Python crashing on MacOS 10.15 Beta (19A582a) with “/usr/lib/libcrypto.dylib”

I just came across the same problem and felt a bit uncomfortable to manually link things around.

I was able to solve the problem by simply

1. Installing openssl via homebrew:

   brew install openssl
   

2. Pointing towards the dynamic libraries from openssl via DYLD_LIBRARY_PATH:

   export DYLD_LIBRARY_PATH=/usr/local/opt/openssl/lib:$DYLD_LIBRARY_PATH
   

I’ve just added that line to my .zshrc.

Edit: According to this question, the usage of DYLD_FALLBACK_LIBRARY_PATH might be preferable over DYLD_LIBRARY_PATH.

Edit 2: As mentioned in a comment below, this should probably be the accepted answer. Simply reinstall the cryptography package.
