Bug

After installing OpenClaw via npm, the memory-lancedb plugin fails with:

memory-lancedb: failed to load LanceDB. Error: Cannot find module '@lancedb/lancedb'
Require stack:
- /usr/lib/node_modules/openclaw/extensions/memory-lancedb/index.ts

Cause

extensions/memory-lancedb/package.json lists @lancedb/lancedb as a dependency, but it's not installed in node_modules after npm install -g openclaw.

Likely because the monorepo uses pnpm workspaces and the dependency doesn't get hoisted/bundled when publishing to npm.

Workaround

cd /tmp && npm install @lancedb/lancedb
cp -r /tmp/node_modules/* /usr/lib/node_modules/openclaw/extensions/memory-lancedb/node_modules/
openclaw gateway restart

Environment

• OpenClaw: 2026.2.23
• Node: v22.22.0
• OS: Ubuntu Linux 6.8.0-100-generic (x64)
• Install method: npm global
