What is this error that I am receiving?

I have no clue what is going on? I’m starting a new project and getting the following message in terminal:

-bash: /Users/christians/.rvm/scripts/initialize: No such file or directory
-bash: /Users/christians/.rvm/scripts/hook: No such file or directory

then

Deprecation: The 'gems' configuration option has been renamed to 'plugins'. Please update your config file accordingly.

then

Both messages have nothing in common, the first is a change introduced in Jekyll 3.5.0, from now on you write:

plugins:
  - jekyll-feed
  - jekyll-sitemap
  - jemoji

For fs-event, check this issue : Jekyll error on jekyll serve -- fsevent: running worker failed · Issue #6189 · jekyll/jekyll · GitHub

Okay—there’s no need for me to include:
-jekyll-sitemap
and
-jemoji , right?

Correct! Simply rename the gems key in /faculty-one/_config.yml to plugins
