Repro steps.

Just switched to version 1.5 with Angular 5 while trying to rebuild the app, trying to run ng build --prod. The build itself works fine, no error occurs in the cli, just the produced output is not working in the browser anymore. Here’s the build output (with build-optimizer enabled)

$ ng build --prod
Time: 122549ms

chunk {3} inline.022aa018a8a39e60af21.bundle.js (inline) 1.45 kB [entry] [rendered]

I also tried removing the build-optimizer ng build --prod --build-optimizer false, still the same problem in the browser. If I don’t build it with the --prod flag, everything is working fine. So I guess this has something to do with the --prod flag.

The log given by the failure.

Here’s what the browser tells me directly on loading the page.

Uncaught TypeError: o.JitCompilerFactory is not a constructor

Desired functionality.

Production build app working in the browser again.
