Tailwind CSS 类 不适用于 React，错误 "You need to enable JavaScript to run this app..."
Tailwind CSS classes is not working with React, error "You need to enable JavaScript to run this app..."
Talwind CSS 不支持 React。我已经按照文档 (https://v1.tailwindcss.com/docs/installation) 安装了 Tailwind CSS，我的代码如下。
有人可以帮助我吗？

这是我的 package.json 文件

}
}
下面是我的postcss.config.js
module.exports = {
plugins: {
tailwindcss: {},
autoprefixer: {},
},
}
下面是我的tailwind.config.js
module.exports = {
content: [
"./src/**/*.{js,jsx,ts,tsx}",
],
plugins: [
// ...
require('tailwindcss'),
require('autoprefixer'),
// ...
]
}
后来，我编辑了我的 index.js
import React from "react";
import ReactDOM from "react-dom";
import App from "./App";
//const App = require("./App");
ReactDOM.render(
<App title="Heyy React Dev Tool"/>, document.getElementById("root")
);
我也像下面这样编辑了我的 App.js
import React from "react";
import "./assets/css/style.css"
function App({title}) {
return (
<div>
<div className="bg-gray-600 text-white p-5 border">{title}</div>
</div>
);
}
export default App;
最后但现在至少这些是我的 style.css 文件已生成

我查看了您的存储库：即使您说您关注了 the guide，您也没有关注。问题归结为没有真正正确地遵循文档。
您的 tailwind.config.js 文件中缺少此行，这导致 tailwind 无法检测到您所有 .js 文件中的 class 用法：
module.exports = {
// You are missing this block that defines what files tailwind should scan for usage
content: [
"./src/**/*.{js,jsx,ts,tsx}",
],
theme: {
extend: {},
},
plugins: [],
}
添加此行后，您的 CSS 应该可以正确构建：
您没有正确遵循指南的其他迹象：
tailwindcss 被列为依赖项而不是 devDependency- 您的
tailwind.config.js 文件似乎已过时。您确定 运行 npx tailwindcss init 正确吗？您确定您确实是 Tailwind CSS 的 运行 v3 吗？
检查你的 index.js 文件你需要导入 ReactDom porperlt 并像这样正确使用它
从“react-dom”导入 ReactDom；
还有这个
从“react-dom”导入 ReactDom；
Talwind CSS 不支持 React。我已经按照文档 (https://v1.tailwindcss.com/docs/installation) 安装了 Tailwind CSS，我的代码如下。
