The same repo deploys elsewhere but fails on Cloudflare Pages.

What to check first

Platform: Cloudflare Pages
Error: Build command failed

Cloudflare Pages build failures are often a preset, output directory, or Node version mismatch. Confirm the exact build command and output folder your framework produces.

Step-by-step fix

Check Pages ? Settings ? Builds & deployments for Build command and Build output directory.
For Vite use npm run build and dist; for many static builds the output is dist or build, not public.
Set NODE_VERSION if your project requires a newer Node release.
Add missing secrets in Environment variables and redeploy with a cleared build cache if needed.

# Vite example
Build command: npm run build
Build output directory: dist

# package.json
{ "scripts": { "build": "vite build" } }

Common mistake to avoid

Do not change code before checking the output directory. A correct build with the wrong output folder still fails deployment.
