or: externally-managed-environment
× This environment is externally managed
╰─> To install Python packages system-wide, try brew install
xyz, where xyz is the package
you are trying to
install.
If
you wish to install a Python library that isn't in Homebrew,
use a virtual environment:
python3 -m venv path/to/venv
source path/to/venv/bin/activate
python3 -m pip install xyz
If
you wish to install a Python application that isn't in Homebrew,
it may be easiest to use 'pipx install xyz', which will manage a
virtual environment f
or you.
You can install pipx w
ith
brew install pipx
You may rest
ore the old behavi
or of pip by passing
the '--break-system-packages' flag to pip,
or by adding
'break-system-packages = true' to
your pip.conf file. The latter
will permanently disable this err
or.
If
you disable this err
or, we STRONGLY recommend that
you add
itionally
pass the '--user' flag to pip,
or set 'user = true' in
your pip.conf
file. Failure to do this can result in a broken Homebrew installation.
Read m
ore about this behavi
or here: <https://peps.python.
org/pep-0668/>
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 f
or the detailed specification.
