Bundler Error when attempting Capistrano Deployment - ruby-on-rails

Question

I am attempting to deploy a ruby on rails web app to a staging server but continue to get the error: bundle stderr: /home/deploy/.rvm/rubies/ruby-2.7.0/lib/ruby/2.7.0/rubygems.rb:275:in `find_spec_for_exe': Could not find 'bundler' (1.16.1) required by your /home/deploy/apps/MYAPP/releases/20201230174246/Gemfile.lock. (Gem::GemNotFoundException)
I have attempted to install bundler on the server directly, and even after doing so it continues to fail with the same error. Full error log and deploy.rb below.

Server Info:
Ubuntu 20.04
Bundler is confirmed to be installed on the server.
Gem Info
Do I perhaps need to change the default version of bundler?
I can see the release folders get generated, but because of the failure no current sym_link is ever created and deployment fails. Is there a server setup step I'm missing for the initial cap deploy to a new staging server? Do I need to have bundler installed in a specific server location in order for cap to "find" it?

Answer 1

I was able to get past this blocker. The ultimate issue is that I had to log into the correct shell and run gem install bundler:1.16.1.
In order to log into the bash I used this command:
/bin/bash --login
Then run gem install:
gem install bundler:1.16.1
