Brew doctor: dyld: Library not loaded & Error: No available formula for zlib

Question

When I brew doctor I get the following errors:

dyld: Library not loaded: /usr/lib/libltdl.7.dylib
  Referenced from: /usr/local/bin/php
  Reason         


        

Answer 1

In my case I had

dyld: Library not loaded: /usr/local/opt/python/Frameworks/Python.framework/Versions/3.7/Python
  Referenced from: /usr/local/Cellar/macvim/8.2-162/MacVim.app/Contents/MacOS/Vim
  Reason: image not found

brew unlink python && brew link python and boom, fixed.
