一、创建package.json文件

{"devDependencies": {"autoprefixer": "9","postcss": "7","postcss-rem-to-responsive-pixel": "^5.1.3","tailwindcss": "npm:@tailwindcss/postcss7-compat","weapp-tailwindcss-webpack-plugin": "^1.6.8","webpack": "npm:webpack@webpack-4"}
}

二、打开终端 yarn / npm 安装依赖

三、创建 vue.config.js文件

// 为了 tailwindcss jit 开发时的热更新
if (process.env.NODE_ENV === "development") {process.env.TAILWIND_MODE = "watch";
}const {UniAppWeappTailwindcssWebpackPluginV4,
} = require("weapp-tailwindcss-webpack-plugin");/*** @type {import('@vue/cli-service').ProjectOptions}*/
const config = {//....configureWebpack: {plugins: [new UniAppWeappTailwindcssWebpackPluginV4()],},//....
};module.exports = config;

四、创建postcss.config.js文件

const path = require("path");module.exports = {plugins: [require("autoprefixer")({remove: process.env.UNI_PLATFORM !== "h5",}),require("tailwindcss")({config: path.resolve(__dirname, "./tailwind.config.js"),}),// rem 转 rpxrequire("postcss-rem-to-responsive-pixel/postcss7")({rootValue: 32,propList: ["*"],transformUnit: "rpx",}),],
};

五、创建tailwind.config.js文件

const path = require("path");
const resolve = (p) => {return path.resolve(__dirname, p);
};/** @type {import('@types/tailwindcss/tailwind-config').TailwindConfig} */
module.exports = {mode: "jit",purge: {content: [resolve("./index.html"),resolve("./pages/**/*.{vue,js,ts,jsx,tsx,wxml}"),],},darkMode: false, // or 'media' or 'class'theme: {colors: {white: '#ffffff',black: '#000000',main: '#333333',content: '#666666',muted: '#999999',light: '#e5e5e5',primary: {DEFAULT: '#4173ff'},success: '#5ac725',warning: '#f9ae3d',error: '#f56c6c',info: '#909399',page: '#f6f6f6'},fontSize: {xs: '24rpx',sm: '26rpx',base: '28rpx',lg: '30rpx',xl: '32rpx','2xl': '34rpx','3xl': '38rpx','4xl': '40rpx','5xl': '44rpx'}},variants: {},plugins: [],corePlugins: {preflight: false,},
};
//自定义配置

六、App.vue文件的style中引入tailwindcss

<style>/*每个页面公共css */@import "tailwindcss/base";@import "tailwindcss/utilities";
</style>
