Missing JsModule("string-argv") when using npm("string-argv", "0.3.1", generateExternals = true)

[vlsi]

Just in case, here's how the package looks like in node_modules:

export { parseArgsStringToArgv as default, parseArgsStringToArgv };
declare function parseArgsStringToArgv(value: string, env?: string, file?: string): string[];

package.json:

{
  "name": "string-argv",
  "description": "string-argv parses a string into an argument array to mimic process.argv. This is useful when testing Command Line Utilities that you want to pass

Here's the error when JsModule is not present:

ReferenceError: parseArgsStringToArgv is not defined
