Incorrect evaluation in directories with spaces in name

[ejb-11]

Describe the bug

I am new to this software and am testing it to see if it will work for me (I need to install Python libraries unavailable in nixpkgs and I understand it is better practice to use virtual environments anyway). I was going absolutely insane trying to work out what was wrong for a while, but I managed to figure it out after removing some red herrings that the error trace incorrectly returned as having broken.

As the title implies, running devenv shell does not work correctly in a directory with spaces in its name, but works fine in one without.

To reproduce

Run devenv init
Use this simple devenv.nix:

#devenv.nix
{
  pkgs,
  lib,
  config,
  inputs,
  ...
}:

{
  languages.python = {
    enable = true;
    venv.enable = true;
    venv.requirements = lib.readFile ./requirement.txt;
  };

  enterShell = ''
    python -c "import control as ct" && echo "No errors!"
  '';
  cachix.enable = false;
}

Use this requirement.txt:

#requirement.txt
control==0.10.0

Then run devenv shell.

In a folder with no spaces in the name, it will run normally and return
No errors!
But in one with spaces in its name, it will return with an error (in this example, the folder is /home/ejb/Documents/Uni/Masters/Control and Estimation Theory, and each word is erroneously evaluated as a function):

Duplicate of #1107.

Why is this issue closed as completed when the other issue is stale and abandoned? Is there a timeline for getting this problem fixed, or should I find some other software like how the other person had to?

[sandydoo]

We already have a tracking issue for this.
It's not stale or abandoned. We don't have an immediate fix for this because the issue is with Nix, not devenv.
