Deployment to EBS - Helo debugging ERROR: CMake is required to build Rugged.

Being trying to deploy my rails app using EBS. I kepp getting the following error.

I've tried updating and installing rugged. But the problem seems to be cmake on EBS. CMake is an extensible the depends from the Rugged gem.

Any ideas on how to debug this?

Im using rails 5.0.1 and Ruby 2.3.1.

  To see why this extension failed to compile, please check the mkmf.log which can be found here:

Unless I'm just reading it wrong, the error is just that, you don't have cmake installed...

ERROR: CMake is required to build Rugged.

sudo apt-get install cmake

If you do have cmake, check the end of your error log, it says:

To see why this extension failed to compile, please check the mkmf.log which can be found here:
/var/app/ondeck/vendor/bundle/extensions/x86_64-linux/2.3.0-static/rugged-0.25.0b10/mkmf.log

So you can check the log there to see if it gives any additional details

Thanks Jacob! I apperently did have cmake installed on my local machine but not in AWS.

Sweet, I'm glad that really was the issue!

I've done that countless times, imagemagick gets me everytime!!
