Symfony 6.4中eckinox/pdf-bundle调用Puppeteer启动浏览器失败

问题详情 #

使用Symfony 6.4的eckinox/pdf-bundle生成PDF时，调用执行Puppeteer的Node脚本失败。将脚本简化为仅获取Chrome版本的测试代码，仍出现相同错误。直接在命令行执行该脚本一切正常，且PHP的exec调用与命令行使用相同用户、环境变量和权限。

简化测试脚本 #

const puppeteer = require('puppeteer');

(async()=>{const x = require("puppeteer"); console.log(await(await(await x.launch()).newPage()).browser().version())})()

排查建议 #

• 添加无沙箱启动参数：PHP执行环境通常缺少完整的沙箱权限，在launch()中添加参数绕过：

  await x.launch({ args: ['--no-sandbox', '--disable-setuid-sandbox'] })
  

• 手动指定浏览器路径：避免环境路径差异导致找不到浏览器，直接指定Chrome/Chromium的绝对路径：

  await x.launch({ executablePath: '/usr/bin/chromium-browser' }) // 路径根据实际环境调整
  

• 输出详细启动日志：修改脚本添加错误捕获和日志输出，定位具体启动失败原因：

  const puppeteer = require('puppeteer');
  
  (async() => {
    try {
      const browser = await puppeteer.launch({
        args: ['--no-sandbox', '--disable-setuid-sandbox'],
        dumpio: true // 输出浏览器启动的所有控制台日志
      });
      const page = await browser.newPage();
      console.log(await browser.version());
      await browser.close();
    } catch (error) {
      console.error('启动失败详细错误:', error);
    }
  })()
  

• 检查系统权限限制：排查服务器的SELinux、AppArmor是否阻止了浏览器进程启动，同时确认PHP的exec函数是否有进程数、内存等资源限制。
