I’ve had this issue pop up time and time again, so I wanted to document it so that I won’t forget in the future. The error below occurs when executing
RUN npm install sinopia in a Dockerfile FROM centos:6.6 (no doubt this isn’t specific to Docker).

The error seems obvious at first glance; g++ is not installed. But adding that as one of the packages I install at the top of the Dockerfile had no effect whatsoever.
RUN yum upgrade -y && yum install -y g++ tar
I trawled loads of GitHub issues and StackOverflow pages with similar problems. Some indicated it was a Node 0.12 issue, so I tried 4.2.1, but the error persisted. Because the sinopia seems to install and run correctly despite the error I almost gave up on trying to fix it. But I just hate seeing those errors in my build… I had to crack it.
Then I stumbled this GitHub issue that gave me hope:
No, on Centos 7, there is no g++ package in repos. However, I’ve installed gcc-c++ and the problem is solved
RUN yum upgrade -y && yum install -y gcc-c++ tar
