import styles from the library into the library

[Dmitriy-Krivetsky]

Hello!
We create a project with its own npm packages one of which is core (common package).
I want to import bootstrap styles (from node_modules) into the core, but I'm having problems with imports in the base application

To reproduce:

core-package:

// main.less
@import "bootstrap/dist/css/bootstrap.min.css";
// I have also tried this recording option
@import "~bootstrap/dist/css/bootstrap.min.css";

application-base:

// main.less
@import "core-package/dist/styles/main";
// I have also tried this recording option
@import "~core-package/dist/styles/main";

Structure for greater understanding:

src
- node_modules
-- bootstrap
-- core-package
--- main.less (core)
- styles
-- main.less (app)

Current behavior:

When I start application-base

 application-base@0.0.1 start
> concurrently --kill-others "less-watch-compiler --config less-watcher.config.json" "react-scripts start"

Expected behavior:

I want to enable importing bootstrap styles into a core less file and just import the core less file to connect all the styles

Environment information:

• less version: ^4.1.3
• less-watch-compiler version: ^1.16.3
• nodejs version: 17.3.0
• react version: 18.0.2
• operating system: MacOS

Thanks for the prompt reply
I previously tried some solutions from these sources, adjusting webpack.config.js also failed

The weird thing is that npm start works sometimes, maybe 3/10 starts

But the error changed to:

> application-base@0.0.1 start
> concurrently --kill-others "less-watch-compiler --config less-watcher.config.json" "PORT=4000 react-scripts start"

This looks like an issue with less-watch-compiler which seems to be independently trying to resolve imports?
