--cache unvailable in CLI

From README.md:

html-proofer/README.md

Line 397 in 3b93cea

On the CLI, you can provide the `--cache` argument to set the configuration. This is parsed using `JSON.parse` and mapped on top of the default configuration values so that they can be overridden.

On the CLI, you can provide the --cache argument to set the configuration. This is parsed using JSON.parse and mapped on top of the default configuration values so that they can be overridden.

However, when passing the --cache argument to the CLI, HTMLProofer blows up:

htmlproofer 3.19.4 | Error:  Whoops, we can't understand your command.
htmlproofer 3.19.4 | Error:  invalid option: --cache
htmlproofer 3.19.4 | Error:  Run your command again with the --help switch to see available options.

@asbjornu, you are still running on htmlproofer 3.19.4, whereas the README refers to the last major v4 release of HTMLProofer

If you want to know how to use that version, follow

You are quite correct, @riccardoporreca. I was certain I was on the latest version since I have Dependabot configured, but I had a custom Checker gem that had a dependency on html-proofer ~> 3.0 which blocked the upgrade to v4. Sorry!
