Vendoring error

[ghost]

how to correctly vendor this?

$ cat ast.js        
import { parse } from "https://deno.land/x/swc@0.2.1/mod.ts";

const code = "const a = 44;";

const ast = parse(code, {
  syntax: "ecmascript",
  comments: false,
});

console.log(ast);

$ deno vendor ast.js
Vendored 5 modules into vendor/ directory.

To use vendored modules, specify the `--import-map vendor/import_map.json` flag when invoking Deno subcommands or add an `"importMap": "<path_to_vendored_import_map>"` entry to a deno.json file.

$ deno run --import-map=vendor/import_map.json ast.js
