Bundler could not find compatible versions for gem "rubygems "

[arkag]

I'm sure this is stupid, but I can't find any information when searching for this specific error, and I'm green when it comes to Ruby.

Build error:

👍 ENTRYPOINT HAS STARTED—INSTALLING THE GEM BUNDLE

Bundler could not find compatible versions for gem "rubygems�":
  In Gemfile:
    rubygems� (= 2.6.11)

    jekyll (>= 4.1.1, ~> 4.1) was resolved to 4.1.1, which depends on
      rubygems� (>= 2.7.0)

My Gemfile:

source 'https://rubygems.org'
gem 'jekyll', '~> 4.1', '>= 4.1.1'
gem 'jekyll-analytics'
gem 'noir-for-jekyll'

Looks like maybe you need to update your version of rubygems. What does gem -v say? Can get the latest version with gem update --system
