Answer 1

I had same issue while updating to xcode 10, I resolved it with following steps :

1. xcode-select --install
2. bundle install --deployment
3. gem install nokogiri

Answer 2

If you're using bundle:

brew install libxml2

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

I did everything in the other answers, but had to do one more thing:

1. Open Xcode
2. Click "Agree"
3. Wait a bit, close Xcode
4. Rejoice

Answer 4

Spencer's answer worked for me, but I also needed to use the -n parameter to overcome the permission issue documented here.

So in the end, the command that worked for me was:

gem install -n /usr/local/bin nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/libxml2 --use-system-libraries

Answer 5

This helped me fix this

• I reinstalled Xcode and directed xcode-select to its path

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

Answer 6

It may also be an issue with the anaconda version of some of the libs.

$ conda deactivate
$ gem uninstall nokogiri
$ gem install nokogiri
$ conda activate base

worked for me.
