It works just fine on a different non-WSL2 Linux VM!

ubuntu@instance-20211204-1555:~$ bun -v
1.3.1

After installation of latest version I had this error:

Ubuntu 22.04
Tried to install sudo apt install -y musl, than codex stopped loading at all. No errors. Downgraded to 0.53 and it work again

Same issue, downgrade to 0.53.0 works.

What was the problem:

  • The npm package uses musl-compiled Linux binaries (x86_64-unknown-linux-musl)
  • WSL2 runs Ubuntu with glibc 2.39, not musl
  • The musl binary was incompatible and segfaulted

Solution:
Downloaded the codex-x86_64-unknown-linux-gnu.tar.gz (glibc version) from GitHub releases and replaced the musl binary at:
/home/ilya/.nvm/versions/node/v24.7.0/lib/node_modules/@openai/codex/vendor/x86_64-unknown-linux-musl/codex/codex
