Error Installing Jekyll - Native Extension Build

If you installed XCode and command line tools are still missing go to Terminal and

xcode-select --install

it will prompt you to install these tools. After that just follow SrBlanco´s answer. That solved the problem for me.

Good luck.

Ubuntu

1. sudo apt-get install ruby-dev
2. gem install jekyll

Your problem is that either you system doesn't know where make is located at or you don't have it installed. The easiest way to fix this (and probably other issues you'll run into trying to get a ruby system up and running) is to install xcode.

You can get it at http://itunes.apple.com/us/app/xcode/id497799835?ls=1&mt=12 for lion. Or it came on a CD with your computer for earlier versions.

If you're using Lion, please see comments below for a link to how to install developer tools on Lion.

I had the same error on Ubuntu and this helped me sort it out.

You must have ruby-dev installed

apt-get install ruby-dev
