I have the same issue, is there an answer?

[emmanuelgautier]

I have the same issue.

[lilling]

I found that my problem was somthinf

[lilling]

II found my problem to be that my system.config.js wasn't like the ng team suggested file.
I found it by removing the catch statment on the system.config.js/ index.html bubbled to the console the exact problem

[emmanuelgautier]

@lilling Could you paste an example of your fix please ?

[emmanuelgautier]

Problem being fixed with a new system-config.js like that.

thanks to all, but also i have problems with @ngrx/store and @ngrx/core.

I added these lines but does not work

'@ngrx/core': 'vendor/@ngrx/core/bundles/core.min.umd.js',
  '@ngrx/store': 'vendor/@ngrx/store/bundles/store.min.umd.js',
  '@ngrx/effects': 'vendor/@ngrx/effects',

We've since moved to a webpack based build system and no longer support the SystemJS based one. You can find upgrading instructions here: https://github.com/angular/angular-cli#webpack-update
