gem install sass: http://sass-lang.com/install

Hi @petecoop !
I've already installed ruby gem before using this generator.
This is the reason why I created this issue.

[petecoop]

Can you run sass?

[eko24]

Yes I can:

[petecoop]

Is it >= 3.4? Also check: https://github.com/sindresorhus/gulp-ruby-sass

[eko24]

Yes it is

In my PC：

ruby 2.3.3p222 (2016-11-21 revision 56859) [x64-mingw32]

Sass 3.5.5 (Bleeding Edge)
node v8.9.3
gulp CLI version 3.9.1

someone who can help me

[petecoop]

I'd really recommend using node sass instead of ruby sass, it has far less issues!

[kakudesu]

in fact,this problem appears in the development environment of node gulp-sass.

[petecoop]

can you share your package.json?

[kakudesu]

in fact,gulp-ruby-sass has installed,but it doesn't work

[iamalisajid]

still having this issue :(

[iamalisajid]

What i found, that it was an issue with node version. Taking it back to node 8.1.4 solves it for me.
