Encountered error when formatting types with Prettier t [Error]: Couldn't resolve parser "typescript"

[iccicci]

I tried again to update to peggy v4.2.1 but now (more than #119 ) I get this warning (several times).

Encountered error when formatting types with Prettier t [Error]: Couldn't resolve parser "typescript". Parsers must be explicitly added to the standalone bundle.

Any idea? 😞

Thank you
