I have no experience with Ruby. When I try to do gem install nokogiri on MacOS I am getting.
Building native extensions. This could take a while...

Did you try?
gem update --system
xcode-select --install
The following should fix your issue:
sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install
sudo xcodebuild -license accept
open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
I'm currently having this problem when i try to install Rubocop(I can't install nokigiri either):

I've tried others solutions, but none worked.
Anyone knows why i'm getting this error ?
Thx
You need to install development headers for ruby 2.5, you don't have a development environment installed:
sudo apt-get install ruby2.5-dev
May also be called -devel depending on your packaging system.
I'm trying to install Jekyll using:

You have to install the Ruby DevKit. Depending on your installation of Ruby, you have to select the correct way to install it.
When i run:
sudo gem install yajl-ruby
I see errors:
Building native extensions. This could take a while...

I have installed yum install ruby rubygems ruby-devel, but still have this problem.
Try:
$ sudo ln -s /usr/bin/llvm-gcc /usr/bin/gcc-4.2
$ sudo gem install yajl-ruby
Good day
I have a Mac with OSX Yosemite
I'm trying to install the compass with the command:
sudo gem install compass
but I am getting the following error:

before attempting to install the package I updated the gem with the command
sudo gem update --system
and the update occurred without errors
You probably need to install the command line developer tools first.
xcode-select --install
Then try sudo gem install compass again
