Invalid struct field type #<FFI::Type::Builtin:POINTER size=8 alignment=8> (TypeError)

[Vivien Richter]

I want to use @use so i need to use the Dart Sass implementation.

group :jekyll_plugins do
  gem "jekyll-sass-converter", github: "jekyll/jekyll-sass-converter"

My config.yml sass part:

sass:
  implementation    : sass-embedded # Compiler (Possible values: 'sassc' [default] for LibSass [DEPRECATED], 'sass-embedded' for Dart Sass [requires Ruby 2.6 or higher])
  style             : expanded # The style of the CSS-output (Possible values: 'expanded', 'nested', 'compact', or 'compressed').
  sass_dir          : _sass # A filesystem-path which should be searched for Sass partials.
  load_paths        : [] # An array of additional filesystem-paths which should be searched for Sass partials.
  line_comments     : true # Include the line number and filename of the source in the compiled CSS-file.
  sourcemap         : always # Controls when source maps shall be generated (Possible values: 'never', 'always' or 'development').

Interesting: If i set implementation : sassc, the issues not changes.

I used bundle install and bundle clean after every cahnge.

@vivi90 You gave us many details about your environment, but missed the most crucial piece of info: the error-report itself..
Pasting the backtrace here will give us some clue as to where the error could have originated from.

[なつき]

sass-embedded does not use ffi. So this error is likely unrelated to sass-embedded. Looking at Gemfile.lock, only sassc uses ffi. To some degree sassc is loaded unconditionally regardless of whether sass-embedded is chosen or not. So that the problem is likely happening during sassc.

E.g. Try bundle exec ruby -e 'require "sassc"' and see if you get the same error.
