Could not find 'bundler' (2.2.16) required by your Gemfile.lock

You need to install the version listed in the Gemfile.lock file to fix this error: ```bash gem install --force "bundler:$(grep -A 1 "BUNDLED WITH" Gemfile.lock | tail -n 1)" ``` In a Dockerfile you could run it like this: ```bash RUN gem install --force "bundler:$(grep -A 1 "BUNDLED WITH" Gemfile.lock | tail -n 1)" rake && \ bundle config set without development test && \ bundle config set --local deployment 'true' && \ bundle install --jobs 5 --retry 5 && \ bundle clean --force ```
