What version of Crystal are you using?

[lost22git]

Crystal 1.9.2 [1908c816f] (2023-07-19)

LLVM: 15.0.7
Default target: x86_64-unknown-linux-gnu

If this is happening on an existing Athena project, i.e. that has a shard.lock, try doing a shards update. Otherwise if it's a brand new project, I am unable to reproduce this :thinking:.

Oh, make sure you have PCRE2 installed. Athena no longer supports PCRE1.

It seems libyaml-dev is also required, but the docs don't seem to mention

How did you install Crystal? Normally these should be installed as dependencies automatically via your package manager.
