Getting errors during setup

[wlsf82]

I'm trying to set up the project to start the exercise, but I'm not able to run bin/setup.

When using Ruby 2.2.1, I get the following error:

Could not load OpenSSL.
You must recompile Ruby with OpenSSL support or change the sources in your Gemfile from 'https' to 'http'. Instructions for compiling with OpenSSL using RVM are available at rvm.io/packages/openssl.

And when using Ruby 2.5.3 or 2.6.0, I get the following error:

Fetching gem metadata from https://rubygems.org/........
