这是怎么回事?为什么找不到SystemJS ...
What is going on ? Why is it not finding SystemJS ...
注意:我的文件夹结构是该应用程序位于资产/管理文件夹下，如下所示:
NOTE: My folder structure is that the app is located under assets/management folder like so:
management/
├── app/
| ├──root/
│ ├── root.component.ts
| ├── root.module.ts
├──main.ts
注意2:删除System.import ...导致未引发错误
NOTE2: removing System.import ... results in the error not being thrown
System.import('app')
.then(null, console.error.bind(console));
推荐答案
我敢打赌，您需要先加载 system.src.js ，然后再加载 system-polyfills.js .您现在正以另一种方式这样做.
I bet you need to first load system.src.js and then system-polyfills.js. You're doing it the other way around now.
<script src="/js/node_modules/systemjs/dist/system.src.js"></script>
<script src="/js/node_modules/systemjs/dist/system-polyfills.js"></script>
