Cloudflare create-cloudflare fails with ERR_PNPM_IGNORED_BUILDS on pnpm 10/11

What this error means

ERR_PNPM_IGNORED_BUILDS on pnpm 10/11 during create-cloudflare scaffolding is a Cloudflare failure pattern reported for developers trying to fix cloudflare workers scaffolding failing with err_pnpm_ignored_builds when using pnpm 10 or 11. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

GitHub issue #13928 filed 2026-05-15 against cloudflare/workers-sdk. Running ‘pnpm create cloudflare@latest’ on pnpm >= 10 fails with ERR_PNPM_IGNORED_BUILDS. This blocks new Cloudflare Workers project creation for pnpm users.

Common causes

• GitHub issue #13928 filed 2026-05-15 against cloudflare/workers-sdk. Running ‘pnpm create cloudflare@latest’ on pnpm >= 10 fails with ERR_PNPM_IGNORED_BUILDS. This blocks new Cloudflare Workers project creation for pnpm users.

Quick fixes

1. Confirm the exact error signature matches ERR_PNPM_IGNORED_BUILDS on pnpm 10/11 during create-cloudflare scaffolding.
2. Check the Cloudflare account, local tool state, and provider configuration involved in the failing workflow.
3. 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

1. Capture the exact error message and the command, editor action, or request that triggered it.
2. Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
3. Review the source evidence below and compare it with your environment.
4. Apply one change at a time and rerun the smallest failing action.
5. 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.
