使用Playwright在集群部署时无法启动浏览器的问题求助

我尝试以Docker镜像形式将Playwright部署到集群中，本地系统运行一切正常，但部署到Pod中后立即出现如下错误：

1) [webkit] › dummy.spec.js:7:8 › API Designer › Should display data in All Services =============

browserType.launch: Failed to launch: Error: spawn /opt/app/node_modules/@playwright/test/node_modules/playwright-core/.local-browsers/webkit-1699/pw_run.sh ENOENT
=========================== logs ===========================
<launching> /opt/app/node_modules/@playwright/test/node_modules/playwright-core/.local-browsers/webkit-1699/pw_run.sh --inspector-pipe --headless --no-startup-window
[pid=N/A] starting temporary directories cleanup
[pid=N/A] finished temporary directories cleanup
============================================================

    at Object._baseTest.extend.browser.scope [as fn] (/opt/app/node_modules/@playwright/test/lib/index.js:226:51)
    at /opt/app/node_modules/@playwright/test/lib/fixtures.js:112:81

我通过Node.js运行测试，代码如下：

const { exec } = require("child_process");
exports.runTests = async () => {
const proc = exec(
    `DEBUG=pw:browser* PLAYWRIGHT_BROWSERS_PATH=./node_modules/@playwright/test/node_modules/playwright-core/.local-browsers npx playwright test`,
    (error, stdout, stderr) => {
      if (error) {
        console.log(`error : ${error}`);
      }
      if (stderr) {
        console.log(`error : ${stderr}`);
      }
    }
  );
  proc.stdout.pipe(process.stdout);
};

• 确保容器内完整安装浏览器及依赖：错误提示找不到pw_run.sh，说明容器中Playwright的浏览器包未正确安装。本地环境可能依赖宿主机文件，但容器需要独立安装。在Dockerfile中添加命令：

  RUN npx playwright install --with-deps webkit
  

  该命令会自动下载WebKit二进制文件并安装所有系统依赖库。

• 移除硬编码的浏览器路径：你手动指定的PLAYWRIGHT_BROWSERS_PATH在容器环境中可能无效。Playwright默认会自动管理浏览器路径，直接去掉该环境变量，使用默认路径即可：

  const proc = exec(
      `DEBUG=pw:browser* npx playwright test`,
      // ... 其余代码不变
  );
  

• 使用Playwright官方基础镜像：官方镜像（如mcr.microsoft.com/playwright:v1.38.0-focal）已预装所有浏览器和系统依赖，无需手动配置环境。直接基于该镜像构建你的应用镜像，能避免大部分环境依赖问题。

• 检查文件执行权限：Pod运行用户可能没有pw_run.sh的执行权限。可在Dockerfile中添加权限设置：

  RUN chmod -R +x /opt/app/node_modules/@playwright/test/node_modules/playwright-core/.local-browsers/
  

• 确认容器工作目录一致性：确保Dockerfile中设置的工作目录与你代码中相对路径匹配，比如通过WORKDIR /opt/app指定工作目录，避免路径解析错误。
