Version

0.1.4

Platform

Linux olyno-PC 5.10.101-amd64-desktop #20.00.05.06-release SMP Mon Mar 14 09:34:55 CST 2022 x86_64 GNU/Linux

What steps will reproduce the bug?

Here are my steps to reproduce the error:

docker pull jarredsumner/bun:edge
docker run -it --rm --init --ulimit memlock=-1:-1 jarredsumner/bun:edge
bun create next ./next-bun

How often does it reproduce? Is there a required condition?

No response

What is the expected behavior?

Creating a NextJS project with Bun without error

What do you see instead?

Fetching package.json... error: Linux kernel version doesn't support io_uring, which Bun depends on. 

To fix this error: please upgrade to a newer Linux kernel.

If you're using Windows Subsystem for Linux, here's how: 
  1. Open PowerShell as an administrator
  2. Run this:
    wsl --update
    wsl --shutdown

If that doesn't work (and you're on a Windows machine), try this:
  1. Open Windows Update
  2. Download any updates to Windows Subsystem for Linux

If you're still having trouble, ask for help in bun's discord https://bun.sh/discord

I get the same error

Very helpfull on it's own

Reproduction:

I can provide additional info if needed

You must update kernel to latest version.

[Olyno]

Updating the kernel to the latest version can literally break the whole OS we're using. It's definitely not recommended.

Io_uring requires kernel 5.1>

[shiftgeist]

I suggest adding a check in the install script

[Coachonko]

Container images do not ship with the linux kernel. Containers share the kernel of the host OS. If the host of the container does not have io_uring support, such as any kernel <5.1 and kernels >5.1 with io_uring disabled, then io_uring won't be available in the container.

If your host OS does not have io_uring support, instead of using a container I recommend running a kernel-based virtual machine running an OS with io_uring support.

This is a serious problem with Bun, I don't think it can be solved easily. RHEL is one major distribution, particularly on servers, and it ships with io_uring disabled despite the kernel being >5.14 on version 9.

So what should I do? How to run Bun on WSL2?

[Electroid]

Older releases of Bun used to depend more heavily on io_uring, like for bun install and fetch(). Not anymore, though we will still keep this open so we can implement nice fallbacks.
