Angular9/Typescript3.8/Babylon4.1.0 - Typescript 編譯錯誤 - 找不到模塊'react'/找不到命名空間'JSX'

Question

我目前在 angular9 應用程序的上下文中面臨Babylon4.1.0的編譯問題。 檢查員似乎無法導入內部使用的"react"模塊。 可以通過以下方式重現該問題 * 使用 CLI 創建引導 angular9 應用 * 將 @babylon/* 依賴項添加到package.json * 添加import '@babylonjs/inspector'; 到app.component.ts

我在tsconfig.json中使用了幾個module和target設置，但沒有運氣。 坦率地說，我在這里也有點無能為力，因為我認為npm應該已經下載了所需的依賴項（如react ） 。 任何想法可能導致問題？

---

這是相關文件，但如前所述，這基本上只是一個新引導的准系統 angular9 應用程序。 用於重現問題。 設置幾乎都是出廠默認設置。

app.component.ts ：

import { Component } from '@angular/core';
import { OnInit } from '@angular/core';

import '@babylonjs/inspector';  // causes compilation error

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit{
  title = 'angular9-babylon41';

  ngOnInit() {
    console.log(`Test`);
  }
}

Answer 1

該解決方案由BabylonJS核心開發人員提供。 在BabylonJS 論壇中。 基本上：

• 在 BabylonJS 的4.1.0版本中， @types/react和@types/react-dom依賴。 不知何故迷失在框架要求中。
• 將它們手動添加到package.json devDependencies可以為客戶端修復此問題。
• BabylonJS 可能會在未來的某個版本中修復這個問題，並且 deps. 將再次添加。

Answer 2

使用 Babylon 4.0.3時，錯誤有所不同，其他一切與上述相同：（與此相反，Babylon4.0.3、Angular8 和 TS 3.5 的組合在過去一直有效） 。
