一个祖传老代码打包，提示如下错误：

ReferenceError: webpackJsonp is not defined at http://localhost:8100/build/main.js:1:1

一搜发现应该是使用了新版本的Ionic-App-Scripts导致的：

This is a breaking change in Ionic-App-Scripts https://github.com/ionic-team/ionic-app-scripts/releases/tag/v2.0.0 src/index.html must be modified to include a new vendor script tag .

中文意思是：这版本有一个断式变更，src/index.html文件需要一个包含vendor script的标签，即需要添加这一段：

  <script src="build/vendor.js"></script>

而且必须要放在<script src="build/main.js"></script>前面，完成后如下：

...
<body>

  <!-- Ionic's root component and where the app will load -->
  <ion-app></ion-app>

  <script src="cordova.js"></script>

  <!-- The polyfills js is generated during the build process -->
  <script src="build/polyfills.js"></script>

  <!-- all code from node_modules directory is here -->
  <script src="build/vendor.js"></script>

  <!-- The bundle js is generated during the build process -->
  <script src="build/main.js"></script>

</body>
