我收到这个错误。我已经设置了以下内容: puppeteer.launch({ args: ['--no-sandbox'] });

已添加:https://github.com/jontewks/puppeteer-heroku-buildpack 构建包。

任何人都可以帮我解决这个问题吗？代码在本地主机上运行良好。但是当我将它部署到heroku上时，它不断地给出这个错误。

Answer 1

我在使用 puppeteer 和 Heroku 时遇到了同样的问题。我安装了您提到的相同构建包，并使用了以下代码，现在它工作正常。

puppeteer.launch({headless: true, args: ['--no-sandbox', '--disable-setuid-sandbox']})

P.S:我在安装构建包后再次部署。
