我的应用路由为

const routes: Routes = [
    {
        path: '',
        loadChildren:  'app/content/pages/pages.module#PagesModule'

    },
    {
        path: 'layout',
        loadChildren: 'app/content/layout/layout.module#LayoutModule',      
    },
    {
        path: '**',
        redirectTo: ''
    }
];

推荐答案

经过几个小时的投资，终于找到了我的解决方案 关于promise((t，n)=>，

After investing some hours finally found my solutions Issue about promise((t,n) => ,

1. 首先，打开src/polyfills.ts文件，然后取消注释

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
// import 'core-js/es6/symbol';
// import 'core-js/es6/object';
// import 'core-js/es6/function';
// import 'core-js/es6/parse-int';
// import 'core-js/es6/parse-float';
// import 'core-js/es6/number';
// import 'core-js/es6/math';
// import 'core-js/es6/string';
// import 'core-js/es6/date';
// import 'core-js/es6/array';
// import 'core-js/es6/regexp';
// import 'core-js/es6/map';
// import 'core-js/es6/weak-map';
// import 'core-js/es6/set';

=> IE中不支持lambda表达式，因此我们可以用代码function()代替此表达式.

=> lambda expression does not support in IE so we can replace with code function() instead of this expression.

1. 安装一些软件包

1. Install some packages

npm install-保存web-animations-js

npm install --save web-animations-js

npm install-保存classlist.js

npm install --save classlist.js

然后我从一个npm软件包(fuctbase64/index.js)中发现了Promise问题

Then i was found promise issue from one of the npm package (fuctbase64/index.js)

module.exports = function (event) {
  return new Promise((resolve, reject) => {
    let reader = new FileReader();
    let files = event.target.files;
    let len = files.length;
    if (len > 1) {
      reject(new DOMException("Only one file can be uploaded at a time"));
    } else {
      reader.onerror = () => {
        reader.abort();
        reject(new DOMException("Problem parsing input file."));
      };
      let file = files[0]
      reader.onload = (evt) => {
        const uint = new Uint8Array(evt.target.result);
        let bytes = [];
        uint.map(byte => {
          bytes.push(byte.toString(16));
        });
        const hex = bytes.join('').toUpperCase();
        let base64 = reader.result.split(',')[1];
        file.base64 = base64;
        file.binaryFileType = getMimetype(hex);
        resolve(file);
      };
      reader.readAsDataURL(file);
    }
  });
}

用

module.exports = function (event) {
  return new Promise(function(resolve, reject)  {
    let reader = new FileReader();
    let files = event.target.files;
    let len = files.length;
    if (len > 1) {
      reject(new DOMException("Only one file can be uploaded at a time"));
    } else {
      reader.onerror = function() {
        reader.abort();
        reject(new DOMException("Problem parsing input file."));
      };
      let file = files[0]
      reader.onload = function(evt){
        const uint = new Uint8Array(evt.target.result);
        let bytes = [];
        uint.map(function(byte) {
          bytes.push(byte.toString(16));
        });
        const hex = bytes.join('').toUpperCase();
        let base64 = reader.result.split(',')[1];
        file.base64 = base64;
        file.binaryFileType = getMimetype(hex);
        resolve(file);
      };
      reader.readAsDataURL(file);
    }
  });
}
