Python venv in ~/.local
Problem statement
lex@exi ~ % pip3 install glances
error: externally-managed-environment
× This environment is externally managed
╰─> 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.
Resolution
Install python support for virtual environment:
sudo apt install python3.11-venv
Create .local
:
python3 -m venv ~/.local --system-site-packages
Install glances
into .local
venv:
~/.local/bin/pip install glances
After the path is extended in .zshenv
as:
export PATH=$HOME/.local/bin:$PATH
Then:
alex@exi ~ % which glances
/home/alex/.local/bin/glances
