角 IE11 不工作。获取 SCRIPT1002 语法错误

Question

试图让 Angular 在 IE 11 中工作。我已经尝试了我在网上找到的所有内容。

我收到以下错误：

SCRIPT1002：语法错误

文件：polyfills.js，行：2358，列：1

第2358行

class Disposable {

    /**
     * Frees internal resources.
     */

    dispose() {}

}

SCRIPT1002：语法错误

文件：scripts.js，行：424，列：35

第 424 行

let SoapService = SoapService_1 = class SoapService {
    constructor(servicePort, servicePath, targetNamespace) {
        this.debug = false;
        this.asynchronous = true;
        this.localName = false;
        this.servicePort = '';
        this.servicePath = '';
        this.serviceUrl = '';
        this.targetNamespace = '';
        this.envelopeBuilder_ = null;
        this.xmlResponseHandler_ = null;
        this.jsoResponseHandler_ = null;
        this.servicePort = servicePort;
        this.servicePath = servicePath;
        this.serviceUrl = servicePort + servicePath;
        if (undefined !== targetNamespace)
            this.targetNamespace = targetNamespace;
    }

SCRIPT1002：语法错误

文件：vendor.js，行：88，列：1

88号线

class AnimationBuilder {
}

SCRIPT1002：语法错误

文件：main.js，行：91422，列：35

91422行同上

    let SoapService = SoapService_1 = class SoapService {
        constructor(servicePort, servicePath, targetNamespace) {
....

我确实有一个肥皂连接，无论如何都无法在本地主机上工作。所以这可能不是问题

在 main.ts 中添加了这一行

/// <reference path= "../node_modules/typescript/lib/lib.es6.d.ts" />

在 index.html 中添加了这个脚本

<script src="/node_modules/core-js/client/shim.min.js"></script>

配置文件

我也有一个 tsconfig.app.json 和 tsconfig.spec.json

polyfills.js

/**

 * This file is divided into 2 sections:

 *
 * The current setup is for so-called "evergreen" browsers; the last versions of browsers that

Answer 1

对于遇到类似问题的其他人：

Angular 8 已经成为默认目标es2015而不是es5

您需要创建一个，tsconfig.es5.json以便您只能在开发模式下在 es5 上运行，但可以在此处找到更多信息：https : //github.com/angular/angular-cli/issues/14455

您还需要polyfills.ts根据您使用的内容取消注释 polyfill 。

对于其他人和提问者：

然后，您需要向 zone.js 添加一个标志

添加import './zone-flags.ts'; 之前import 'zone.js/dist/zone'; 然后zone-flags.ts在与polyfills.ts.

在zone-flags.ts文件中添加以下行：

(window as any).__Zone_enable_cross_context_check = true;

希望之后一切正常！如果你点击了上面的链接，

执行：ng serve --configuration es5以开发模式在 IE 中运行您的项目。

更新

看起来 angular 实际上有这方面的文档： angular.io/guide/deployment#fallback

查找“旧浏览器中的本地开发”，然后“为 ES5 配置服务”

该问题是由 Angular 8 的差异加载过程引起的。
