Why am I getting this error (Error running '__rvm_make -j12') when installing RVM?

Question

When running the install script for Ruby Version Manager I keep getting this error:

Error running '__rvm_make -j12',
please read /Users/wikipediabrown/.rvm/log/1701736892_ruby-3.0.0/make.log

There has been an error while running make. Halting the installation.

I can't figure out what I'm doing wrong. The logs are cryptic as heck and don't tell me anything.

The end of the log is as follows:

ld: warning: ignoring duplicate libraries: '-lruby.3.1'

Turns out, it is a problem with having Java messed up on your machine. For some context the j12 could be j* meaning j anything (j10, j11, j12 etc.). That just telling you that your Java installation is messed up and nobody wants to tell you. If you're running anything later than Mac OS X 10.6 you're gonna find that you need to install it yourself. It's hard to remember that when you've been on the same machine since the slave ships. But I've got a solution for you.

If you just run:

brew install openjdk

and definitely not:

brew install java

Ayo, for real!!! don't run that stuff player

and as per the Caveats section it's as easy as pie to miss, you should run this:

For the system Java wrappers to find this JDK, symlink it with
  sudo ln -sfn /opt/homebrew/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

you'll be alright after that. This is just a failure of correct error messaging. Go on and live a good life after this y'all.
