From 3a5443375f1a3c4de916f8da467e13944504303c Mon Sep 17 00:00:00 2001 From: solfx Date: Sun, 19 Apr 2026 08:33:49 -0700 Subject: [PATCH] Drop requests dep and handle PEP 668 environments - Replace `requests` with stdlib `urllib.request` so the script runs with zero third-party deps on Linux / macOS, avoiding the PEP 668 "externally-managed-environment" failure on Homebrew Python 3.11+ and recent Debian/Ubuntu. - Make remaining installs (Windows-only `colorama` / `tzdata`) retry with `--user` and `--break-system-packages --user`, and degrade silently instead of exiting when install still fails.
