Angular 2 RC.5 Plunker error: TypeError: core_1.NgModule is not a function

问题

I upgraded my Angular 2 Plunker from RC.4 to RC.5 by doing the following:

• updated systemjs.config.js to match the quickstart plunker
• updated main.ts to match the quickstart plunker
• created file app/app.module.ts, and populated it with what the quickstart plunker has

I don't see any other changes that are required for my simply plunker.

I keep getting this error: Error: TypeError: core_1.NgModule is not a function(…)

I hit the exact same problem on my project. It worked on 1 pc, didn't work on another. Turns out the solution was simple:

Clear your browser cache

Although I'm not sure what the problem is, this fixes it:

• save your changes
• reload the page/plunker

The error no longer appears. (I assume it has something to do with some old files that are not getting regenerated properly.)

The tour of heroes tutorial has changed and introduced app.module.ts and also versions in systemjs.config.js for ex: ngVer is now @2.0.0-rc.5'. Replace the systemjs.config.js and everything worked fine for me.

You can follow the angular upgrade rc4 to rc5 docs here: https://angular.io/docs/ts/latest/cookbook/rc4-to-rc5.html
