“ERROR:root:code for hash md5 was not found” when using any hg mercurial commands

Question

When trying to use any hg Mercurial commands on the console, I keep getting this error. I installed Python using Homebrew and I am running Mac OS Catalina v. 1

Answer 1

The next solution worked for me on MacOS Catalina:

1. Unlink openssl

brew unlink openssl

2. Reinstall python 2.7 (removed from homebrew and can't be installed via brew install python@2)

brew tap-new /homebrew-python2
brew extract python@2 /homebrew-python2
brew reinstall /usr/local/Homebrew/Library/Taps//homebrew-python2/Formula/python@2.7.17.rbl
