Uninitialized constant GraphViz (NameError)

[Yves Bouckaert]

Hi there,

I'm trying to use ruby-graphviz to generate a visual dependency graph with
 

$ bundle viz

But i'm getting this:

uninitialized constant GraphViz (NameError)

I wondering if was an installation problem but through i ran:

$ echo "digraph G {Hello->World}" | dot -Tpng >hello.png

 
And it works fine.

This is the content of my Gemfile.lock:

Did you `gem install ruby-graphviz` or `gem install graphviz`? `ruby-graphviz` is this gem's name, even though you `require "graphviz"`.
