vue3+vite+ts使用daisyui/tailwindcss

news 来源：原创 2025/6/22 6:39:37

vite创建vue3脚手架

npm init vite@latest myVue3 – --template vue

cd .\myVue3\

npm i

npm run dev

安装tailwindcss/daisyui

依赖安装

npm install -D tailwindcss postcss autoprefixer daisyui

npx tailwindcss init -p

这条命令将生成postcss.config.js(因为加了-p)和tailwind.config.js用户将特定指令翻译为最终css或者加入daisyUI插件

:::
danger
可能出现的情况及解决方案
npm error could not determine executable to run

npm error A complete log of this run can be found in:
说明版本冲突，降低tailwind版本
npm install tailwindcss@3.3.3 -D
若还是不行请自行查找其对应关系

:::

修改配置

./src/style.css

/* 全部替换或者添加 */
@tailwind base;
@tailwind components;
@tailwind utilities;

出现Unknown at rule @tailwindcss(unknownAtRules)
则

1、打开 vs code 设置；
2、搜索设置 css Unknown；
3、改成ignore；

./postcss.config.js

用于解析style.css文件的@tailwind指令

export default {
  plugins: {
    // 这是专门处理Tailwind的工具
    // 你写的那些 class="bg-blue-500" 都要靠它来翻译成真正的CSS代码
    // 它会把Tailwind的魔法语法变成浏览器能看懂的东西
    tailwindcss: {},

    // 这是专门给CSS加"马甲"的工具
    // 比如你写 display:flex，它会自动帮你补全：
    // -webkit-flex (给老版Chrome用)
    // -moz-flex (给老版Firefox用)
    // 这样你的网站在各种浏览器都能正常显示
    autoprefixer: {},
  },
}

./tailwind.config.js

/**
 * 这是Tailwind CSS的配置文件
 * 相当于你家的装修设计图
 * @type {import('tailwindcss').Config} <-- 这是TS类型提示，告诉编辑器这是Tailwind配置
 */
import daisyui from "daisyui"; // 把DaisyUI家具城搬进来

export default {
  // 告诉Tailwind去哪里找需要装修的房间（扫描哪些文件）
  content: [
    './index.html',          // 主卧室（入口文件）
    './src/**/*.{vue,js,ts,jsx,tsx}' // 所有其他房间（各种组件文件）
  ],
  
  // 装修风格定制（可以改颜色、间距等）
  theme: {
    extend: {}, // 这里空着表示用默认风格
  },

  // 请来的装修队（插件）
  plugins: [
    daisyui // 这是专门装DaisyUI家具的施工队
  ],
}

测试样式

<script setup lang="ts">
  const handleChangeTheme = () => {
    const html = document.getElementsByTagName('html')[0]
    const darkTheme = html.dataset.theme

    if (darkTheme === 'dark') {
      html.dataset.theme = 'light'
    } else {
      html.dataset.theme = 'dark'
    }
  }
