Description of issue

I have installed Python 3.12.3 using Homebrew in MacOs. I am trying now to install the module requests, using brew install python-requests, and I got the message: Warning: python-requests has been deprecated because it does not meet homebrew/core's requirements for Python library formulae!

I am confused if the module is not available from Homebrew? when I run import requests in Phyton env, I got the error that the module is not found.

Any help would be appreciated.
Thanks

You should probably install it with pip, not with Homebrew since it's going away soon

[chucker]

But, FWIW, pip says to use Homebrew…

❯ pip3 uninstall requests
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.

(What I ended up doing was pip3 install --break-system-packages requests, but that's discouraged…)

[SMillerDev]

Pip says you can try to use Homebrew. Sometimes it'll work, sometimes it won't. Using virtual environments will always work.

[ChristopherSchultz]

    python3 -m venv path/to/venv
    source path/to/venv/bin/activate
    python3 -m pip install xyz

Following those instructions:

$ python3 -m pip install requests
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.

Suggestions?

I'm beginning to think that using Python for anything serious isn't tenable in the long-term.

[ChristopherSchultz]

Oh, and adding --break-system-packages to any command line I tried results in an "unrecognized argument" error.

[in-ch]

It can be solved as follows.

mkdir ~/.venv 

python3 -m venv ~/.venv 

source ~/.venv/bin/activate 

python3 -m pip install requests

One inconvenience is that you'll need to reactivate the virtual environment each time you restart the terminal:

source ~/.venv/bin/activate
