MacOS – Stop installing python for each package by brew

homebrewmacospython

I have installed python on Mac by Anaconda. Here is the path :

/Users/USERNAME/anaconda3/bin/python
/usr/bin/python

But when I want to install any package that need python, it installs it separately. For instance, I wanted to install the gdb (GNU Debugger) via Homebrew, but it said that python is one of the requirements and then it installed it again.

How can I stop downloading and installing python for every package?

The nice thing about homebrew is it only installs dependencies needed to build the packages and also that you don’t have to choose just one version of a tool.

Why not let brew install what it needs, but control your path so that you’re running Anaconda from the python you prefer?

Also, brew has a cask install of anaconda as well, so that might be an easier path to harmony if you can’t get away from the homebrew installs for tools.

This is normal. System binaries are located in /usr/bin and other such directories that need to be in your path so that you can run them without needing to type the entire path in your shell.

Homebrew and other such package managers tell you to add the path to the folder for their own binaries so that they can also be run without typing the entire path. This folder should be added to the list of paths so that both the original binaries and the new binaries can be run in the same way.

FWIW I have plenty of paths in my $PATH:

/Users/grgarside/.autojump/bin:/Users/grgarside/.autojump/bin:/Users/grgarside/.rvm/gems/ru
by-2.0.0-p247/bin:/Users/grgarside/.rvm/gems/ruby-2.0.0-p247@global/bin:/Users/grgarside/.r
vm/rubies/ruby-2.0.0-p247/bin:/Users/grgarside/.rvm/bin:/usr/local/bin:/usr/local/sbin:/usr
/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sb
in:/sbin:/opt/X11/bin:/Users/grgarside/.rvm/bin
