Question

I've been working on one error for about an hour. I've been development an app in Nix on REPLIT. But no matter what I do this error comes while installing packages with with Python Pip:

Firstly, this came up whilst installing any packages... But I realized it also comes up in attempt to update Pip.

ERROR: Could not install packages due to an OSError: [Errno 13] Permission denied: '/nix/store/8d3695w7vasap3kkcn3yk731v4iw2kcv-python3.8-pip-21.1.3/bin/pip' Consider using the `--user` option or check the permissions.

My replit.nix:

{ pkgs }: {
    deps = [
        pkgs.cowsay
        pkgs.python38Full
        pkgs.python38Packages.pip
    ];
    env = {
      PYTHONBIN = "${pkgs.python38Full}/bin/python3.8";
      LANG = "en_US.UTF-8";
    };
}
