按照文档“https://memos-claw.openmem.net/docs/index.html#config”的流程安装openclaw的插件，重启gateway时报错错了：

我本地按 issue 里的步骤做了隔离复现，确认这不是单纯的本地环境偶发问题。

现象是：
openclaw plugins install @memtensor/memos-local-openclaw-plugin 可以返回安装成功，但插件目录里不一定会生成 better-sqlite3 需要的原生绑定文件，后面 gateway 加载插件时就会报 Could not locate the bindings file。

继续往下排查后，根因更像是安装链路和插件实现之间有冲突：

1. OpenClaw 安装插件时会用 npm install --ignore-scripts。
2. better-sqlite3 依赖安装阶段生成原生绑定。
3. 当前插件虽然有 bootstrap / rebuild 的兜底逻辑，但入口文件仍然在模块顶层直接依赖了 better-sqlite3。这样一来，只要绑定缺失，实际会在进入兜底逻辑之前先报错。

我这边本地验证过，安装完成后手动执行下面这条命令可以恢复正常：

cd ~/.openclaw/extensions/memos-local-openclaw-plugin
npm rebuild better-sqlite3

所以目前看下来，这个问题的核心不是“用户没装编译环境”这么简单，而是：
插件运行依赖 better-sqlite3 的 native binding，但 OpenClaw 的插件安装流程默认又跳过了这类依赖常用的安装脚本，导致“安装成功”和“实际可用”被分开了。

短期建议至少先把文档和报错提示写得更明确一些，避免继续误导用户：

• 明确写出 OpenClaw 插件安装阶段会忽略 npm scripts
• 明确写出遇到这个报错时需要手动执行 npm rebuild better-sqlite3
• 明确写出支持的 OpenClaw / Node 版本范围

如果需要，我可以再补一份更细的复现步骤和本地排查记录。
