我正在尝试在predix-web-starter应用程序中使用Google Chrome Puppeteer。当我在Windows上本地运行代码时，它可以完美运行。将其推送到Predix后，当我运行包含Puppeteer代码的部件时，将导致错误。似乎有一些缺少的库问题（不确定是什么）。
简而言之，如何让Puppeteer在Predix上运行？
Predix-web-starter：https://github.com/PredixDev/predix-webapp-starter
木偶：https://www.npmjs.com/package/puppeteer
木偶代码：
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://news.ycombinator.com', {waitUntil: 'networkidle'});
await page.pdf({path: 'hn.pdf', format: 'A4'});
await browser.close();
})();

最佳答案
最近发现，使用cloudfoundry/apt-buildpack和cloudfoundry/nodejs-buildpack，可以通过将共享库包含在apt.yml中来安装它们。但是predix不允许multibuildpacks push，因此出于未知原因，我尝试使用cloudfoundry/multi-buildpack而不成功。我解决问题的方法是创建一个自定义buildpack，从apt接收代码，将其放在nodejs buildpack上，然后在manifest.yml上包括git repository url。
这是我的custom buildpack。
