### Fix [dyld: Library not loaded: /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib] error after upgrading openssl on OSX

On the weekend I played around with small data-sciency stuff on my laptop. It was just a small project, and I need to install something on my machine, it requires me to run a command to update my homebrew. But I accidentally run brew upgrade instead of brew update. That prior command turns out upgrade all of the homebrew formula and packages installed on my laptop to the latest version.
