E0050: Unknown Path Export

A path import (import { name } from "./other.star";) referenced a name that the target module does not declare at the top level.

Example (error)

// helpers/math.star
fn add(a: i64, b: i64) -> i64 { a + b }

// entry.star
import { multiply } from "./helpers/math.star"; // Error: helpers/math.star does not export `multiply`

Fix

Either define the missing item in the target module, or import an item that the module actually declares:

import { add } from "./helpers/math.star";

Only top-level definitions (fn, struct, enum, abi, utxo) are exportable. Local bindings inside function bodies are not visible to other modules.
