编程这一路

直接看一开始的 Error 还以为是网络问题没法下载 chrome ,尝试设置了 PUPPETEER_SKIP_CHROMIUM_DOWNLOAD 没用
,后来才看见底下的 permission denied 原来是没权限

运行 sudo npm i puppeteer 安装即可

经过翻看 issues 这个问题是因为依赖问题导致的

执行 wget -qO- --no-check-certificate https://raw.githubusercontent.com/Garbee/puppeteer/cd00f7d936c942f8f378a332401024e501b186ce/utils/linux/debian-check.sh | bash 后,在 shell 执行列出的命令,安装相关依赖。

设置 --no-sandbox 参数:

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

或者切换到非 root 用户
