我在应用中使用 Angular 4.4.1 + SystemJS 0.20.19 + NgBootstrap 1.0.0-beta.5 。该应用按照此instructions并具有以下 SystemJS 配置
，在 Angular JIT 模式下工作 meta: {
"./*": {
"esModule": true
}
}
我使用了＆＃34; node_modules / .bin / ngc＆＃34; -p tsconfig-aot.json 将应用程序编译为 AOT 应用程序。
在 AOT 应用中，我有 SystemJS map配置，如本问题末尾所示。
在JIT模式下工作的相同应用程序无法在AOT模式下运行，并生成以下错误：

问题：
我无法知道哪个模块导致此错误。经过多次调试后，错误在加载NgBootstrao NgbModel时出现。如何解决此错误？
我是否可以使用一些配置设置来查看 SystemJS 在浏览器控制台中加载的模块的进度/日志？
