在Vultr,Digital Ocean,Heroku或GAE上运行google chrome puppeteer

Question

我试图在Heroku,GAE flex,Digital Ocean和Vultr上运行Google Chrome木偶操作员,但是在我使用puppeteer的路线上,实例只是挂起,直到它出现502错误.我正在使用这个简单的代码:

var express = require('express');
var router = express.Router();
const puppeteer = require('puppeteer');

router.get('/', function(req, res, next) {
    (async() => {
        const browser = await puppeteer.launch();
        const page = await browser.newPage();
        await page.goto('http://example.com');
        await page.screenshot({path: 'example.png'});

        browser.close();
        res.send('screen grabbed');
    })();
});

module.exports = router;

我知道puppeteer现在使用节点6,但我设置package.json如下:

{
  "name": "puppeteer",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www",
    "deploy": "gcloud app deploy --version dev"
  },
  "engines": {
    "node": "8.4.0"
  },
  "dependencies": {
    "body-parser": "~1.17.1",
    "cookie-parser": "~1.4.3",
    "debug": "~2.6.3",
    "express": "~4.15.2",
    "morgan": "~1.8.1",
    "pug": "~2.0.0-beta11",
    "puppeteer": "^0.10.2",
    "serve-favicon": "~2.4.2"
  }
}

在Vultr Ubuntu 16.04 x64中,我收到以下错误:

错误:无法启动chrome!

/root/mysite/node_modules/puppeteer/.local-chromium/linux-497674/chrome-linux/chrome:加载共享库时出错:libpangocairo-1.0.so.0:无法打开共享对象文件:没有这样的文件或目录

我解决了以下问题,确保安装了以下puppeteer依赖项:

安装了所有依赖项

sudo apt-get install 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

然后将args传递给puppeteer启动命令,如下所示:

(async() => {

const browser = await puppeteer.launch({args: ['--no-sandbox', '--disable-setuid-sandbox']});
const page = await browser.newPage();
await page.goto('http://example.com');
await page.screenshot({path: 'example.png'});
res.send('screen grabbed');
browser.close();
})();
