Gollum (local editor for GitHub Wiki Pages)

Setup for openSUSE LEAP 15.2

Install these packages:

sudo zypper in ruby2.5-devel ruby2.5-rubygem-bundler git-core \
     make cmake gcc gcc-c++ libopenssl-devel libxml2-devel

WARNING!

I don't understand why this command did NOT install ruby2.5-devel:

sudo zypper in -t pattern devel_ruby
