Error: write EPIPE when using wrangler dev to run cloudflare worker using itty-router

[zztkm]

Issue

When I do what the quick start says, I get the following error when I run make dev

My Environment

• Ubuntu 22.04.2 LTS (GNU/Linux 5.15.90.1-microsoft-standard-WSL2 x86_64)

Error

❯ make dev
wrangler dev
 ⛅️ wrangler 3.0.1
------------------
wrangler dev now uses local mode by default, powered by 🔥 Miniflare and 👷 workerd.
To run an edge preview session for your Worker, use wrangler dev --remote

Solution

I was able to solve the problem by installing libc++1.

apt install libc++1

This seems to be an issue with Wrangler and the workerd, but I'll leave this issue open for now as it may be helpful to the users of syumai/workers. Thanks @zztkm!

I encountered the same issue on Ubuntu 20.04 / WSL2 / Node.js v18.16.1. Trying to install libc++1 did not solve it...

@wdssmq The cause is not known, but updating to Ubuntu 22.04 may solve the problem...
