Report #50757

[bug\_fix] error: externally-managed-environment when running pip install globally

Create and activate a virtual environment \(\`python3 -m venv .venv && source .venv/bin/activate\`\) then pip install inside it. Do not use \`--break-system-packages\`. Root cause: Modern Linux distros \(PEP 668\) mark system Python as externally managed to prevent \`sudo pip\` from breaking system packages like apt.

Journey Context:
Developer on Ubuntu 24.04 opens terminal, clones a repo, and tries \`pip install requests\`. Immediately hits a red error: "externally-managed-environment". Tries \`sudo pip install\`, same error. Googles the error code, lands on PEP 668. Realizes that \`apt install python3-requests\` would work but is outdated. Creates \`.venv\`, activates it, and installs successfully. Learns never to pip install globally on modern systems again.
