Error installing npm grunt-libsass - gruntjs

Question

I'm trying to install grunt-libsass like this:
npm install grunt-libsass --save-dev
but I get this error:
npm WARN engine grunt-libsass#0.2.1: wanted: {"node":"0.10.27"} (current: {"node":"5.1.1","npm":"3.3.12"})

what does the error say and how to fix it?

Answer 1

I recommend you to use grunt-sass instead of grunt-libsass because it is no longer maintained.
This task uses libsass which is a Sass compiler in C++.
