Can'；无法在npm脚本中正确配置Autoprefixer

我正在尝试配置PostSS Autoprefixer，但它不起作用。它应该在同一个“css”文件夹中输出新的

style.prefix.css

文件。请帮助我理解，我的npm脚本/设置有什么问题

这是我的package.json

{
  "name": "sb-demo-website",
  "version": "1.0.0",
  "description": "demo website",
  "main": "index.js",
  "scripts": {
    "sass": "node-sass-chokidar sass/main.scss css/style.css -w --recursive --skip-initial",
    "compile-sass": "node-sass-chokidar sass/main.scss css/style.comp.css",
    "prefix-css": "postcss css/style.comp.css -o css/style.prefix.css --use autoprefixer"
  },
  "repository": {
    "type": "git",
    "url": ""
  },
  "author": "tk",
  "license": "ISC",
  "bugs": {
    "url": ""
  },
  "homepage": "",
  "browserslist": "last 3 versions",
  "devDependencies": {
    "autoprefixer": "^10.0.0",
    "node-sass": "^4.14.1",
    "node-sass-chokidar": "^1.5.0",
    "postcss": "^8.0.5",
    "postcss-cli": "^7.1.2"
  }
}

下面是我运行脚本时的输出：

$ npm run prefix-css

> sb-demo-website@1.0.0 prefix-css C:\Users\tk\Documents\Study\web\css\demo1
> postcss css/style.comp.css -o css/style.prefix.css --use autoprefixer

非常感谢您提供的任何帮助

看起来最新的Autoprefixer v10.0.0现在就有点过时了。将其降级至9.8.6版解决了上述问题

我将此作为一个回答，以防其他人遇到类似的错误。
