Hi, this is most likely due to using asdf as your Crystal manager. I'd recommend just installing crystal directly https://crystal-lang.org/install/ for your OS.

Also, in case you're not aware, Crystal officially has a built-in REPL/Interpreter. You can build Crystal from source and compile with interpreter support, then just use crystal i to enter the REPL.

Thanks!

Indeed, the error was avoided by directly installed Crystal. And, I can use crystal -i.
