## 2. Sidebar (Navigation)
* **Header:** Log
* **Run ID:** No.1 run
* **Task List:**
* **Clone:** Completed (Green checkmark), 19s
* **Auto Node Cache:** Completed (Green checkmark), 01s
* **run emo pipeline:** Failed (Red 'x' icon), 12s. *This item is highlighted with a yellow box.*

## 3. Main Analysis Panel (Header & RCA)
* **Title:** run emo pipeline
* **Status Summary:** 共发现 1 个问题 (Translation: A total of 1 problem was found).
* **Controls:** 解构模式 (Deconstruction Mode), 收起 (Collapse).
### Section: Error & Key Log (Yellow Box 2)
* **Error:** [可能性较大] pnpm install 命令执行失败，原因为当前Node.js版本 (v16.20.2) 低于 /commander/12.1.0 包所需的Node.js版本 (>=18)。
* *Translation:* [High Probability] The `pnpm install` command failed because the current Node.js version (v16.20.2) is lower than the Node.js version (>=18) required by the `/commander/12.1.0` package.
* **Key Log:** 1. 日志行: 38-46 pnpm install 命令执行失败，原因为当前Node.js版本过低，与 /commander/12.1.0 包所需的Node.js版本不兼容。
* *Translation:* 1. Log lines: 38-46. The `pnpm install` command failed because the current Node.js version is too low and incompatible with the Node.js version required by the `/commander/12.1.0` package.
### Section: Solution (Yellow Box 3)
1. **Option 1:** 升级 node.js 版本 如果本地 node.js 版本 >= 18.12，请尝试与本地 node.js 保持相同的版本，你可以尝试从 CI Docker Images 推荐使用镜像 中找到指定版本的官方包。
* *Translation:* Upgrade Node.js version. If the local Node.js version is >= 18.12, please try to maintain the same version as the local Node.js. You can try to find the official package of the specified version from the "Recommended CI Docker Images".
2. **Option 2:** 降级 pnpm 版本 根据 bnpm FAQ | bnpm 问题速查 内容，当 node.js 的版本 < 20 时，可以选择将 pnpm 的版本降级至 8.x latest，你可以查看文档找到具体的操作方法。
* *Translation:* Downgrade pnpm version. According to bnpm FAQ | bnpm Quick Search, when the Node.js version is < 20, you can choose to downgrade the pnpm version to 8.x latest. You can check the documentation for specific operation methods.
3. **Option 3:** 锁定版本 根据 check 阶段 pnpm install 失败？生产用的都是 pnpm@7，但是看check 阶段的确是 pnpm@8? 内容，可能是pnpm版本导致的，可以尝试锁定版本。具体方法可以参考参考链接_4。
* *Translation:* Lock version. Based on "pnpm install failed during check stage? Production uses pnpm@7, but the check stage is indeed pnpm@8?", it might be caused by the pnpm version. You can try locking the version. Refer to Reference Link 4 for specific methods.
### Action Buttons (Yellow Box 4)
