Cannot install node-sass npm module - node.js

Question

I'm attempting to install the npm module "node-sass" on my Ubuntu 14.04 distro.
When I run
node -v
I get
v0.10.32
However, when attempting to install node-sass and harp with this command:
sudo npm install -g harp
I get the following error:
child_process: customFds option is deprecated, use stdio instead.

Note that the error states that my node version is still v0.13.0-pre even though I switched to 0.10.32 with nvm.

Question is 3 years old, yet I have recently encountered same problem on osx trying to install harp and found no solution elsewhere.
After several attempts managed to solve the problem with --unsafe-perm modifier, like follow:
sudo npm install --global --unsafe-perm harp
Install went successful and everything works, hope that helps :)
