Namespaces in the same project fail to resolve.

[mitch-kyle]

I'm experiencing a failure to require sibling namespaces.

This happens with basilisp run as well as with cider even when the namespace is manually loaded into the repl.

I'm on a linux system and have basilisp installed with pip and bootstrapped in a venv with no other packages. I've also done the same experiment with the source files in the src directory with the same result. Removing the :require statement causes the file to run without error.

If you need anymore information please let me know.

Files:

• ./a.lpy

(ns a (:require [b]))

• ./b.lpy

(ns b)

Result:

$ basilisp version
Basilisp 0.1.0b2

$ python3 --version
Python 3.12.4

$ basilisp run a.lpy
