Impossible to install Nokogiri - OSX Mojave 10.14.2
Since the recent update (10.14.2) Nokogiri gem cannot be installed in my app.
When I run
bundle install , I get the following error:
./siteconf20190109-70456-1diyett.rb extconf.rb --use-system-libraries checking if the C compiler accepts -march=core2 -mtune=haswell -mssse3 -ftree-vectorize -fPIC -fPIE -fstack-protector-strong -O2 -pipe... yes checking if the C compiler accepts -Wno-error=unused-command-line-argument-hard-error-in-future... no Building nokogiri using system libraries.

I went to the nokigiri installation tutorial, but their solution does not work.
Do you have any idea to solve this problem?
libxml2 is missing. so you might have just missed installing that dependency.
That's a simple
brew install libxml2 to fix. 👍
I'm still on High Sierra for my main computer, but let me open up Macbook which I upgraded.
My guess is that it's simply looking in the wrong folder still.
Did you try this line I had in the guide?
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
I noticed that the Nokogiri docs had a slightly different one.
Yes, I tried your line from the guide.
then I ran
gem install nokogiri
I got a another error:
RROR: Error installing nokogiri: ERROR: Failed to build gem native extension. current directory: /Users/charbell/.rvm/gems/ruby-2.4.4/gems/nokogiri-1.10.0/ext/nokogiri /Users/charbell/.rvm/rubies/ruby-2.4.4/bin/ruby -I /Users/charlesbellorini/.rvm/rubies/ruby-2.4.4/lib/ruby/site_ruby/2.4.0 -r ./siteconf20190109-76119-6rjiq6.rb extconf.rb checking if the C compiler accepts -march=core2 -mtune=haswell -mssse3 -ftree-vectorize -fPIC -fPIE -fstack-protector-strong -O2 -pipe... yes checking if the C compiler accepts -Wno-error=unused-command-line-argument-hard-error-in-future... no Building nokogiri using packaged libraries.

Thank you very much for your help.
Getting closer it sounds like.
Try this and see if that helps.
gem install nokogiri -- --use-system-libraries --with-iconv-dir=$(brew --prefix libiconv) --with-xml2-include=$(brew --prefix libxml2)/include/libxml2
Alternatively, this one does the seame thing but doesn't use the libraries from homebrew in case the above fails:
gem install nokogiri -- --use-system-libraries=true --with-xml2-include="$(xcrun --show-sdk-path)"/usr/include/libxml2
According to Nokogiri's issues, they might have a fix coming out at some point soon so you won't have to do these workarounds. https://github.com/sparklemotion/nokogiri/pull/1851
Both of them does not work. it comes with the same error :
libxml2 is missing. Please locate mkmf.log to investigate how it is failing.
brew install libxml2
bundle config build.nokogiri --use-system-libraries --with-xml2-include=/usr/include/libxml2/
I have this in my notes and I got the answer on Stackoverflow.
