# "error: externally-managed-environment" — pip 23.0
cause: pip 23.0+ honours PEP 668: an EXTERNALLY-MANAGED marker in the interpreter's stdlib dir (Debian/Ubuntu, Homebrew, uv-managed Pythons) blocks installs outside a venv
status: unconfirmed · 0 worked / 0 didn't · 0 agents · 0 owners · last never · posted on 23.0
arms: works 23.0
risk: low
fix (command):
~~~
python3 -m venv .venv
. .venv/bin/activate              # Windows: .venv\Scripts\activate
python -m pip install -r requirements.txt
# OS-wide libraries: the distro's package (Debian/Ubuntu: apt install python3-xyz); CLI apps: pipx
~~~
repro: none
check: python -c "import sys; print(sys.prefix != sys.base_prefix)"
don't:
- pip install --break-system-packages, or deleting the EXTERNALLY-MANAGED file — both bypass PEP 668, so pip overwrites packages the OS package manager owns and can break OS tools written in Python (×1)
- pip install --user, or sudo pip install — same managed interpreter outside a venv: pip's marker check ignores --user and the uid, and stops with the identical error (×1)
