@codex 根据用户提供的日志 定位问题原因

[chatgpt-codex-connector]

Summary

• 根据日志与代码路径判断，失败根因是 Docker 运行用户与浏览器缓存路径不一致 + 运行阶段未确保浏览器二进制可用：scraper 在 Docker 中直接调用 p.chromium.launch(...)，依赖 Playwright 自动解析浏览器可执行文件路径；一旦路径下没有对应版本（如 chromium_headless_shell-1208），就会抛出你日志中的 Executable doesn't exist。src/scraper.py 中未显式指定 executable_path，因此完全依赖 Playwright 的默认浏览器目录。. src/scraper.pyL523-L530
• 我已在 Dockerfile 做修复：将 PLAYWRIGHT_BROWSERS_PATH 改为固定目录 /ms-playwright，避免 /root 与 appuser 主目录差异导致的路径漂移。. DockerfileL37-L40
• 在最终运行镜像阶段补充 playwright install chromium，确保容器实际运行层内有与当前 Playwright 匹配的浏览器可执行文件。. DockerfileL45-L61
• 删除了从 builder 拷贝 /root/.cache/ms-playwright 的做法，并把 /ms-playwright 目录授权给 appuser，避免“安装在 root 路径、运行在非 root 用户”带来的访问与版本不一致问题。. DockerfileL73-L78
• 已完成提交：96ad19a（fix(docker): ensure playwright browsers are installed for runtime user），并已按要求创建 PR（增量说明已写入 PR 标题与正文）。

Testing

• ✅ pwd && rg --files -g 'AGENTS.md'
• ✅ rg -n "playwright|BrowserType.launch|chromium|ms-playwright|install" Dockerfile* docker* src spider_v2.py start.sh requirements*.txt pyproject.toml package*.json
• ✅ nl -ba Dockerfile | sed -n '1,220p'
• ✅ nl -ba src/scraper.py | sed -n '470,560p'
• ⚠️ python - <<'PY' ... requests.get('https://playwright.dev/python/docs/browsers') ...（环境代理返回 403，无法联网检索外部网页）
• ⚠️ docker compose -f docker-compose.dev.yaml config >/tmp/compose-config.out && echo OK（当前环境无 Docker CLI：command not found: docker）
