You are on an older version of Rustler (0.22.2) where the mix rustler.new task appears incompatible with Elixir 1.13. See the changelog, specifically a fix in 0.23.0
Assuming you’re on Elixir 1.13, if you upgrade Rustler in your mix.exs {:rustler, "~> 0.25.0"} and run mix deps.update --all, then it should work

Hi @JILL24 - welcome to the Elixir forum!
We (the moderators) combined your posts into a single new thread as duplicate posting is against the forum rules.
In addition, consider opening a new thread when asking a mostly-unrelated question. The “mark as answered” feature doesn’t work if you add a new question to a months-old answered one.
