Hello guys, we have a slight issue here:
I believe I am running version 0.2.30, which has a bug:

Error: No suitable shell found. Claude CLI requires a Posix shell environment. Please ensure you have a valid shell installed and the SHELL environment variable set.

according to this: Can't find $SHELL even though it exists · Issue #330 · anthropics/claude-code · GitHub , the workaround is to use latest version: 0.2.32

this seems to be resolvable with an overlay, my question is, if i can solve this myself, how do i upstream the latest version to nixpkgs so that nix folks who build from unstable channel will have version 0.2.32

thanks

Hi!

I think you could open up a PR to update it, looking at the files here: claude-code: init at 0.2.9 by malob · Pull Request #384860 · NixOS/nixpkgs · GitHub .

It looks like you’ll need to get the new hash and bump the version number. You might also see about adding yourself as a maintainer if you’d like. Then, tag the existing maintainers to review your PR. :slight_smile:

hi,
its already done, i successfully applied overlay to run locally using nix-shell:

alice7@nixos ~/.d/c/claude-code> claude --version
0.2.32 (Claude Code)

i will be looking into the details of how to apply for PR. thanks for the information.

Thanks for packaging this! It gives claude shell access, so I figured I’d at least run it in its own userspace and restrict its access. Not bulletproof, but forces me to always diliberately grant it access to things rather than trusting it to do the right thing:

    systemd.tmpfiles.rules = [
      "d /srv/src 0775 root users - -"
    ];

Here’s my user definition:

      users.users.ai = {
        isNormalUser = true;
        packages = with pkgs; [
          unstable.claude-code
          unstable.aider-chat
          nodejs_20
          yarn
          deno
          python311
          python311Packages.pip
          python311Packages.ipython
        ];
      };

Thus in practice here’s how I start a project and run the agent:

doas su - ai
cd /srv/src
npm init vite myproject
claude

In my shell config for the agent I set umask 002 so that the default permissions of files that it creates are group writable. That way I can still directly collaborate with the agent and review its changes using my IDE.
