SASS Problem with npm scripts ( autoprefix and postcss )

My compilation process does not work and as I am a beginner I do not know why. Any constructive help is highly appreciated ;).

I have spent like 24 hours to solve the problem without success... I have reinstalled all packages, cleaned cache etc., but nothing has helped.

     {
  "name": "natours",
  "version": "1.0.0",
  "description": "Landing page for natours",
  "main": "index.js",
  "scripts": {
    "watch:sass": "node-sass sass/main.scss css/style.css -w",
    "devserver": "live-server",
    "start": "npm-run-all --parallel devserver watch:sass",
    "compile:sass": "node-sass sass/main.scss css/style.comp.css",
    "concat:css": "concat -o css/style.concat.css css/icon-font.css css/style.comp.css",
    "prefix:css": "postcss --use autoprefixer -b 'last ten versions' css/style.concat.css -o css/style.prefix.css",
    "compress:css": "node-sass css/style.prefix.css css/style.css --output-style compressed",
    "build:css": "npm-run-all compile:sass concat:css prefix:css compress:css"
  },
  "author": "Jonas",
  "license": "ISC",
  "devDependencies": {
    "autoprefixer": "^10.0.0",
    "concat": "^1.0.3",
    "libs": "^0.1.2",
    "node-sass": "^4.14.1",
    "npm-run-all": "^4.1.5",
    "postcss": "^8.0.5",
    "postcss-cli": "^7.1.2"
  },
  "dependencies": {
    "live-server": "^1.2.1"
  }
}

When I run command npm run prefix:css I get such error:

npm run prefix:css

> [email protected] prefix:css /home/piotr/Documents/personal/ProgrammingBooks/HTML, CSS/advanced-css-course-master/Natours/starter
> postcss --use autoprefixer -b 'last ten versions' css/style.concat.css -o css/style.prefix.css

I ran into a similar issue - there seems to be some bugs with autoprefixer version 10.0.0.

Downgrade your autoprefixer vesion and your command will run as expected.

Change "autoprefixer": "^10.0.0", to "autoprefixer": "<10.0.0", in your package file. This will install the newest version of autoprefixer that is less than version 10.0.0 - reference.
