Failed to install gitnexus: {result.get('output', '')}

Error message

Failed to install gitnexus: {result.get('output', '')}

What it means

Thrown by _install_gitnexus() in eval/environments/gitnexus_docker.py when `npx gitnexus --version` reports NOT_FOUND and the subsequent `npm install -g gitnexus` (60s timeout) returns non-zero. The message includes npm's output so you can diagnose registry/network/package errors.

Solutions

1. Pre-install gitnexus in the Docker image: `RUN npm install -g gitnexus` at build time so the eval path is a no-op.
2. Increase the per-step timeout (currently 60s) — global npm install can exceed it on slow links.
3. Verify registry connectivity: `docker run --rm <image> bash -lc 'npm ping; npm view gitnexus version'`.
4. If a corporate npm registry is configured, ensure gitnexus is mirrored there, or override npm_config_registry for the install.
5. Clear the npm cache (`npm cache clean --force`) or rebuild the image to fix a corrupted cache.

Example fix

# before: install at eval time, 60s cap
result = self.execute({'command': 'npm install -g gitnexus', 'timeout': 60})

# after: raise timeout, and pre-bake in Dockerfile
result = self.execute({'command': 'npm install -g gitnexus', 'timeout': 300})
# Dockerfile: RUN npm install -g gitnexus@<pinned-version>

# Preflight: confirm npm registry is reachable from the container
docker run --rm "$IMAGE" bash -lc 'npm ping && npm view gitnexus version'

    else:
        raise

When it happens

Trigger: Container has Node but no gitnexus; the global `npm install -g gitnexus` fails (non-zero returncode). Example: npm registry unreachable, 60s timeout exceeded on slow networks, npm cache corruption, or a transient registry 5xx.

Common situations: Eval container with no outbound npm access; npm registry rate-limiting CI (429); slow network blowing the 60s timeout; npm cache broken inside the image; npm config pointing at a private registry that lacks gitnexus.
