Answer 1

Github Answer

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

bundle install

Answer 2

I had a similar issue with 1.6.7.2 when bundle installing on codeship with ruby 2.3.

What worked for me was adding:

bundle config build.nokogiri --use-system-libraries

before

bundle install

Answer 3

Run these commands:

gem uninstall nokogiri
xcode-select --install
gem install nokogiri

source: http://www.nokogiri.org/tutorials/installing_nokogiri.html#mac_os_x

sometimes mac updates can break xcode CLI so reinstalling can fix the issue: https://github.com/sparklemotion/nokogiri/issues/1445

Answer 4

Try this

sudo apt-get install build-essential patch ruby-dev zlib1g-dev liblzma-dev

And then install Nokogiri

sudo gem install nokogiri

Answer 5

If nothing above works, Try deleting Gemfile.lock, and do reinstalling of gems.

Answer 6

Deleting nokogiri in rbenv gem folder and reinstalling solved it for me.
