Unable to install curb gem on macOS

Question

I'm unable to install curb on my Mac. When I enter gem install curb I get this error

ERROR:  Could not find a valid gem 'curb' (>= 0), here is why:
      Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: tlsv1 alert protocol version (https://rubygems.org/latest_specs.4.8.gz)

I looked at a similar question with a similar error message reported ("Unable to download data from https://rubygems.org/") and tried the suggested solution, but it seems I don't have rvm. I'm also not sure if the origin of these two issues is the same.

What am I missing?

UPDATE: I did some more digging and suspect it's my version of OpenSSL (I have OpenSSL 0.9.8zh 14 Jan 2016) that I seem not to be able to update any further. I'm on macOS 10.11.6 (El Capitan).

So I tried a less secure option with

$ sudo gem sources -a http://rubygems.org
Password:
https://rubygems.org is recommended for security over http://rubygems.org

Do you want to add this insecure source? [yn]  y 
http://rubygems.org added to sources

After that I tried above command again

$ sudo gem install curb

Just not sure if the last error message now means the install was incomplete or not.

Does this answer your question? [SSL Error When installing rubygems, Unable to pull data from 'https://rubygems.org/](https://stackoverflow.com/questions/19150017/ssl-error-when-installing-rubygems-unable-to-pull-data-from-https-rubygems-o) — Sara Fuerst, Sep 17 '21 at 00:46
Thanks. It seems I can't execute the ```rvm``` command (says ```rvm: command not found```. — Alex Ixeras, Sep 17 '21 at 03:09
Do I need to install rvm first? If so, where do I get it from? — Alex Ixeras, Sep 17 '21 at 03:14
If you don't use RVM follow the instructions under "For non RVM users" — Sara Fuerst, Sep 17 '21 at 15:23
I've tried that too and when I enter ```security find-certificate -a -p /Library/Keychains/System.keychain > "$cert_file"``` I get ```-bash: /System/Library/OpenSSL/cert.pem: Operation not permitted``` — Alex Ixeras, Sep 17 '21 at 15:27
