javascript - NextJs Tailwind build (purge) 移除所有样式

Question

在我当前的 NextJS 项目中，我使用 Tailwind 作为 CSS 框架。当我运行 yarn dev ，一切正常，但每当我运行 yarn build后跟 yarn start ，我的所有 CSS 似乎都被清除了，因为我的页面布局完全不同。

后:

我的 tailwind.config.js 文件:

    /* eslint-disable global-require */

const defaultTheme = require('tailwindcss/defaultTheme');

module.exports = {
  purge: ['./pages/**/*.{js,ts,jsx,tsx}', './components/**/*.{js,ts,jsx,tsx}'],
  darkMode: false, // or 'media' or 'class'
  theme: {
    screens: {
      sm: '640px',
      md: '768px',
      max_md: { max: '767px' },
      lg: '1024px',
      xl: '1536px',
    },
    colors: {
      primary: '#f2a53f',
      white: '#fff',
    },
    fontFamily: {
      title: ['Dancing Script', 'Times New Roman', 'sans-serif'],
      sans: ['Roboto', ...defaultTheme.fontFamily.sans],
    },
    textShadow: {
      default: '1px 1px 3px #000',
    },
    zIndex: {
      1: -1,
    },
    extend: {
      height: {
        128: '32rem',
      },
      margin: {},
    },
  },
  variants: {
    extend: {},
  },
  plugins: [require('tailwindcss-textshadow')],
};

postcss.config.js 文件:

const purgecss = [
  '@fullhuman/postcss-purgecss',
  {
    content: [
      './pages/**/*.{js,jsx,ts,tsx}',
      './components/**/*.{js,jsx,ts,tsx}',
    ],
    defaultExtractor: (content) => content.match(/[\w-/:]+(?<!:)/g) || [],
  },
];

module.exports = {
  plugins: [
    'tailwindcss',
    process.env.NODE_ENV === 'production' ? purgecss : undefined,
  ],
};

_app.tsx:

import Head from 'next/head';
import { ApolloProvider } from '@apollo/client';
import { AppProps } from 'next/app';
import { useApollo } from '../../apollo/client';

import '../styles/globals.css';

const MyApp = ({ Component, pageProps }: AppProps) => (
  <ApolloProvider client={useApollo(pageProps.initialApolloState)}>
    <Component {...pageProps} />
  </ApolloProvider>
);

export default MyApp;

globals.css:

@tailwind base;
@tailwind components;
@tailwind utilities;

@font-face {
  font-family: 'Dancing Script';
  font-style: medium;
  font-weight: 500;
  font-display: swap;
  src: local('Dancing Script'),
    url(/fonts/DancingScript-Medium.tff) format('tff');
}
body {
  margin: 0 !important;
}

如果有任何问题，请随时告诉我。我在网上查看了其他问题，但没有找到解决我的问题的方法。

仔细检查 tailwind.config.js 中的路径.如果您的组件不在 components目录，则需要更新 purge反射(reflect)这一点的路径。
