问题描述
我正在开发一个具有两个Angular 4应用程序的项目，并且在配置Webpack(3.5.2)时遇到一些问题.我在仅一个应用程序中收到此错误:
I'm developing a project that has two Angular 4 application and I'm having some problem configuring Webpack (3.5.2). Im getting this error in just one of the applications:
Uncaught ReferenceError: webpackJsonp is not defined
at styles.bundle.js:1
(anonymous) @ styles.bundle.js:1
vendor.bundle.js:1
Uncaught ReferenceError: webpackJsonp is not defined
at vendor.bundle.js:1
(anonymous) @ vendor.bundle.js:1

Uncaught ReferenceError: webpackJsonp is not defined

我的Webpack的配置分为两个文件:

推荐答案
我和朋友聊天，他说我的问题是index.html中导入文件的顺序，应该是:
I talked to a friend and he said me the problem was the order of the import files in index.html, it should be:
<script type="text/javascript" src="/manifest.bundle.js"></script>
<script type="text/javascript" src="/polyfills.bundle.js"></script>
<script type="text/javascript" src="/app/app/vendor.bundle.js"></script>
<script type="text/javascript" src="/app/app/styles.bundle.js"></script>
<script type="text/javascript" src="/app/app/main.bundle.js"></script>
但是是:
<script type="text/javascript" src="/app/app/styles.bundle.js"></script>
<script type="text/javascript" src="/app/app/vendor.bundle.js"></script>
<script type="text/javascript" src="/app/app/main.bundle.js"></script>
<script type="text/javascript" src="/manifest.bundle.js"></script>
<script type="text/javascript" src="/polyfills.bundle.js"></script>
因此，我可以使用两种方法之一，对两个项目仅使用一个供应商，或将HtmlWebpackPlugin配置为手动订购文件.因为我可以在两个应用程序中使用一个供应商，所以我决定只使用一个供应商:
So I could use one of two approachs, use only one vendor for the two projects or configure the HtmlWebpackPlugin to manually order the files. As I could use one vendor for the two applications, I decided use only one vendor:
