npm install postcss-px-to-viewport --save-dev yarn add postcss-px-to-viewport --save-dev pnpm add postcss-px-to-viewport --save-dev
如果devserver正在運行，安裝完成以后記得重啟devserver。
在項目根目錄下創建 postcss.config.js 文件，并填入一下內容：
module.exports = {
plugins: {
// ...
'postcss-px-to-viewport': {
// options
unitToConvert: "px",
viewportWidth: 1920,
viewportHeight:1080,
unitPrecision: 3,
propList: [
"*"
],
viewportUnit: "vw",
fontViewportUnit: "vw",
selectorBlackList: [],
minPixelValue: 1,
mediaQuery: false,
replace: true,
exclude: /(\/|\\)(node_modules)(\/|\\)/,
}
}
}重新運行，打開瀏覽器查看屬性值已經變為vw計算，就是這么簡單。
