我正在为Wordpress 4.8编写一个Angular 4主题,主要用于Edge和Chrome浏览器。我的测试脚本在测试中失败。出现错误的ts:

Uncaught SyntaxError: Unexpected token import at src/test.js:1

我的tsconfig。src文件夹中的json如下所示:

{
  "compilerOptions": {
  "module": "commonjs",
  "target": "es5",
  "moduleResolution": "node",
  "sourceMap": true,
  "emitDecoratorMetadata": true,
  "experimentalDecorators": true,
  "lib": [ "es2016", "es5", "dom"],
  "noImplicitAny": true,
  "suppressImplicitAnyIndexErrors": true
}
}

t配置。根级别的json是:

{
  "compileOnSave": false,
  "compilerOptions": {
  "outDir": "./dist/out-tsc",
  "baseUrl": "src",
  "sourceMap": true,
  "declaration": false,
  "moduleResolution": "node",
  "emitDecoratorMetadata": true,
  "experimentalDecorators": true,
  "target": "es5",
  "typeRoots": [
     "node_modules/@types"
     ],
  "lib": [
     "es2016",
     "dom",
     "es5"
     ]
  }
 }

我的测试。输电系统包括:

import {BrowserDynamicTestingModule, platformBrowserDynamicTesting} from 
"@angular/platform-browser-dynamic/testing";
import {getTestBed} from "@angular/core/testing";

declare var _karma_: any;
declare var require: any;

_karma_.loaded = function () {};

getTestBed().initTestEnvironment(
    BrowserDynamicTestingModule,
    platformBrowserDynamicTesting()
);

const context = require.context('./', true, /\.spec\.ts$/);

context.keys().map(context);

_karma_.start();

解决此错误的最佳方法是什么?
