我可能是从网上的一堆博客文章中拼凑出来的。一些博客使用autoprefixer，一些使用postcss-preset-env&这都是混乱。

我已tailwindcss作为开发依赖项安装并在pages/_app.tsx. 这是我的相关文件：

tailwind.config.js

const defaultTheme = require('tailwindcss/defaultTheme')

module.exports = {
    future: {
        removeDeprecatedGapUtilities: true,
        purgeLayersByDefault: true,
    },

                        content = mdx.sync(content)

                        // Capture as liberally as possible, including things like `h-(screen-1.5)`

                        // Capture classes within other delimiters like .block(class="w-1/2") in Pug
                        const innerMatches =

                        return broadMatches.concat(innerMatches)
                    },
                },
            ],
        },
    },
    theme: {
        extend: {
            colors: {
                'accent-1': '#333',
            },
            fontFamily: {
                sans: ['Inter var', ...defaultTheme.fontFamily.sans],
            },
        },
    },
    variants: {},
    plugins: [
        function ({ addBase, addComponents, theme }) {
            addBase([
                {
                    '@font-face': {
                        fontFamily: 'Inter var',

                        fontNamedInstance: 'Regular',
                        fontDisplay: 'swap',
                        src: 'url("/fonts/Inter-roman.var-latin.woff2?3.13") format("woff2")',
                    },
                },
                {
                    '@font-face': {
                        fontFamily: 'Inter var',
                        fontWeight: '100 900',

                        src: 'url("/fonts/Inter-italic.var-latin.woff2?3.13") format("woff2")',
                    },
                },
            ])
        },
    ],
}

postcss.config.js

module.exports = {
    plugins: [
        'tailwindcss',
        'postcss-flexbugs-fixes',
        process.env.NODE_ENV === 'production'
            ? [
                    '@fullhuman/postcss-purgecss',
                    {
                        content: ['./pages/**/*.{js,jsx,ts,tsx}', './components/**/*.{js,jsx,ts,tsx}'],
                        defaultExtractor: (content) => content.match(/[\w-/:]+(?<!:)/g) || [],
                    },
              ]
            : undefined,
        [
            'postcss-preset-env',
            {
                autoprefixer: {
                    flexbox: 'no-2009',
                },
                stage: 3,
                features: {
                    'custom-properties': false,
                },
            },
        ],
    ],
}

我确定我做错了什么，但不知道是什么？

找到了解决方案。

我从以下内容中删除了整个内容postcss.config.js：

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