2. Add to ~/.config/nushell/env.nu

let mise_path = $nu.default-config-dir | path join scripts mise.gen.nu
^mise activate nu | save --force $mise_path

1 problem found:

1. mise is not activated, run mise help activate or
   read documentation at https://mise.jdx.dev for activation instructions.
   Alternatively, add the shims directory ~/.local/share/mise/shims to PATH.
   Using the shims directory is preferred for non-interactive setups.

Additional context
Add any other context about the problem here. Consider running mise with --debug or --trace for extra debug info.

Looks like it could possibly be due to this change:
nushell/nushell@fce6146
...which (rightly or wrongly) causes $env.config.hooks.env_change to be empty.

I am assuming this is a bug in nushell 0.99, as the change hasn't been documented in their changelog.

I have rolled back to nushell v.0.98.0 for now

Facing the very same issue, closing the one i had opened here as i didn't realized this is an ongoing issue since over a month

I ran into the same issue, I managed to solve it by appending the following at top of the generated file

$env.config = ($env | default {} config).config
$env.config = ($env.config | default {} hooks)
$env.config = ($env.config | update hooks ($env.config.hooks | default {} env_change))
$env.config = ($env.config | update hooks.env_change ($env.config.hooks.env_change | default [] PWD))

This will add the default PWD if it does not exist in env_change, I think adding this to https://github.com/jdx/mise/blob/main/src/shell/nushell.rs should solve the issue but I'm not sure since I'm using nixos to setup mise and nushell

I'm using nixos with home-manager for this, so I'm using the following code

{ config, pkgs, ... }:

let
  miseCmd = "${config.home.profileDirectory}/bin/mise";
in
{
  # mise
  programs.mise.enable = true;
  programs.nushell = {
      extraEnv = ''
        let mise_cache = "${config.xdg.cacheHome}/mise"
        if not ($mise_cache | path exists) {
          mkdir $mise_cache
        }

        $env.config = ($env | default {} config).config
        $env.config = ($env.config | default {} hooks)
        $env.config = ($env.config | update hooks ($env.config.hooks | default {} env_change))
        $env.config = ($env.config | update hooks.env_change ($env.config.hooks.env_change | default [] PWD))

        ${miseCmd} activate nu | save --force ${config.xdg.cacheHome}/mise/mise.nu
      ''; 
      extraConfig = ''
        use ${config.xdg.cacheHome}/mise/mise.nu
      '';
    };
}

Oh i forgot to update here that the fix for this issue has already been merged in nushell. It will be available in the next release nushell/nushell#14341.
In the mean time, before setting any env_change hooks, simply add $env.config.hooks.env_change = {} to your config.
