Make build fails -> nokorigi issue

[nabello]

Hi everyone, I am using a Mac with the latest version of Docker for Mac installed to follow the LinkedIn Learning course DevSecOps: Automated Testing which references the use of this repository. I follow the instructions in the course:

1. Checkout this repository
2. Change directories into the repository folder
3. Execute the make build command which results in the following output for me:

gauntlt-docker % make build

Any help to resolve these errors would be appreciated.

Similar here:

When installing gauntlt with sudo make build, I get:

ERROR: Error installing gauntlt: The last version of nokogiri (~> 1.8, >= 1.8.1) to support your Ruby & RubyGems was 1.15.6. Try installing it withgem install nokogiri -v 1.15.6and then running the current command again nokogiri requires Ruby version >= 3.0, < 3.4.dev. The current ruby version is 2.7.0.0.

I did gem install nokogiri -v 1.15.6 and it completed successfully, but the error above persists. Please help. Thanks.
