@jannomeister the new version of nativescript-them-core is a major version meaning that it comes with some breaking changes. It is also a beta in active development.

Still, to use the 2.0.2 version refer to this updated README . Notice that the imports for scss files have changed as follows:

/* or alternatively SCSS: */

    @import "~nativescript-theme-core/core";
    @import "~nativescript-theme-core/blue";

[jannomeister]

@NickIliev thanks for the quick response. For now I reverted back to the old version. :)

I made the suggested changes, had already made and the error is still happening.

I'm hitting the same error as @carlosdelfino on a project I migrated to {N} 6.0.

I reverted to version 1.0.6 and everything is working. This plug-in REALLY needs better information about breaking changes, and exactly what changes are needed, with examples, for existing code. For example, the readme says some javascript is required. Anywhere in particular? I'm guessing app.js, but is it the same for all project types?

And if you want to use the compat versions, what exactly is needed?

[carlosdelfino]

In order not to give up on using the project I took a drastic action and made the following insertion:
At least I always remember to check if the new versions are compatible.

@import "nativescript-theme-core/scss/core/_index";
