Bun remains usable as an optional dependency installer and package-script runner. The default package manager remains pnpm, which is fully supported and used by docs tooling. Bun cannot use pnpm-lock.yaml and ignores it.
Install
`bun.lock` / `bun.lockb` are gitignored, so there is no repo churn. To skip lockfile writes entirely:
```sh
bun install --no-save
```
Commands that launch OpenClaw itself must still run through Node.
Lifecycle scripts
Bun blocks dependency lifecycle scripts unless explicitly trusted. For this repo, the commonly blocked scripts are not required:
baileyspreinstall: checks Node major >= 20 (OpenClaw requires Node 22.22.3+, 24.15+, or 25.9+, with Node 24 recommended)protobufjspostinstall: emits warnings about incompatible version schemes (no build artifacts)
If you hit a runtime issue that needs these scripts, trust them explicitly:
bun pm trust baileys protobufjs
Caveats
Some package scripts hardcode pnpm internally (for example check:docs, ui:*, protocol:check). Running them via bun run still shells out to pnpm, so just run those via pnpm directly.
