Webpack構建成功，我可以瀏覽到我的網頁。但是，Javascript失敗，說：'進口聲明可能只出現在模塊的頂層'在webpack中，如何解決'導入聲明可能只出現在模塊的頂層？'
下面是我輸出的包含import語句的app.js。
如何更改我的webpack配置文件以在構建時擺脫導入語句？
webpackJsonp([0],{
/***/ 0:
/***/ function(module, exports, __webpack_require__) {
__webpack_require__(1);
__webpack_require__(74);
module.exports = __webpack_require__(76);
/***/ },
/***/ 76:
/***/ function(module, exports) {
"use strict";
import 'app/tools/typescriptImports.ts';
import * as mainScreenHelper from 'app/tools/mainScreenHelper';
import React from 'react';
import * as reactDom from 'react-dom';
import Router from 'react-router';
import createBrowserHistory from 'history/lib/createBrowserHistory';
import routes from 'app/tools/routes';
import 'style/app.scss';
import 'font-awesome/scss/font-awesome.scss';
mainScreenHelper.removeLoadingScreen();
mainScreenHelper.createReactApp();
/***/ }
});
//# sourceMappingURL=app.js.map
這是我目前的配置文件：
'use strict';

你可以添加你的tsconfig.json？ –
