I just got this error trying to install ab on my Catalina macOS:
brew install homebrew/apache/ab Error: homebrew/apache was deprecated. This tap is now empty and all its contents were either deleted or migrated.
not sure what to do...
Actually what I want to do is to make ab work: I found out that ab (apache benchmark tool) is already installed on macOS, but it doesnt' work:
$ab dyld: Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib Referenced from: /usr/local/bin/ab Reason: image not found Abort trap: 6
