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
After installing openssl I got the same problem. This answer didn't help me, but after manual linking of libcrypto.1.1.dylib and libssl.1.1.dylib everything start working. In my case it was:
ln -s /usr/local/opt/openssl/lib/libcrypto.1.1.dylib /usr/local/lib
ln -s /usr/local/opt/openssl/lib/libssl.1.1.dylib /usr/local/lib
