macos - I have an old Rails app that won't load in Mac Terminal anymore

Question

I have a Rails app that I made four years ago. I'm trying to load it now in Terminal on Mac and it won't load. When I type rails console I get the following:

Array values in the parameter to `Gem.paths=` are deprecated. Please use a String or nil. An Array ({"GEM_PATH"=>["/Users/[username]/.rvm/gems/ruby-2.4.0", "/Users/[username]/.rvm/gems/ruby-2.4.0@global"]}) was passed in from bin/rails:3:in `load' /Users/[username]/.rvm/gems/ruby-2.4.0/gems/activesupport-4.2.5/lib/active_support/core_ext/numeric/conversions.rb:121: warning: constant ::Fixnum is deprecated

then some other stuff, and then the last line:

from /Users/[username]/.rvm/gems/ruby-2.4.0/gems/spring-2.1.1/lib/spring/application/boot.rb:19:in `<top (required)>' from /Users/[username]/.rvm/rubies/ruby-2.4.0/lib/ruby/site_ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/[username]/.rvm/rubies/ruby-2.4.0/lib/ruby/site_ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require' from -e:1:in `<main>'

What do I need to do here?

[Update - a commenter asked me to post the whole error message so here's what it was:]
