Error on new version 2.3.0

[lughino]

Hi,
I get this error when I launch the task:

/var/www/test/node_modules/node-sass/lib/index.js:180
  options.includePaths = (options.includePaths || []).join(path.delimiter);
                                                      ^

with gulp-sass version 2.2.0 there is no problem.

Thanks for report @lughino. I believe I have a fix in #474. Waiting on confirmation from the person who removed this code.

A work around for now is setting the includePaths: [] option.

[bigjollygiant14]

Same issue for me. @extend and @import aren't working anymore. On demo day too :(. Going to try the include paths for now.

[timhettler]

In previous versions includePaths accepted a String

[xzyfer]

I've released v2.3.1 which restores the old behaviour.
