Angular 2 AoT编译器：没有错误，但是肯定有问题

Question

I've been banging my head at this for 3 days, trying to get Ahead-of-Time compilation of my Angular 2 rc.6 application to work.

The application compiles and runs just fine using Just-in-Time compilation.

I have installed all dependencies, run ngc (the compiler), changed my main.ts to use platformBrowser() , and run ngc again.

There is no error in the console. The .ngfactory.ts files are generated. The .js files also. So far so good. Here is my structure (it's a mess but I'll address that if I can ever get this working)

The app runs out of dist/ . Problem is, once I update systemjs.config.js and change map['app'] from dist to dist/dev and run the App, things go downhill fast.

The first indication that something is really wrong is that whereas I expected the number of HTTP requests and the amount of data to be drastically reduced with AoT, the opposite happened. I now have 200 more requests at bootstrap!

Secondly, even though there were no errors during compilation, the app will not run. I get a 404 not found at the path: http://localhost/traceur . What? Why is traceur involved? isn't that used for in-browser transpilation? Where can I start looking for what's wrong?

Answer 1

Same,I followed the official guides with systemjs as my loader and using the UMD bundles. But that would not map correctly! So I re-configured my systemjs settings and am managing to get all the packages. But now traceur.js is the only missing package. What is that about ?!

Edit: So I mapped tracuer in systemjs, ,like so:

'traceur': 'node_modules/traceur/src/traceur'

But... now nothing shows up on my page. I believe my whole configuration with the packages is wrong to begin with though because why was my app requesting packages that weren't mapping correctly with the UMD bundles?
