Error running gulp sass

Hi everyone!

I've just fixed problems with libsass or node-sass with this command:

$ sudo rm -rf node_modules/ && cat package.json | sed -i.bak 's/"gulp-sass": "^X.X.X"/"gulp-sass": "^2.0.4"/g' package.json && npm install && ionic lib update

Where X is the version of gulp-sass in your package.json

Explanation:

Remove the old files in node_modules. I'm not sure is necessary to use 'sudo' (in my case, yes).

$ sudo rm -rf node_modules/

Search and replace inside package.json updating gulp-sass version to ^2.0.4. It also creates a backup (package.json.bak),

$ cat package.json | sed -i.bak 's/"gulp-sass": "^X.X.X"/"gulp-sass": "^2.0.4"/g' package.json

Reinstall dependencies

$ npm install

Update the ionic lib in the project

ionic lib update

If you have any further problems be sure I try can help you...

Bye
