我收到此错误。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 到构建包。

有人可以帮我这个忙吗？代码在本地主机上运行良好。但是当我在heroku上部署它时，它会不断出现此错误。

我在操纵p和Heroku时遇到了同样的问题。我安装了您提到的同一构建包，并使用了以下代码，现在可以正常使用了。

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

我在安装构建包后再次部署了PS。

在Heroku上出错。无法启动Chrome
