Failure: gem install rbczmq due to autogen error

Question

I am trying to add IRuby kernel into my Jupyter so that I can write notes on Ruby, as I just started learning to solve problems in Ruby. On the IRuby doc, I am supposed to do the following commands:

gem install rbczmq
gem install iruby

However, when I do gem install rbczmq I get permission denied. When I do sudo gem install rbczmq, I get the following:

Building native extensions.  This could take a while...
ERROR:  Error installing rbczmq:
    ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary

need configuration options.

extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.3.0/gems/rbczmq-1.7.9     for inspection.
Results logged to /var/lib/gems/2.3.0/extensions/x86_64-    linux/2.3.0/rbczmq-1.7.9/gem_make.out

I would like to know how I can fix this problem and install IRuby to my Jupyter? Thank you!

Answer 1

I had the same problem, after hours of trial and error, I finally manage to install it.

I used sudo apt-get install libtool-bin and then sudo gem install rbczmq

I hope this helps
