Question - installing gems

[Falroi]

When running bundle install --path .vendor/bundle --without development in the root directory of the repository I'm receiving this error:

Traceback (most recent call last):
2: from /usr/bin/bundle:23:in <main>' 1: from /Library/Ruby/Site/2.6.0/rubygems.rb:284:in activate_bin_path'
/Library/Ruby/Site/2.6.0/rubygems.rb:265:in `find_spec_for_exe': can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)

I tried digging around a little nothing I came across seemed to be a fix for my environment:

Ruby 2.6.3
Gem 3.3.9
OSX 10.15.7

Any assistance would be greatly appreciated.

I believe I've fixed this by running: gem install bundler --user-install and then exporting it to path. In my case that looked like:
echo 'export PATH="/Users/myuser/.gem/ruby/2.6.0/bin:$PATH"' >> ~/.zshrc
