As you can from the error, you have an issue with your dependencies, which you need to fix manually. Astro won't do that for you.

@ematipico So this issue is coming from a fresh new Astro project, what is the dependencies with Astro?

[jamesli2021]

So deno adapter is having issue.

Astro project looks fine. package.json

{
  "name": "cosmic-cluster",
  "type": "module",
  "version": "0.0.1",
  "scripts": {
    "dev": "astro dev",
    "start": "astro dev",
    "build": "astro check && astro build",
    "preview": "astro preview",
    "astro": "astro"
  },
  "dependencies": {
    "astro": "^4.3.2",
    "@astrojs/check": "^0.4.1",
    "typescript": "^5.3.3"
  }
}
