Make sure that `gem install nokogiri -v '1.6.6.4'` succeeds before bundling. ERROR

Question

I try to Create Rails Apps but i keep getting this error with nokigiri. Did anyone had this issue before ?

Make sure that `gem install nokogiri -v '1.6.6.4'` succeeds before bundling.
         run  bundle exec spring binstub --all

i tried to install the gem but still no improvement. Here's a screenshot:

Answer 1

Try:

xcode-select --install

Also, Nokogiri requires libiconv , so you may need to install it and install the gem again with options --with-iconv-lib and/or --with-iconv-include specified.
