Version: 1.5.0 Angular2 version 2.4.5 as well as 2.4.6 Angular cli version 1.0.0-beta.30 as well as 1.0.0-beta.26

During aot serve I get this error. Any ideas?

@metavurt Thanks! I published that change as 1.5.2 see https://github.com/tb/ng2-nouislider/commit/8f03307ec2b2ab64c8a86a7d0edfbd922a22d9d0

A radical workaround is to use replace the library by the file https://github.com/tb/ng2-nouislider/blob/master/src/nouislider.ts. Just copy it somewhere in your source folder and remove the library from the packages.json until the bug has been fixed.

I can confirm

Adding “@ngtools/webpack”: “1.2.3” to package.json resolved this issue for me.

I don’t think this issue should be closed though. We shouldn’t have to add this to our package.json. The dependencies for this package (ng2-nouislider) should be setup correctly to solve this issue.

Rock n roll, @tb, glad to be of help!

Can confirm. Am getting same error with simple ng build --prod. Error specifically points to ng2-nouislider’s ts.

I’m digging into it right now, and I will add my two cents’ worth that yes, when releasing, either things like this should be clarified in the instructions on a readme, or should be resolved within the package itself. I recognize that the landscape is still changing rapidly these days, but it is worth it to communicate upfront that a little housekeeping may be necessary to get a particular directive to work in any one person’s production environment.

I will post any updates if I find a working case that isn’t a hack.
