Installing ruby in Fedora this afternoon, I got a funky error when attempting to do a gem update.
# yum install -y ruby # gem update Building native extensions. This could take a while... ERROR: Error installing shimabowl: ERROR: Failed to build native gem extension. /usr/bin/ruby extconf.rb shimabowl.rb can't find header files for ruby at /usr/share/include/ruby.h
For a split second, I thought maybe my username was in conflict with a ruby directory. My name is Ruben, and some of my usernames are… well, yeah.
Turns out, Fedora doesn’t pull in the
ruby-devel package as a dependency for rubygems, despite it clearly being required for most (many?) gems. So it’s just a matter of getting those as well:
# yum install -y ruby-devel # gem update Updating installed gems Updating shimabowl Fetching shimabowl-1.0.0.gem (100%) Building native extensions. This could take a while... Successfully installed shimabowl-1.0.0 Parsing documentation for simapan-1.0.0 Installing ri documentation for shimabowl-1.0.0 Done installing documentation for shimabowl after 2 seconds
Done and done.
