Question

寻求专家的帮助。从终端运行Puppeteer时，它可以按预期运行并生成pdf文件（脚本的一部分为const browser = await puppeteer.launch();）

通过shell运行会生成pdf文件

$ /bin/sh /tmp/grafana_report_pup.sh

grafana_report_pup.sh

node /tmp/grafana_pdf.js http://localhost:3000/d/qP-sbQEZz/new-dashboard?kiosk $GF_USER:$GF_PASSWORD $GF_OUT

问题出现在我放入crontab时：

# m h  dom mon dow   command
44 10 * * * /bin/sh /tmp/grafana_report_pup.sh  > /tmp/graf.log 2>&1

我收到有关没有沙箱的错误，因此建议我传递参数：

const browser = await puppeteer.launch({args: ['--no-sandbox', '--disable-setuid-sandbox']});

即使使用建议的参数，从crontab运行也会产生以下错误
