使用Ruby 3（RVM环境）执行脚本时遭遇LoadError问题

Ruby脚本执行require 'activesupport'时出现LoadError，但各类检查均确认该gem已成功安装，无论使用bundle exec还是rvm do执行脚本，错误均一致。

命令输出 #

$ 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>'

脚本内容 #

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

环境版本信息 #

• rvm 1.29.12
• ruby 3.1.2p20
• gem 3.3.7
• bundle 2.3.7
• macOS 13.5.2 (M2)
