So while doing jekyll build I got traceback as
Bundler could not find compatible versions for gem “sassc”: (Bundler::VersionConflict)
In snapshot (Gemfile.lock):
sassc (= 2.2.1)
jekyll was resolved to 4.0.0, which depends on
jekyll-sass-converter (~> 2.0) was resolved to 2.1.0, which depends on
sassc (> 2.0.1, < 3.0)
bundle update will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
Later doing bundle update
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/bundler/spec_set.rb:91:in `block in materialize’: Could not find tzinfo-1.2.7 in any of the sources (Bundler::GemNotFound)
Is the gemfile up to date?
