What this error means
EACCES: permission denied — mkdir /usr/local/lib/node_modules/.npm/_cacache/tmp or node_modules during npm install global package in Docker/container is a Docker failure pattern reported for developers trying to fix docker eacces permission denied errors when installing global npm packages or running build scripts inside containers. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.
Why this happens
Widespread error across AI coding tools and DevOps workflows: openclaw README documents EACCES permission denied during npm install -g; MicroClaw reports Permission denied (os error 13) on SDK binary startup; OmniRoute wiki covers EACCES data directory issues. Distinct from already-covered Docker bind/port-permission errors on dev-error-db. Strong commercial value affecting containerized CI/CD pipelines.

Quick fixes
- Confirm the exact error signature matches
EACCES: permission denied — mkdir /usr/local/lib/node_modules/.npm/_cacache/tmp or node_modules during npm install global package in Docker/container. - Check the Docker account, local tool state, and provider configuration involved in the failing workflow.
- Compare the failing environment with a known working setup, then change one configuration value at a time.
Platform/tool-specific checks
- Verify the command, editor, extension, or API client that produced the error.
- Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
- Avoid deleting credentials, local model data, or project settings until the failing scope is clear.
Step-by-step troubleshooting
- Capture the exact error message and the command, editor action, or request that triggered it.
- Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
- Review the source evidence below and compare it with your environment.
- Apply one change at a time and rerun the smallest failing action.
- Keep the working fix documented for the team or deployment environment.
How to prevent it
- Keep provider/tool configuration documented.
- Record non-secret diagnostics such as tool version, provider name, model name, and command path.
- Add a lightweight check before CI or production workflows depend on the tool.
