I managed to fix (?) it by adding require 'resolv-replace' to lib/jekyll-postcss.rb

I managed to fix (?) it by adding require 'resolv-replace' to lib/jekyll-postcss.rb

where did you add this?

[benoliver999]

Next to the other require statements - maybe line 6?

sorry dude i really don't understand anything. English is not my native language, maybe that's why

[benoliver999]

No problem.

On my computer I opened the file called lib/jekyll-postcss.rb

(For me on my computer this was in ~/.gems but I am on Linux)

Below line 5 I added a new line and wrote:

require 'resolv-replace' to lib/jekyll-postcss.rb

Then I saved the file.

It's not perfect because I edited the package itself, but until we can find the problem this worked for me.
