Issues with installing nokogiri

I was trying to install nokogiri and it was keeps failing with the message below.

gitlab|category-search-dropdown ⇒ gem install nokogiri -v '1.6.8'
Building native extensions.  This could take a while...
ERROR:  Error installing nokogiri:
    ERROR: Failed to build gem native extension.

I could only fix it by running the command below.

gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2/

In somehow the command above didn't work for me until I quit iTerm and start new shell.

Perhaps this is the issue?

The key point here:

Then you are probably missing the right developer tools. This is a really easy fix:

brew unlink gcc-4.2      # you might not need this step
gem uninstall nokogiri
xcode-select --install
gem install nokogiri

I believe --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2/ part did the trick.

@fatihacet Yes, but the problem with that approach is that every time nokogiri is upgraded, you will have to remember that magic incantation. I think I fixed it with the notes above. If they also work for you, please add this to the README.md.

It seems it's working. I will update the GDK README.

Status changed to closed

I accidentally pushed to master of GDK. https://gitlab.com/gitlab-org/gitlab-development-kit/commit/39d41b4fe6163e6e7749db35d9daa29f1f3f63a0

No worries; I made master a protected branch on this project. It wasn't set before.

Thanks @fatihacet @stanhu
