How to solve it please?

You should use the scripts in the package.json of the root folder. Don’t ‘cd’ into the extensions directory. You can just ‘pnpm run watch:vue-language-features’ in the root folder.

Tip: If you are using vscode you can just start the debug mode with ‘Launch Vue Language Features’

You need use pnpm
