node.js - 语法错误: Cannot use import statement outside a module using puppeteer

Question

您好，我一直尝试运行 puppeteer 测试，但不断遇到此问题。请帮忙谢谢。 enter image description here 代码:

import puppeteer from 'puppeteer';

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  await page.goto('https://developers.google.com/web/');

  // Type into search box.
  await page.type('.devsite-search-field', 'Headless Chrome');

  // Wait for suggest overlay to appear and click "show all results".
  const allResultsSelector = '.devsite-suggest-all-results';
  await page.waitForSelector(allResultsSelector);
  await page.click(allResultsSelector);

  // Wait for the results page to load and display the results.
  const resultsSelector = '.gsc-results .gs-title';
  await page.waitForSelector(resultsSelector);

  // Extract the results from the page.
  const links = await page.evaluate(resultsSelector => {
    return [...document.querySelectorAll(resultsSelector)].map(anchor => {
      const title = anchor.textContent.split('|')[0].trim();
      return `${title} - ${anchor.href}`;
    });
  }, resultsSelector);

  // Print all the files.
  console.log(links.join('\n'));

  await browser.close();
})();

错误:

我尝试重新安装 Node js 和 npm，但没有任何效果。

{
 "name": "my-app",
 "version": "0.0.0",
 "type": "module",
 "scripts": { ...
 },
   ...
 }

在 package.json 文件中添加 type:module 或安装最新的 Nodejs
