Question

在一些教程的帮助下，我创建了我的第一个简单的gem，它将Sass / CSS文件添加到应用程序的assets / stylesheets目录中。

这很尴尬，但问题是我不知道如何在应用程序中运行我的宝石。

gemspec：

# coding: utf-8
lib = File.expand_path('../lib', __FILE__)
$LOAD_PATH.unshift(lib) unless $LOAD_PATH.include?(lib)
require 'example/version'

Gem::Specification.new do |spec|
  spec.name          = "Example"
  spec.version       = Example::VERSION
  spec.authors       = ["***"]
  spec.email         = ["***"]
  spec.description   = %q{Provide CSS styles}
  spec.summary       = %q{Provide CSS styles}
  spec.homepage      = ""
  spec.license       = "MIT"

  spec.files         = `git ls-files`.split($/)
  spec.executables   = spec.files.grep(%r{^bin/}) { |f| File.basename(f) }
  spec.test_files    = spec.files.grep(%r{^(test|spec|features)/})
  spec.require_paths = ["lib"]

  spec.add_development_dependency "bundler", "~> 1.3"
  spec.add_development_dependency "rake"
  spec.add_development_dependency "redcarpet", "~> 1.17"
  spec.add_development_dependency "yard", "~> 0.7.5"
end

example.rb：

require "example/version"

module Example

    def self.install
        original_dir = Dir["/lib/example/*.css.scss"]
        original_dir.each do |f|
            name = File.basename('main', '.css.scss')
            destination_dir = "/app/assets/stylesheets/#{name}"
            FileUtils.cp(main, destination_folder)
        end
    end

end

Rake文件：

require "bundler/gem_tasks"
require 'yard'
YARD::Rake::YardocTask.new

我相信我应该写一些rake任务，但我不确定我该怎么做。

谢谢！

我学会了如何解决我的问题。从gem文件运行ruby代码的最佳方法是将其移动到rails生成器。例如，创建包含代码的文件lib/generators/initializer_generator.rb（我举了一个例子）：

class InitializerGenerator < Rails::Generators::Base
  def create_initializer_file
    create_file "config/initializers/initializer.rb", "# Add initialization content here"
  end
end

然后将您的gem添加到Gemfile，安装它并运行rails g initializer
