node.js - nodejs 为什么我不能使用 puppeteer-core？

Question

我正在尝试使用puppeteer-core，chrome-aws-lambda因此可以将函数上传到 aws lambda，但是在本地运行脚本时出现错误，我尝试卸载并重新安装模块但仍然出现错误，这是我的代码

const chrome = require('chrome-aws-lambda');
const puppeteer = require('puppeteer-core');
(async () => {
    const browser = await puppeteer.launch({
        args: chrome.args,
        executablePath: "/home/usern/Desktop/serverless/node_modules/chrome-aws-lambda/bin/chromium-75.0.3765.0.br",
        headless: chrome.headless,
    });
    const page = await browser.newPage();
    await page.goto('https://example.com');
  await browser.close();
})();

它给了我这个错误，我不知道该怎么做才能解决它

puppeteer-core不包括chrome与软件包不同的安装puppeteer。

如果您希望puppeteer在 Lambda 中使用，请尝试使用已经chrome为您提供的 Lambda 层，例如https://github.com/RafalWilinski/serverless-puppeteer-layers。
