Describe the Bug

When I use create astro CLI to create a new project，by step 2, yarn/npm/pnpm run dev, I got the Error like this:

Error: astro tried to access shikiji-core, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.

Required package: shikiji-core (via "shikiji-core/package.json")
Required by: astro@npm:4.2.8 (via /Users/xxx/.yarn/berry/cache/astro-npm-4.2.8-b761f9a737-10c0.zip/node_modules/astro/dist/core/config/schema.js)

at makeError (/Users/xxx/Documents/learn/astro/hello-astro/.pnp.cjs:11499:34)
at resolveToUnqualified (/Users/xxx/Documents/learn/astro/hello-astro/.pnp.cjs:13147:21)

at resolve$1 (file:///Users/xxx/Documents/learn/astro/hello-astro/.pnp.loader.mjs:1993:31)

When I install "shikiji-core" myself, the error was resolved.

What's the expected result?

Start server normally

add "shikiji-core" into the package.json

Yeah it should be in dependencies instead of devDependencies. Feel free to send a PR for that!

If someone needs a temporary workaround using yarn, I'm leaving this code here. Add a .yarnrc.yml file to the root of your project. Include the below code:

packageExtensions: {
  astro@4.3.1: {
    dependencies: {
      shikiji-core: "^0.9.18"
    }
  }
}

After adding the file, run yarn install. Then yarn build or yarn dev should work fine.

I faced this issue with Astro v4.3.1. You can update astro's version to be specific to what you are using.
Also shikiji-core's version has been picked from the pull request above.

Once this is fixed in Astro's next release, the .yarnrc.yml file or at least the above lines can be safely removed from this file.

P.S.: Possibly, your first thought would be to use yarn patch. However, the dependencies are computed at fetch time and not at resolution time. Hence packageExtensions is the way to go.
