rvm not installing ruby-2.2; Error running '__rvm_make -j4' - ruby

Question

When I try to download Cocoapods, it says:
XXXX: ~ XXX$ sudo gem install cocoapods
Password:XX
ERROR: Error install cocoapods:
minitest requires Ruby version ~> 2.2.
Then I try every way to install ruby but it gives me this:
Searching for binary rubies, this might take some time.

please read /Users/vishaljayakumar/.rvm/log/1581558007_ruby-2.2.5/make.log
There has been an error while running make. Halting the installation.
What do I do?
I have done literally every solution here and it doesn't work:
Github Error Page
Let me just name some of them just for you to see.
rvm get head
rvm mount -r https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.8.tar.bz2
rvm get stable; rvm reload; rvm install "ruby-2.2.X"
anything to do with openssl(I have no idea what it is)
rvm install ruby-2.6.5 --with-openssl-dir='{directory of openssl}
sudo xcode-select -s /Applications/Xcode.app
rvm install 2.6.4
brew install homebrew/portable-ruby/portable-openssl
rvm reinstall ruby-2.3.1 --with-openssl-dir=/usr/local/opt/portable-openssl/
Please give me a solution that is not in here(or one of the above).
I am a little desperate as I have wasted a lot of time on these commands!
I am free to any answers or comments!!!!!
