Scapy won't install using pip3

[mac_devuser]

Hello, I'm developing a messaging app that I'm researching and I plan to use scapy to forge custom protocols in python using scapy, but I can't seem to start the installation for it. When using

pip3 install scapy-python3

The following error occurs in the terminal.

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.

I don't know what to do now.

Looks like you need to install the Homebrew package manager and then use that to install scapy

I have just tried ' pip3 install scapy-python3 ' on my imac and it installed with no error.

Have you tried 'sudo pip3 install scapy-python3' ?

Or maybe try using a virtual environment for the install

The problem was homebrew, I recently installed it and ran into this trouble, after removing it I was able to install scapy. homebrew doesn't like installing scripts outside of a venv so uninstalling it was the only solution.
