A solution to g++ command not found an error while installing nodejs packages.

I was installing Browsertime on CentOS 7 and encountered this error.

Well, this could happen with any package which uses g++ library. To fix this error, all you got to do is install development tools with yum as below command.

yum groupinstall 'Development Tools'

Try to install what you were installing. It worked for me, and I hope for you too.
