Modul konnte nicht analysiert werden: Reserviertes Schlüsselwort „Schnittstelle' gefunden

Question

Ich versuche, eine gemeinsame Komponente zu schreiben rd-component, die einige gemeinsame Seiten enthält, die in allen Projekten verwendet werden. Wenn ich diese öffentliche Seite importiere, wird der Fehler angezeigt:

Module parse failed: The keyword 'interface' is reserved (15:0)

Ich habe ein minimal reproduzierbares Beispiel erstellt, bei dem es sich um eine einfache Komponente handelt, die eine öffentliche Seite verwendet:

import './App.css';
import React from 'react';
import Goods from "rd-component/src/component/good/Goods";

const Chat: React.FC = (props) => {

  return (<Goods></Goods>);
}

export default Chat;

Das ist Index.tsx:

import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
import './index.css';
import reportWebVitals from './reportWebVitals';
import Chat from './App';

const root = ReactDOM.createRoot(
  document.getElementById('root') as HTMLElement
);
root.render(
  <React.StrictMode>
    <Chat />
  </React.StrictMode>
);


reportWebVitals();

Das ist meine package.json mit allen Paketen:

{
  "name": "react-demo",
  "version": "0.1.0",
  "private": true,
  "config-overrides-path": "src/config/config-overrides.js",

    ],

      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"

    "customize-cra": "^1.0.0",
    "react-app-rewired": "^2.2.1"
  }
}

Dies ist die vollständige Fehlerausgabe beim Ausführen des Befehls npm run build:

> react-demo@0.1.0 build
> react-scripts build

默认情况下，TypeScript（或者可能是 create-react-app，如果您正在使用的话）不会从 node_modules 编译模块。

您的 Goods 组件似乎就是这种情况：

import Goods from "rd-component/src/component/good/Goods";

{
  "dependencies": {
    // ...
    "rd-component": "0.1.1"
  }
}

默认配置假设 node_modules 中的所有内容都已准备好供纯 JavaScript 项目使用。

因此，TypeScript 编写的库组件预计已被转换为 JavaScript。

话虽这么说，您仍然可以尝试一种简单的解决方法，其中包括在项目 src 中添加一个指向库源的 TypeScript 文件的符号链接。

IIRC，不幸的是，某些构建引擎“太”智能，甚至可以通过符号链接查看实际路径...在这种情况下，您必须手动将库包含在编译范围中。

当然，正确的解决方案是预编译您的库。
