@littledivy IIRC you hit similar problem a few days ago in another package.

Yup, i hit this a few days ago with npm:create-astro itself.

Did some debugging, it turns out create-astro is not waiting for files to be written before reading it in the Typescript initialization step.

https://github.com/withastro/astro/blob/7eac778cce4429059d433fa22bf8f44555e2965f/packages/create-astro/src/actions/template.ts#L62-L70

// Match first indent in the file or fallback to `\t`
const indent = /(^\s+)/m.exec(value)?.[1] ?? '\t';
-fs.promises.writeFile(
+return fs.promises.writeFile(
  file,
  JSON.stringify(
	Object.assign(JSON.parse(value), Object.assign(overrides, { private: undefined })),
	null,
	indent
  ),
  'utf-8'
);

This patch fixes deno run -A create-astro@latest
