有几种方法可以在你自己的gem中指定gem依赖项。
如果你的gem名为my_awesome_tem，那么在my_awesome_gem.gemspec文件中，你可以像这样指定开发时和运行时的依赖关系：

# my_awesome_gem.gemspec
Gem::Specification.new do |s|
  s.name = "my_awesome_gem"
  s.version = "0.1"

  s.authors = ["My Name"]
  s.description = "just does awesome things"
  s.files         = Dir['Gemfile', 'Rakefile', 'README.md','app/**/*','config/**/*','db/**/*','lib/**/*','spec/**/*']
  s.summary = "awesome gem"

  s.add_runtime_dependency("rails", ["> 7.0.0"])
  s.add_development_dependency("sqlite3-ruby")
  s.add_development_dependency("capybara")
  s.add_development_dependency("rspec-rails", [">= 2.0.0"])
  s.add_development_dependency("faker")
  s.add_development_dependency("factory_bot_rails")
  s.add_development_dependency("database_cleaner")
  s.add_runtime_dependency("haml")
end

# Gemfile
source "http://rubygems.org"
gemspec

或者，您可以将它们包含在gem的Gemfile中，与Rails应用程序相同
