# Python 3 (PEP 668)
|
||
|
||
|
||
|
||
```bash
|
||
$ brew install python@3.12
|
||
```
|
||
|
||
|
||
|
||
|
||
|
||
```bash
|
||
❯ python3.12 -m pip install --upgrade pip
|
||
error: 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 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.conf file. The latter
|
||
will permanently disable this error.
|
||
|
||
If you disable this error, we STRONGLY recommend that you additionally
|
||
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 more about this behavior 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 for the detailed specification.
