Ruby version - 2.3.7

Tried below approaches but shouldn't help

gem install nokogumbo -v '2.0.5' -- --use-system-libraries

gem install nokogumbo -v '2.0.5' -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk/usr/include/libxml2/

OK, it looks like the Nokogiri installation is in a bad state. Can you please un-install all versions of Nokogiri and then try gem install nokogumbo again?

[erajanraja24]

@flavorjones Thank you so much, uninstalling all versions of nokogiri and installing it again fixed the issue. Here's the command if someone having the same issue

gem uninstall nokogiri Install the version you need gem install nokogiri --version 1.10.10

check the version is displayed properly nokogiri -v
