Ruby 宝石建造。。。如何在gem中包含供应商目录？

我运行

gem build mygem.gempec

，不包括供应商目录。如何将其包含在我的宝石中？如果我想用gem打包所有依赖项，我假设我需要包含vendor dir

我认为这与

Dir['vendor/**]

有关。。。我知道这是错误的

我的gempec文件：

lib = File.expand_path('../lib', __FILE__)
$LOAD_PATH.unshift(lib) unless $LOAD_PATH.include?(lib)
require 'fpa/fix_filename/version'

Gem::Specification.new do |spec|
  spec.name          = "fpa-fix_filename"
  spec.version       = Fpa::FixFilename::VERSION
  spec.authors       = ["na"]
  spec.email         = ["na"]

  spec.summary       = %q{A Class to fix bad file names -- includes a binary for command line use.}
  spec.description   = %q{}
  spec.license       = "MIT"

  spec.files = Dir['lib/fpa/**/*'] + Dir['bin/*'] + Dir['vendor/**']

  spec.bindir        = "bin"
  spec.executables   = spec.files.grep(%r{^bin/}) { |f| File.basename(f) }

  spec.require_paths = ["lib"]

  spec.add_runtime_dependency "micro-optparse", "~> 1.2.0"

  spec.add_development_dependency "bundler", "~> 1.8"
  spec.add_development_dependency "rake", "~> 10.0"
end

你试过这样吗

Dir['vendor/**/*']

啊。。。你知道吗。。。是的，但现在我看到了一个语法错误，并假设这是因为供应商目录的深度超过两个目录，我需要另一种方法来处理更深的目录。谢谢
