Not able to install Nokogiri because of gcc on MacOS Catalina

I am trying to install nokogiri on my MacOS Catalina 10.15.1

gem install nokogiri

The error in the log file I see is as following

I have been googling and i have tried to install gcc via brew install gcc&& brew link gcc but that does not help. Here are the gcc version i have.

$which gcc
/usr/local/bin/gcc

$gcc -v
Using built-in specs.

gcc version 9.2.0 (GCC)

I have also tried the following which did not work.

1. gem install nokogiri -- --use-system-libraries
2. CC=llvm-gcc gem install nokogiri

I am out of all ideas and anything i am finding online does not seem to work, I will appreciate any tips here.
