Issue Checklist\n\n- [x] I have searched through the existing issues and did not find a similar report.\n- [x] I have provided a short and descriptive title.\n\n### Platform\n\nmacOS\n\n### Version\n\nv1.7.24\n\n### Bug Description\n\nOpenClaw 一键安装在 macOS 上失败。安装过程中出现两个错误：\n\n1. 第一次 npm 安装失败（exit code 243）：Electron 内部 spawn 的 npm 进程异常退出\n2. sudo 重试失败（exit code 127）：@expo/sudo-prompt 提权后，root 的 PATH 不包含 nvm/homebrew 路径，导致 env: node: No such file or directory\n\n### Root Cause\n\nOpenClawService.ts 中构造 sudo 命令时，没有将 node 所在目录注入 PATH：\n\ntypescript\n// 当前代码\nconst npmCommand = `\"${npmPath}\" install -g openclaw@latest`\n// npm 的 shebang 是 #!/usr/bin/env node\n// sudo 环境的 PATH 只有 /usr/bin:/bin:/usr/sbin:/sbin\n// 找不到 node → env: node: No such file or directory\n\n\n### Fix\n\n在 sudo 命令前注入 node 目录到 PATH：\n\ntypescript\nconst nodeDir = path.dirname(npmPath)\nconst npmCommand = `export PATH=\"${nodeDir}:$PATH\" && \"${npmPath}\" install -g openclaw@latest`\n\n\n### Error Log\n\n\nInstalling OpenClaw with command: /usr/local/bin/npm install -g openclaw@latest\nOpenClaw install failed with code 243\nPermission denied, retrying with sudo-prompt...\nSudo install failed: Command failed: \"/usr/local/bin/npm\" install -g openclaw@latest\nenv: node: No such file or directory\n\n\n### Environment\n\n- macOS with nvm (node v24.14.0) + homebrew (node v25.8.0)\n- npm shebang: #!/usr/bin/env node\n- @expo/sudo-prompt uses osascript, root PATH doesn't include nvm/homebrew dirs\n\n### PR\n\n#13356
