title: Deno -> How do I run the codes to run without errors?
body: <p>I'd like to import from local</p>
  <p>Testing environment Deno v1.6.0</p>
  <p>I've tried local import by Deno lang</p>
  <p>Local directory</p>

  <p>'./localExport/arithmetic.ts' File to be imported</p>
  <pre><code>function add(outbound: number, inbound: number): number {

  <pre><code>import { add, multiply } from &quot;./localImport/arithmetic.ts&quot;;

  console.log(totalCost(19, 31, 1.2));
  console.log(totalCost(45, 27, 1.15));

  <p>Run the above codes</p>
  <pre><code>❯ deno run src/sample/localImportExport.ts

  <p>I got the errors:</p>
