undefined method `create_element' for #<Nokogiri::HTML5::DocumentFragment:0x0055a68d62d9a8>

[jherdman]

When using Nokogiri 1.9.1 and Nokogumbo 2.0.1, the following error comes out of some of our templates:

      NoMethodError:
        undefined method `create_element' for #<Nokogiri::HTML5::DocumentFragment:0x00564bbaaf74c0>
        Did you mean?  create_external_subset

Looking a little into the stack trace we see:

from /home/vagrant/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/premailer-1.11.1/lib/premailer/adapter/nokogumbo.rb:157:in `write_unmergable_css_rules'

Hopefully more data to come...

OK, I've found the bug. I'll be sending up a PR shortly.

[utkarsh2102]

@jherdman, any update?

[jherdman]

@utkarsh2102 I tried fixing this but failed pretty hard. Ultimately we bailed on this project in favour of roadie.

[utkarsh2102]

Ah.
@jherdman we'd need this gem for premailer-rails, which is needed by gitlab.
And there are multiple test failures.
D'you have time to look into them? :(

[jherdman]

Alas, I'm merely a humble dev in the same boat as you. I have no authority on this project. Best of luck!

@utkarsh2102 @jherdman we just did some sprucing up of the master branch, including bumping the versions of all of our dependencies. Would either of you mind pointing your projects at premailer:master to see if this issue is now resolved?

[jherdman]

Hey @meowsus !

I sadly won't be able to help. We bailed on Premailer for Roadie. Best of luck!

[meowsus]

@jherdman I figured as much, but thanks for your response!
