macOS catalina, Apache Benchmark (ab) not working, dyld library not loaded

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

Solution 1:

I found the solution on this post, https://github.com/kelaberetiv/TagUI/issues/635

brew uninstall openssl; brew uninstall openssl; 
brew install https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb
