【发布时间】：2019-03-07 15:50:15
【问题描述】：

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

第 88 行

class AnimationBuilder {
}

SCRIPT1002：语法错误

文件：main.js，行：91422，列：35

第91422行同上

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

我确实有一个肥皂连接，它无论如何都不能在本地主机上工作。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>

tsconfig.json

{
  "compileOnSave": false,

  "compilerOptions": 
  {
    "forceConsistentCasingInFileNames":true,
    "outDir": "./dist/out-tsc",
    "sourceMap": true,

    ]
  },

  "files": [
    "src/app/app.module.ts"
  ],

  "include": [
    "src/**/*"
  ]
}

我还有一个 tsconfig.app.json 和 tsconfig.spec.json

polyfills.js

/**

 * You can add your own extra polyfills to this file.
 *
 * This file is divided into 2 sections:

 *   2. Application imports. Files imported after ZoneJS that should be loaded before your main
 *      file.
 *
 * The current setup is for so-called "evergreen" browsers; the last versions of browsers that
 * automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera),
 * Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.

【问题讨论】：

每行抛出错误的代码是什么？
@sgunliffe 已更新
更新到最新的 cli 创建一个新的 cli 项目进入 polyfills.ts 并取消注释行：22 - 35。运行 ng serve 并检查是否有效

标签： angular internet-explorer

【解决方案1】：

对于遇到类似问题的其他人：

Angular 8 已将默认目标设为 es2015 而不是 es5

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

您还需要取消注释 polyfills.ts 中的 polyfill，具体取决于您使用的内容。

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'; 然后在与polyfills.ts 相同的目录中创建zone-flags.ts 文件。

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！如果你按照上面的链接，

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”，然后查找“为 ES5 配置服务”

问题是由 Angular 8 的不同加载过程引起的。

【解决方案2】：

看起来您正在使用或传递您的 JavaScript，但还远远不够，并且您遇到语法问题，因为您尝试使用 IE11 不支持的功能。

例如

JS 类 - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes
JS 构造函数 -（类的一部分，见上文）

【讨论】：

【解决方案3】：

要完成@Lionheart Scholar 所说的，还有最后一步：在 tsconfig.app.json "files" 部分注册 zone-flags.ts 文件，如下所示：

{
  "extends": "./tsconfig.json",
  "compilerOptions": {
    "outDir": "./out-tsc/app",
    "types": []
  },
  "files": [
    "src/main.ts",
    "src/polyfills.ts",
    "src/zone-flags.ts"
  ],
  "include": [
    "src/**/*.d.ts"
  ]
}

【讨论】：

【解决方案4】：

在 tsconfig.json 替换“目标”：“es5”， //"目标": "es2015",

【讨论】：

如果你忘记了。您的构建将使用 es5。
