If you could provide a snippet to reproduce I could help debug.

This seems to work for me, maybe it will help unblock you:

```console
$ mkdir /tmp/foo;
$ cd /foo;
$ flox init -t project -i;
$ flox init -t package-simple -n foo;

# Manually create an env for this package
$ cat <<'EOF' > ./pkgs/foo/flox.nix
{
    environmentVariables.envName = baseNameOf ./.;
  shell.hook = ''
    echo "Welcome to the '$envName' environment" >&2;
  '';
}
EOF

# Re-render the changed environment
$ EDITOR=cat flox edit '.#foo';
$ bash -c ". <( flox activate -e '.#foo'; );" 2>/dev/null;
Welcome to the 'foo' environment

# Add a package
$ flox install -e '.#foo' hello;
Installed 'hello' package(s) into '.#foo' environment.

# Rename the env
$ mv ./pkgs/foo ./pkgs/bar;
$ git add ./pkgs/bar;

# Render the new env
$ EDITOR=cat flox edit '.#bar';
$ bash -c ". <( flox activate -e '.#bar'; );" 2>/dev/null;
Welcome to the 'bar' environment

```

The critical piece here is the “reload”/“re-render”.

You may also find this `direnv` snippet useful, which makes it so you don’t need to manually re-render:

```shell
# Reload any changes to `flox.nix' file.
# Capture output and check for errors.
_msg="$( EDITOR=cat flox edit -e '.#default' 2>&1; )";
case "$_msg" in
  *ERROR*|*error*)
    echo "Failed to update flox environment:" >&2;
    echo "$_msg" >&2;
    exit 1;
  ;;
  *)
    # Activate `flox' env.
    . <( flox activate -e '.#default'; );
  ;;
esac

```
