no @shexjs module

Env Windows 10, node -v : 12.18.1

Hi, wanting to add sdk-forms as dependency of a project, & running
`npm install --save @inrupt/solid-sdk-forms`

I got

  ERROR in ./node_modules/@inrupt/solid-sdk-forms/dist/solid-forms.es5.js
    Module not found: Error: Can't resolve '@shexjs/core' in 'C:\Users\Smag\Documents\dev\shighl-elements\node_modules\@inrupt\solid-sdk-forms\dist'

     @ ./src/shighl-crud.js

    ERROR in ./node_modules/@inrupt/solid-sdk-forms/dist/solid-forms.es5.js
    Module not found: Error: Can't resolve '@shexjs/parser' in 'C:\Users\Smag\Documents\dev\shighl-elements\node_modules\@inrupt\solid-sdk-forms\dist'

     @ ./src/shighl-crud.js

And no @shexjs folder in /node_modules, perharps @shexjs must migrate from dev-dep to dep in package.json or run a "npm build " at the end of install?

I tried to install @shexjs/core & @shexjs/parser manually as dep of my project, but now, when i run 'npm run dev' with a webpack conf, i got

   ERROR in ./node_modules/@shexjs/parser/lib/ShExJison.js
