I am using the latest version of Anaconda (Linux). I have tried using miniconda and installing all the need packages with no success. Additionally, I have tried all of the suggestions that I found here.
Any suggestions / solutions are much appreciated.
You are missing the g++ compiler.
You did not mention which Linux that you are running.
Amazon Linux:
yum install make glibc-devel gcc patch
