bash
python3.11 -m pip install requestsNotes
Great when several minor versions are installed side-by-side.
bash
python -c "import sys; print(sys.executable)"Notes
Useful before installing packages so you know where they will land.
venv Workflows
Create venv and install packages
Typical Unix-like local development flow.
bashANYvenvbootstrapdevelopment
bash
python -m venv .venv && source .venv/bin/activate && python -m pip install --upgrade pipNotes
Creates an isolated environment, activates it, and upgrades pip inside it.
Install requirements into an active venv
Install project dependencies after activation.
bashANYvenvrequirementsinstall
bash
python -m pip install -r requirements.txtNotes
Once the venv is active, `python -m pip` targets that environment.
Install to user site packages
Install packages into the user site directory.
bashANYusersite-packagesinstall
bash
python -m pip install --user httpieNotes
Helpful when you cannot write to system site-packages. Avoid inside a venv.
Install despite externally managed environment
Override system package management protections when necessary.
bashANYsystem-pythonsafetyinstall
bash
python -m pip install --break-system-packages requestsNotes
Use cautiously. On many Linux distributions, using a venv is safer.
CI and Automation

Bootstrap common packaging tools in CI.

bash
python -m pip install --upgrade pip setuptools wheelNotes
A common setup step before building or installing packages in automation.
bash

Useful in CI systems or scripts where prompts would hang execution.
Disable version check
Skip pip’s self-update version check.
