Describe the Bug

I just followed the tutorial from https://developers.cloudflare.com/workers/get-started/guide/, on the part of installing wrangler. I ran npx wrangler dev in my directory worker folder and got error of

<my-project-worker-path>/node_modules/@cloudflare/workerd-linux-64/bin/workerd: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found <my-project-worker-path>/node_modules/@cloudflare/workerd-linux-64/bin/workerd)

I have tested

sudo apt update
sudo apt install libc6

But still not working

Please provide any relevant error logs

Error on my terminal

I got warning previously before I did the npx wrangler dev

npm warn deprecated rollup-plugin-inject@3.0.2: This package has been deprecated and is no longer maintained. Please use @rollup/plugin-inject.
npm warn deprecated sourcemap-codec@1.4.8: Please use @jridgewell/sourcemap-codec instead

Then the following error during npx wrangler dev

<my-project-worker-path>/node_modules/@cloudflare/workerd-linux-64/bin/workerd: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found <my-project-worker-path>/node_modules/@cloudflare/workerd-linux-64/bin/workerd)

I successfully built it using the node:22.13.1-bookworm Docker image.

I am getting the same error on the same WSL setup (Ubuntu 20.04). As it turns out, the version of libc that's installable through Ubuntu's package system on 20.04 is libc6 2.31:

$ apt-get -s install libc6
...
libc6 is already the newest version (2.31-0ubuntu9.16).
...

Since workerd requires 2.32, this effectively drops support for Ubuntu 20.04. The good news is that Ubuntu 22.04 and beyond supports libc6 2.35, so upgrading to a newer version of Ubuntu (or installing it alongside your existing 20.04 install) should fix the problem.

[Edit] I can confirm that upgrading to Ubuntu 22.04, using the instructions here, the error is gone. The same is true after upgrading further to Ubuntu 24.04

Similar issue on RHEL9 since Wrangler 3.105.1:

/.../node_modules/@cloudflare/workerd-linux-64/bin/workerd: /lib64/libc.so.6: version `GLIBC_2.35' not found (required by /.../node_modules/@cloudflare/workerd-linux-64/bin/workerd)

Latest glibc for RHEL9 is ldd --version:

ldd (GNU libc) 2.34

which basically means that projects using Wrangler/workerd kind of stuck now with version 3.105.0, as there is no RHEL10 release yet. Not to mention the time an enterprise probably requires to migrate a build intrastructure from 9 to 10 once it's available.

However, I would understand such a change in OS support with a new Wrangler major release. But here it's a minor release (even a patch).
