openclaw - 💡(How to fix) Fix [Bug] sqlite-vec package not found after v2026.4.27 upgrade — memory vector search broken [1 comments, 2 participants]

1. memory_search calls vector similarity — error logged

TL;DR

Manually installing sqlite-vec or patching the import path in engine-storage*.js may resolve the vector similarity ranking issue.

Guidance

• Verify that sqlite-vec is not present in plugin-runtime-deps/.../node_modules/ before attempting a fix.
• Consider adding sqlite-vec as an explicit dependency in the plugin-runtime-deps package to ensure it is bundled and shipped correctly.
• If manual installation is preferred, run npm install sqlite-vec in the ~/.openclaw/plugin-runtime-deps/openclaw-2026.4.27-*/ directory and restart the gateway.
• To patch the import path, update engine-storage*.js to use require('sqlite-vec/index.cjs') instead of require('sqlite-vec').

Example

// engine-storage*.js
const sqliteVec = require('sqlite-vec/index.cjs'); // updated import path

Notes

The issue is specific to OpenClaw v2026.4.27 and may not affect other versions. The suggested fixes assume that the sqlite-vec package is compatible with the current Node.js version (v25.8.2).

Recommendation

Apply the workaround by manually installing sqlite-vec using npm install sqlite-vec in the affected directory, as this is a quicker solution than patching the import path or adding sqlite-vec as a dependency.
