遇到的异常情况：在Jenkins中运行puppeteer脚本时，Could not find Chromium(rev. 1095492)(系统为Debian)

我使用 puppeteer 和 lighthouse 开发了一个基于 nodeJS 的项目。我正在使用puppeteer登录到任何需要用户登录的网站。登录后，我导航到任何页面，如我的订单、账户信息、订购页面等。

注意--我在Jenkins上把这个项目作为一个自由风格的项目。

细节中的确切错误- 遇到的异常：Exception encountered: Could not find Chromium (rev. 1095492)。这可能发生在以下两种情况

1. 你在运行脚本之前没有进行安装（例如npm install），或
2. 你的缓存路径配置不正确(是：/root/.cache/puppeteer)。

在调用我的脚本之前，尝试了以下3个脚本的运行--->；

1. apt-get update

2. apt-get install -y gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget libgbm-dev

3. npm install -g

npm run MyScriptName

Package.json--> "devDependencies": { "chromedriver": "^108.0.0", "date-and-time": "^2.4.1", "lighthouse": "^9.6.8", "log4js": "^6.7.1", "puppeteer": "^19.7.1" },

我能够用下面的代码来解决这个问题：

const browserFetcher = puppeteer.createBrowserFetcher();
      let revisionInfo = await browserFetcher.download('1095492');

      const browser =await puppeteer.launch({
          executablePath: revisionInfo.executablePath,
          ignoreDefaultArgs: ['--disable-extensions'],
          headless: true,
          args: ['--no-sandbox', "--disabled-setupid-sandbox"]
        });

现在chrome被放置在用户目录"~/.cache/puppeteer"中。检查该目录的权限，以及它是否属于你正在运行应用程序的用户。

或者通过PUPPETEER_CACHE_DIR环境变量或puppeteer.config.cjs配置文件来设置Chromium的下载文件夹。

index.js

const puppeteer = require('puppeteer')

/**
 * Responds to any HTTP request.
 *
 * @param {!express:Request} req HTTP request context.
 * @param {!express:Response} res HTTP response context.
 */
exports.helloWorld = async (req, res) => {
  await puppeteer.createBrowserFetcher().download(puppeteer.PUPPETEER_REVISIONS.chromium)
  const browser = await puppeteer.launch()
  const page = await browser.newPage()
  await page.goto('https://example.com/')
  res.send(await page.content())
  await browser.close()
}

package.json

{
  "name": "sample-http",
  "version": "0.0.1",
  "dependencies": {
    "puppeteer": "^19.7.5"
  }
}

它与Google Cloud Functions Node.js 16一起工作。
