Answer 1

I updated node.js to the latest version using :

# Using Ubuntu
curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs

for my Ubuntu machine, as shown here.

After that i updated NPM using :

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

As shown here.

Now the gulp-autoprefixer start working but i got an error from gulp-sass. I updated it using this instruction :

1. Delete your node_modules folder
2. Remove gulp-sass from your package.json file
3. Remove node-sass from your package.json file (if you have it in there)
4. Run npm install gulp-sass --save-dev
5. Update your Gulp task as required

Found here.Now i have "gulp-sass": "^2.0.4" and this fixed all my problems.

Thanks for advice and help.
