Can't install Ionic node-sass problem

I’m trying to install Ionic in manjaro but it is not possible

I’m using nvm with node v4.0.0 (Node 5 does not work at the moment!) and npm 3.8.0 but when I run sudo npm install -g ionic I get this error

$ sudo npm install -g ionic
/home/xx/.nvm/versions/node/v4.0.0/bin/ionic -> /home/xx/.nvm/versions/node/v4.0.0/lib/node_modules/ionic/bin/ionic

> node-sass@3.4.2 install /home/xx/.nvm/versions/node/v4.0.0/lib/node_modules/ionic/node_modules/node-sass
> node scripts/install.js

module.js:338
    throw err;
          ^

could you please help me to solve this?

Thanks :slight_smile:

I got the solution from stack overflow

If you are using nvm you should install the packages without sudo and everything works.
