World!</source>
</trans-unit>
</body>
</file>

I still have this problem using angular 9.06 and using this angular.json file:

{
  ...
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "version": 1, 
  "newProjectRoot": "projects",
  "projects": {
      "i18n": {
        "sourceLocale": "en-US",
        "locales": {
          "fr": "src/locale/messages.fr.xlf"
        }
      },
      "architect": {
        "build": {
          "configurations": {
            ...
            "fr": {
              "localize": ["fr"]
            }
          }
        }
}
