It seems that the package assets are handled differently in the upcoming meteor 1.2 release.
While building the application:
.../app/client/stylesheets/main.sass:20:9:
Scss compiler error: file to import not found or unreadable:
.meteor/local/build/programs/server/assets/packages/meteoric_ionic-sass/ionic
Current dir:
.../app/client/stylesheets/
I get this error no matter how often I restart.
It seems that meteor does not copy the package anymore to the assets folder here:
.meteor/local/build/programs/server/assets/packages/meteoric_ionic-sass
The meteor upgrade notes mention a new way to specify assets for packages. See here:
