On Debian 12 Bookworm, Ubuntu 24.04 Noble Numbat, and macOS 14+ installs, when I try running
pip3 install [something]
(whether that's Ansible or some other Python tool), I get the following error message:
error: externally-managed-environment
à This environment is externally managed
â°â> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.
If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.
If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.
See /usr/share/doc/python3.11/README.venv for more information.
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
The error message says you can pass in the flag
--break-system-packages
but that sounds terrifying. I just want pip to stop nagging me, but let me manage my system dependencies like I have for many years.
I think some Python developers really want people like me to use virtual environments , but that's way too much effort when I don't really care to do that, thankyouverymuch. If you want to use
venv
more power to you. I just like getting stuff done on my little servers.
The easiest solution is to delete the
EXTERNALLY-MANAGED
file in your system Python installation:
sudo rm -rf /usr/lib/python*/EXTERNALLY-MANAGED
If using Ansible, you can add this task to your playbook prior to running any
pip
tasks:
- name: Ignore PEP 668 because it's silly.
ansible.builtin.file:
path: /usr/lib/python3.11/EXTERNALLY-MANAGED
state: absent
Ansible also has a new
break_system_packages
option for the pip module, so if you just need to do it once:
- name: Install package via pip.
ansible.builtin.pip:
name: "package_name_here"
state: present
break_system_packages: true
become: true
Note that the
python3.11
version number should match whatever you have installedâit was 3.11 at the time of this blog post's writing.
- For Ubuntu 24.04, the version is
python3.12, and for 26.04,python3.13 - For macOS, use
find /opt/homebrew -name EXTERNALLY-MANAGEDto find the location (orfind /usr/local -name EXTERNALLY-MANAGEDon Intel Macs)
See this answer on Stack Overflow for more. Another interesting option is to install and use pipx , which does the grunt work of managing the
venv
s for you.
