=================================================================================

My env info: ember-cli: 3.15.2 node: 10.13.0 os: linux x64

It builds normally when I removed this addon.

Thanks

I had the same issue. The root cause of it was the recently released moment v2.25.1 package. Workaround was to pin moment to v2.24.0 (yarn resolution worked for me).

[aman-adriano]

thanks @sbflynn

Is momentjs is a dependency of ember-pikaday through ember-cli-moment-shim? I don't see it in pikaday's depencies. Glad to know I'm not the only one having this issue.

[jrjohnson]

This should be fixed with the release of ember-moment-shim v3.8.0 which no longer double minifies code from moment.
