well yeah you need ruby to run a ruby gem?



I had ruby - I was missing the ruby-dev header files.

My original complaint though is that people are using "gem install" as the sole documentation for installing a general purpose command-line tool. I'd rather not even know it's written in Ruby (I just want to install it and use it) - instead, I need deep Ruby knowledge just to get the thing running.

I hate that it's using gem for install, too.

-----


If knowing how to type "yum install ruby-devel" qualifies as "deep Ruby knowledge", I must be some kind of god.

-----


More importantly, apparently in this case you need the ruby dev package to install the relevant gem from source.

-----


Smug reply implies that gems are only for people who develop in ruby.

-----


Smug reply says that gems require things to work, and given that they're usually dependent on some version of ruby then the smug reply is usually right.

-----


It's not generally obvious to non-developer end users that they will (sometimes) need to install the -dev package on their OS. Would be nice if it were. I'm mostly taking issue with the unfriendliness of the comment.

Gems ARE only for people who develop in ruby.

-----


Did you happen to read the article? It has nothing to do with developing in ruby.

-----


There is no article attached to this post. Just the homepage of a small piece of software targeted at developers who are familiar with installing gems.

If YOU read the content that was linked, you'd see there is a very long README targeted at people who aren't Ruby developers.
