[Ruby] The gem should have been installed in vendor / bundle, but an error occurs in require

Background

I wanted to learn a little about scraping, Implemented with reference to Making a scraping source in 20 minutes using Ruby. Since it says "Gem should be installed under vendor / bundle." Added --path vendor / bundle option when doing bundle install as instructed.

Error occurred

If you write the code as in the article to main.rb and execute main.rb,

training $ ruby main.rb 
Traceback (most recent call last):
	2: from main.rb:2:in `<main>'
	1: from /Users/yusaku/.rbenv/versions/2.6.0/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require'
/Users/yusaku/.rbenv/versions/2.6.0/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- nokogiri (LoadError)

It says 'require': cannot load such file --nokogiri (LoadError), nokogiri has bundle installed under vender / bundle.

training $ ls vendor/bundle/ruby/2.6.0/gems/
byebug-11.1.3		method_source-1.0.0	nokogiri-1.10.10	pry-byebug-3.9.0
coderay-1.1.3		mini_portile2-2.4.0	pry-0.13.1

Solution

If you look closely at the details of the error, It looks like you are looking for a subordinate to /Users/yusaku/.rbenv/. I was surprised at that, but I didn't do bundle exec.

training $ bundle exec ruby main.rb

Now I was able to run main.rb without any errors (and also require "nokogiri"). By doing bundle exec, it looks like they searched for the gem under the same directory.
