Nah... I didn't manually do that. Look at the info for My hope openning the discussion was that I could get some insight into how formulas are installed so I could run a search on all the formulas I have installed to try to find the culprit |

Thanks for the thorough answer, @gromgit! A couple of things though... I'm not confusing pip packages with brew formulas. I made a point of NOT installing python via brew since I've had problems doing that before. And I think it's really weird to me that brew would change the default prefix of python3/pip3. (Ruby and gems via brew are also veeery messy btw) Anyways... look at the output below: 
I should have been more clear in the last message. Since I DID NOT install python via brew, nor set the pip3 prefix to use homebrew's bin folder, I imagine a formula I installed recently caused that mess. I don't know the brew architecture to figure out in a semi-automatic way (e.g. sourgraph structural search) so I'm asking for tips regarding which files to look for inside a formula, is there a "step" I should look into? All in all, I think I'm going to restore my installation of python/pip, simply move all the files in brew's bin leaving only brew and symlinks there and wait until something breaks. Unless you have a better idea :) |

Homebrew does NOT change the default prefix of a system or third-party Python installation. It doesn't even care about them. See the following references for how Homebrew deals with Python at the user level and the formula author level.
Just to be sure, what's the output of: ? You should also check your own startup files and other scripts, to see if you're setting any You might also want to mentally review your software installation actions on the dates of the files you tagged. For instance, how did you install
As far as I can tell, the only way a formula could do so is by ignoring everything in the Homebrew Python formula author's guidelines doc, and quietly using whatever |

UPDATE: I did a full cleanup of Homebrew packages and reinstalled everything. I'm using python installed via Homebrew and every binary I install via pip gets placed at @gromgit looks like this is the default behaviour |

oh... I must have read it in a hurry! For some reason, I was thinking of the prefix as the root folder of the installed python formula, not the homebrew prefix (which I think would be a better approach to avoid (rare) binary name conflicts) And hey, thank you so much for your patience. Really appreciated! |

TLDR; Always use There's a lot of chatter to wade through here, but the short answer for people experiencing this problem is that if you are To clean up the mess made by using # Zsh
