No files were copied from Cloudflare component directory

Error message

No files were copied from Cloudflare component directory

What it means

After copying a Cloudflare sandbox component's files into the sandbox directory, the installer re-reads the destination with fs.readdir and asserts it is non-empty. An empty result means the copy loop matched nothing (source dir empty, filter mismatch, or silent copy failures), so it aborts rather than proceeding with a broken sandbox.

Solutions

1. Verify the component directory actually contains files: ls cli-tool/components/sandbox/cloudflare/<name>/ in the repo
2. If files are missing upstream, reinstall the latest CLI (npx claude-code-templates@latest) so the package bundles a complete catalog
3. Report/fix the component so its folder ships with its files, then regenerate components.json and republish
4. If the source truly has no extra files but the install is valid, guard the emptiness check on the specific copy operation rather than the whole dir

Example fix

// before
const copiedFiles = await fs.readdir(sandboxDir);
if (copiedFiles.length === 0) {
  throw new Error('No files were copied from Cloudflare component directory');
}
// after — only count files the copy step itself produced
const copiedFiles = (await fs.readdir(sandboxDir)).filter(f => copiedSet.has(f));
if (copiedFiles.length === 0) {
  throw new Error(`No matching files copied from ${componentsDir} (filter mismatch)`);
}

const entries = await fs.readdir(componentsDir).catch(() => []);
if (entries.length === 0) { console.error(`Component dir empty: ${componentsDir}`); process.exit(1); }

try { /* install */ } catch (e) { if (/No files were copied/.test(e.message)) { console.warn('Component package incomplete — update the CLI: npx claude-code-templates@latest'); process.exit(1); } throw e; }

When it happens

Trigger: Installing a Cloudflare sandbox component (`--sandbox cloudflare-<name>`) where the component's directory exists but contains no files matching the copy filter, or where the packaged/extracted components directory is empty.

Common situations: The npm package was published with the cloudflare component folder empty due to .gitignore/.npmignore rules; the component was renamed/deleted upstream while the catalog still lists it; the extracted temp dir was cleaned mid-install.
