Error message is unclear when wrongly importing module

[Nautigsam]

I have the two following modules:

// external.ts
export default external = "external";

// fail.ts
import external from "external.ts";
console.log(external);

Then:

$ deno run fail.ts
Compiling file:///home/user/fail.ts
relative URL with a cannot-be-a-base base

This error message is very unclear. It should at least mention the file and the line number of the import.

Hello! I would like to work on this if possible, with some guidance. Where should I look?

I just installed Deno, and run straight into this issue. This should be higher priority... no idea where to begin fixing this in my codebase.

This issue will be fixed in #2572
