Description
- I believe this to be a bug, not a question about using Jekyll.
- I updated to the latest Jekyll (or) if on GitHub Pages to the latest
github-pages - I am on (or have tested on) Debian/Ubuntu GNU/Linux
- I was trying to install.
My Reproduction Steps
I followed the basic installation instructions to the letter, but as administrator, on the latest version of Ubuntu (16.04).
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install ruby
sudo gem update
sudo gem install jekyll
Here's where things went wrong during sudo gem install jekyll:
Building native extensions. This could take a while...
ERROR: Error installing jekyll:

It was because gcc was not installed. I've also found that some people needed make. Please add that to the installation requirements. I also installed ruby-dev to be sure. Thanks. :)
