The following Ruby script gives me a LoadError
when it requires the activesupport
gem, but everything else is showing me that it's installed. I get the same error whether I run it through bundle exec
or rvm do
.
$ cat Gemfile | grep activesupport
gem 'activesupport'
$ bundle show activesupport
/Users/2b-software-mac/.rvm/gems/ruby-3.1.2/gems/activesupport-7.0.6
$ bundle exec ruby my_ruby_script.rb
Can I find the gem?
#<Bundler::StubSpecification name=activesupport version=7.0.6 platform=ruby>
Can I require the gem?
my_ruby_script.rb:4:in `require': cannot load such file -- activesupport (LoadError)
from my_ruby_script.rb:4:in `<main>'
puts 'Can I find the gem?'
puts Gem::Specification.find_all{ |g| g.name.include? 'activesupport' }
puts 'Can I require the gem?'
require 'activesupport'
The gem has to be loaded like this (note the underscore):
require "active_support"
