编辑：此问题现已弃用，因为3.0.0版的tailwind可与react一起使用，而无需使用CRACO。
在JIT模式下尝试使用Tailwind和React时，我添加的类没有样式，即使在刷新页面后也是如此。我必须重新启动服务器才能使样式生效。
tailwind.config.js:

module.exports = {
    mode: "jit",
    purge: ["./src/**/*.{js,jsx,ts,tsx}", "./public/index.html"],
    ...
}

craco.config.js:

module.exports = {
    style: {
        postcss: {
            plugins: [require("tailwindcss"), require("autoprefixer")]
        }
    }
}

package.json:

    "name": "random-name",
    "version": "0.1.0",
    "private": true,
    "dependencies": {
        "@craco/craco": "^6.3.0",
