Answer 1

This might be a duplicate of gem install nokogiri -v '1.6.8.1' fails ... latest accepted answer there was to do:

brew unlink xz; bundle install; brew link xz

Re-linking xz might not be necessary ... if for example you only have that dependency because of the_silver_searcher (which links directly against the non-symlinked library).

Answer 2

gem update --system
xcode-select --install
brew unlink xz
gem install nokogiri -v '1.6.8.1'
brew link xz

If the above steps fail to fix the issue, what has also worked for me is running brew doctor and cleaning up any unbrewed header files.

Answer 3

Similar to yuяi's answer and from Nokogiri's help:

brew unlink xz
gem install nokogiri
brew link xz

This worked for 1.7.0.1

Answer 4

For Middleman

gem install nokogiri -v '1.8.2' -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/include/libxml2/

Answer 5

The more simple solution is to execute:

xcode-select --install
gem install nokogiri

Update

For Mojave I'm using gem install nokogiri -v '1.6.6.2' -- --use-system-libraries

Answer 6

Try install libxml2 first with Homebrew.

brew install libxml2

Then if installing with bundle

bundle config build.nokogiri --use-system-libraries \
  --with-xml2-include=$(brew --prefix libxml2)/include/libxml2
bundle install

If installing directly with gem

gem install nokogiri -- --use-system-libraries \
  --with-xml2-include=$(brew --prefix libxml2)/include/libxml2
