    Uninstall current npm and install lower versions, it is a common error if version didn't match, downgrading node/npm will mostly fix this kind of issues

    npm install -g npm@4.6.1

    Got the same problem (node v10.3.0, ionic 3.13.0). This worked :

    • Delete package-lock.json,
    • Delete node_modules folder,
    • Run npm install again.

    The following steps worked for me

    npm install -g node-sass@4.5.0 --unsafe-perm=true --allow-root
    
    npm cache clean
    
    
    npm install

    The minimum version of node-sass that supports Node 8 is 4.5.3. You'll need to upgrade your node-sass or downgrade your Node version. Ionic may also have separate issues since it isn't a tested platform with node-sass.
