下面的Ruby脚本在需要activesupport gem时给了我一个LoadError，但其他所有东西都显示它已经安装。无论我是通过bundle exec还是rvm do运行它，都会得到相同的错误。

$ 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>'

脚本

puts 'Can I find the gem?'
puts Gem::Specification.find_all{ |g| g.name.include? 'activesupport' }
puts 'Can I require the gem?'
require 'activesupport'
