Refactor the error message with the adding the information from the imported
module, for example:
// a.mjs
import { a } from "./b.mjs";
// b.mjs
const b = 1;
Originally the error message is "import not found: default", now it
becomes "The requested module: b.mjs doesn't provide an export named: a"
// c.mjs
import { c } from "./d.mjs";
// d.mjs
export * from "./d1.mjs";
export * from "./d2.mjs";
// d1.mjs
export const c = 1;
// d2.mjs
export const c = 2;
Originally the error message is "ambiguous import: c", now it becomes
"The requested module d.mjs contains ambiguous star export: c from
d1.mjs and d2.mjs"
Add another error message for circular import:
// e.mjs
export { e } from "f.mjs";
// f.mjs
export { e } from "e.mjs";
Originally it was "indirect export not found: e", now it is
"The request module: f.mjs contains circular import: e".
