** (RuntimeError) calling `cargo metadata` failed. #618

Closed Maxino22 closed 1 month ago

Maxino22 commented 1 month ago

I'm pretty new to this I have experience with elixir but very basic on rust. reading articles on rustler seems pretty cool what you can do with the two but I haven’t been able to get past the setup and running the demo... i keep getting the metadata failed I tried downgrading but no difference.

This is what is on terminal.
