我使用 node-sass 将我所有的 Sass 文件编译为 master.css。这很好用，但现在我想添加前缀。我只想使用 npm，不使用 Gulp 或 Grunt。

这是我的 package.json 文件：

{
  "name": "xxxxxx.com",
  "version": "1.0.0",
  "description": "",
  "watches": {
    "sass": "src/scss/**"
  },
  "scripts": {
    "sass": "node-sass src/scss/master.scss -o dist/css/ --style compressed",
    "prefix": "postcss --use autoprefixer dist/css/master.css -d dist/css/master.css",
    "dev": "rerun-script"
  },
  "author": "Jan",
  "license": "ISC",
  "devDependencies": {
    "autoprefixer": "^6.3.1",
    "browserify": "^13.0.0",
    "clean-css": "^3.4.9",
    "node-sass": "^3.4.2",
    "postcss-cli": "^2.5.0",
    "rerun-script": "^0.6.0",
    "uglifyjs": "^2.4.10"
  }
}

我不让它运行。我使用 autoprefixer 和 postcss-cli。模块已本地安装在项目目录中。我认为我的“脚本”部分是错误的。那怎么看才对？

        "prebuild:js": "npm run lint",
        "build:watch": "watch 'npm run build' src/*"
    }
}

您需要 postcss 和 postcss-cli 作为 devDependency。

Sass 与 Node Js（使用 Autoprefixer）

npm i -D autoprefixer clean-css-cli node-sass postcss-cli

{
  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {
    "autoprefixer": "^9.5.1",
    "browserslist": "^4.5.4",
    "clean-css-cli": "^4.3.0",
    "node-sass": "^4.11.0",
    "postcss": "^7.0.14",
    "postcss-cli": "^6.1.2"
  },
  "devDependencies": {},
  "scripts": {
    "clean": "rimraf scss",
    "compile": "node-sass --output-style=expanded --source-map=true css/scss/main.scss css/scss/main.css",
    "prefix": "postcss css/scss/main.css --use=autoprefixer --map=false --output=css/scss/main.css",
    "minify": "cleancss --level=1 --source-map --source-map-inline-sources --output css/scss/main.min.css css/scss/main.css",
    "dev": "npm run compile -- --watch",
    "build": "npm run clean && npm run compile && npm run prefix && npm run minify",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "browserslist": [
    "last 4 version"
  ],
  "author": "",
  "license": "ISC"
}

终端命令构建：npm run build

假设我们在sass目录中有styles.sass文件。我用过这样的东西（我的 package.json）：

{
 "scripts": {
    "c":"node-sass sass/styles.sass -o .|postcss styles.css -u autoprefixer -r",
    "w":"watch 'npm run c' sass"
 }
}

终端命令：npm run w. 此时每次保存styles.sass文件都会自动生成编译后的styles.css文件。我在全球范围内安装了 postcss-cli、node-sass 和 watch 包。
