问题
I am trying to install ruby using below commands
source ~/.rvm/scripts/rvm
rvm install 2.3.7
I encountered this error while I was trying to install ruby 2.3.7 in MacOs Catalina 10.15.5
rvm install 2.3.7
Warning, new version of rvm available '1.29.10', you are using older version '1.29.9'.
You can disable this warning with: echo rvm_autoupdate_flag=0 >> ~/.rvmrc
You can enable auto-update with: echo rvm_autoupdate_flag=2 >> ~/.rvmrc
You can update manually with: rvm get VERSION (e.g. 'rvm get stable')
Searching for binary rubies, this might take some time.

Please help as I am not sure what is going wrong

See this issue comment
It looks like old ruby version requires an older version of openSSL and also it has to be build with that version pointing in --with-openssl-dir
You might try this:
brew install rbenv/tap/openssl@1.0
PKG_CONFIG_PATH=/usr/local/Cellar/openssl@1.0/1.0.2t/lib/pkgconfig \
rvm install 2.3.7 \
--with-openssl-dir=/usr/local/Cellar/openssl@1.0/1.0.2t \
--with-openssl-lib=/usr/local/Cellar/openssl@1.0/1.0.2t/lib \
--with-openssl-include=/usr/local/Cellar/openssl@1.0/1.0.2t/include --rubygems ignore

For older versions of ruby, you might want to use a docker + docker-compose development workflow like this one. https://rollout.io/blog/running-rails-development-environment-docker/
You should be able to install ruby 2.3 that way and you won't have to deal with these types of weird errors, plus you'll learn docker. You should be able to develop and see the changes in the images. IIRC the only issue is on gem changes you need to run a new docker-compose build.
