Describe the Bug

Observed behavior

Error on starting a simple bare-bones app.

Expected behavior

It should start normally.

Steps to reproduce

Just follow the instruction on https://developers.cloudflare.com/workers/frameworks/framework-guides/nuxt

• npm create cloudflare@latest my-nuxt-app -- --framework=nuxt --experimental
• cd my-nuxt-app
• npm run dev

This fails.

Note that npm run build succeeds. But then, npx wrangler dev fails.

Code

Here is the auto-generated wrangler.toml

#:schema node_modules/wrangler/config-schema.json
name = "my-nuxt-app"
compatibility_date = "2024-10-04"
main = "./dist/worker/index.js"
assets = { directory = "./dist/public", binding = "ASSETS" }

Hmm don't think this is specific to Nuxt but this is a workerd exception on Windows.

See the error message shown when you hit the error:

On Windows, this may be caused by an outdated Microsoft Visual C++ Redistributable library.

See https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist.

Have you tried this?

[ManasMadrecha]

The Windows error might prop up on npx wrangler dev, but why is the first command of npm run dev itself showing an error that workerd unable to initialise worker bindings or so? 😯

I've a Nuxt 3 app running on CF Pages nicely. But I wanted to try the new option available on running the framework on workers as well.

[penalosa]

@ManasMadrecha to clarify, have you tried updating the Microsoft Visual C++ Redistributable library? What version are you on?

[ManasMadrecha]

Yes, updated that and now it's working. 😯 Seemed like a pretty easy solution, but don't know why it was an issue in the first place 🙏🏻
