由于某些原因，Visual Studio Code无法识别CLI“Deno.args”等，如下面的代码所示。我已经检查了settings.json，deno已启用。

import { readStringDelim } from "https://deno.land/std/io/buffer.ts";
async function tail(fileName: string) {
  const fileReader = await Deno.open(fileName);
  await Deno.seek(fileReader.rid, 0, Deno.SeekMode.End);
  const watcher = Deno.watchFs(fileName);
  for await (const event of watcher) {
    if (event.kind !== "modify") continue;
    for await (const line of readStringDelim(fileReader, "\n")) {
      if (!line) break;
      yield (line.trim());
    }
  }
}
const file = Deno.args[0];
if (!file) {
  console.error("File must be provided");
  Deno.exit(1);
}
for await (const line of tail(file)) {
  console.log("Got line:", line);
}
