Can you please help me resolve this? I am inexperienced and could not find any blog related to this.

Hi @am-root, sorry you're having problems. I'll try to help!

Summary: Please try apt remove ruby-nokogiri followed by apt autoremove to get rid of the Nokogiri debian package. After that it should work fine.

Explanation

This is the key error from the output you shared:

/usr/lib/ruby/vendor_ruby/nokogiri/xml/xpath/syntax_error.rb:4:in module:XML': XPath is not a class (TypeError)
/var/lib/gems/2.7.0/gems/nokogiri-1.12.5-x86_64-linux/lib/nokogiri/2.7/nokogiri.so:0: previous definition of XPath was here

I see that you have two different installations of Nokogiri:

I'm guessing the /usr/lib version is a debian package based on v1.11.1 or earlier -- which is beforeXPath was changed from a class to a module -- and the other version is something a different package manager has installed.

I don't recommend using debian packages for Ruby gems -- especially if you're using bundler or gem install for other gems -- because they tend to collilde in unpleasant ways like this.
