error: externally-managed-envir
onment
×
This envir
onment
is externally managed
╰─> To install Pyth
on packages system-wide, try brew install
xyz, where xyz
is the package you are trying to
install.
If you w
ish to install a Pyth
on library that
isn't in Homebrew,
use a virtual envir
onment:
pyth
on3 -m venv path/to/venv
source path/to/venv/bin/activate
pyth
on3 -m pip install xyz
If you w
ish to install a Pyth
on applicati
on that
isn't in Homebrew,
it may be easiest to use 'pipx install xyz', which will manage a
virtual envir
onment
for you. You can install pipx with
brew install pipx
You may restore
the old behavior of pip by passing
the '--break-system-packages' flag to pip, or by adding
'break-system-packages = true' to your pip.c
onf file.
The latter
will permanently d
isable
this error.
If you d
isable
this error, we STR
ONGLY recommend that you additi
onally
pass
the '--user' flag to pip, or set 'user = true' in your pip.c
onf
file. Failure to do
this can result in a broken Homebrew installati
on.
Read more about
this behavior here: <https://peps.pyth
on.org/pep-0668/>
note: If you believe
this is a m
istake, please c
ontact your Pyth
on installati
on or OS d
istributi
on provider. You can override
this, at
the r
isk of breaking your Pyth
on installati
on or OS, by passing --break-system-packages.
hint: See PEP 668
for the detailed specificati
on.
