反應，和/ AFRAME對象分配錯誤

在嘗試掛鉤AFRAME內反應本地的，但在仿真器啓動時，我得到這個錯誤：反應，和/ AFRAME對象分配錯誤

One of the sources for assign has an enumerable key on the prototype chain. Are you trying to assign a prototype property? We don't allow it, as this is an edge case that we do not support. This error is a performance optimization and no spec compliant.

我使用AFRAME 0.5.0和應對本土0.41.2

錯誤從polyfills.js的第56行拋出，並且涉及到aframe-master.js：55729的這一部分。

Object.assign(THREE.MTLLoader.prototype, THREE.EventDispatcher.prototype, {

有沒有辦法解決這個問題？我是否需要修改框架以使用不同的任務，或者有什麼方法可以解決這個問題？

我正在運行一個非常簡單的Hello World，它只是試圖加載依賴關係失敗。在其他相關的問題上，人們說他們已經通過使用lodash.assign或Object.defineProperties來解決它 - 這是一個可行的解決方案嗎？在此期間，我可以恢復到較早版本的react-native，但我最好喜歡使用最新的a-frame。

**更新** 好吧，我試着回滾，安裝反應母語0.36.1和交換我加載在WebView中來AFRAME使用0.3.2網站。

我在陣營本機應用程序的代碼是這樣的：

好吧，我試着回滾，安裝使用rninit反應本地0.36.1和交換我加載在WebView中來AFRAME使用本網站0.3.2。

我在陣營本機應用程序的代碼是這樣的：

import React, { Component } from 'react'; 
// import ReactDOM from 'react-dom'; 
import { 
    AppRegistry, 
    WebView 
} from 'react-native'; 

export default class test4 extends Component { 
    render() { 
    return (
     <WebView source={{uri: 'http://[theurl]/test.html'}}/> 
    ); 
    } 
} 


AppRegistry.registerComponent('test4',() => test4);

的AFRAME應用程序是這樣的：

<!DOCTYPE html> 
<html> 
    <head> 
     <title>A-Frame walkthrough (final)</title> 
     <script src="/aframe.js"></script> 

    </head> 
<body> 
    <a-scene> 
    <a-assets> 
     <img id="circle" src="circle.png"/> 
    </a-assets> 


     <a-sky src="Ephesus4_1.jpg" rotation="0 -130 0"></a-sky> 
    </a-scene> 

</html>

當我從Chrome檢查的WebView打開調試器：//檢查＃設備，我得到這個輸出：

任何建議，將不勝感激！

com.facebook.react.common.JavascriptException：

我也是在Android模擬器本身得到這個{ 「堆疊」：「錯誤：未能執行的 'WorkerGlobalScope' importScripts」：該在http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false&minify=false「腳本加載失敗。\ n在executeApplicationScript（http://localhost:8081/ebuggerWorker.js:207）\ n在的onMessage（http://localhost:8081/debuggerWorker.js:38.5）」}

我得到即使我切換到web視圖加載非AFRAME網站同樣的錯誤。

嗨Toby，你能發佈reactjs和aframe的版本嗎？ –

Yep Aframe 0.5.0和React-native 0.41.2已添加到問題 –

我的成功部署使用了框架0.3.2和React-native 0.36.1。我建議你降級測試。同樣基於你的研究，這個問題似乎更多地涉及反應原生的結局。你有沒有嘗試在你的應用中加載原生webview而不是反應？ –

經過大量的搞亂之後，我發現我的很多問題是由於試圖在模擬器中測試。

在設備上運行時，我能夠獲得運行最新版本的react-native的最新版本的應用程序，但只能通過設置react-native來從源代碼重新編譯android項目，從當前的主人拉。我不得不在Android.Manifest中啓用硬件加速。

感謝Chris Chen的幫助
