Recreation

Crete a new app using the master vue-cli-template.

Create app.ios.scss and app.android.scss in the root. Then create scss/_index.scss with any theme and the core-theme index. Run with tns run <android|ios> --bundle, and the following error occurs:

Error: Css styling failed: Error: undefined:1:16: missing '{'

App runs, but styling is not correct.

There are no other errors anywhere. Closest thing to anything CSS related is the succesful build through mini-css-extract-plugin:

Child mini-css-extract-plugin ../node_modules/css-loader/index.js??ref--3-3!../node_modules/sass-loader/lib/loader.js!app.scss:
    Entrypoint mini-css-extract-plugin = *
    [../node_modules/css-loader/index.js?!../node_modules/sass-loader/lib/loader.js!./app.scss] ../node_modules/css-loader??ref--3-3!../node_modules/sass-loader/lib/loader.js!./app.scss 19.6 KiB {mini-css-extract-plugin} [built]

Further information

If I comment the theme reference from the top of _index.scss, the error goes away, but then of course it will complain that variables are missing. I examined the resulting app.scss file, and VS Code only complained about non-standard properties - nothing about braces anywhere.

In other issues and support threads, I've read about this being the result of empty SCSS files, though adding a rule doesn't appear to help (if it did, I'd have skipped opening this issue).

A full platform remove doesn't help either.

I'm not having any issues with infinite loops (given the resolution of #53 - Chokidar appears to be working in this case).

Is there any more information you'd like me to provide to trace this down? Could it actually be a problem with my JS?

Thanks in advance 😃
