LoadError：无法加载这样的文件 - roo

Question

我在过去的2.5天里一直在解决Ruby on Rails应用程序中的一个问题。在线上使用资源并在这里使用了stackoverflow，我已经取得了进展，但仍然没有解决问题。

窘境：我无法将roo gem或电子表格gem加载到我的Rails应用程序中。

我已成功使用IRB终端中的电子表格gem执行简单脚本，并将从电子表格读取的数据输出到终端。这表明gem正确安装并正常工作。

尽管如此，Rails似乎并不想识别这两个宝石。这是在很多尝试正确配置版本的依赖关系和开发依赖关系之后。

我欢迎控制器：

class WelcomeController < ApplicationController 
    require 'roo' 

    def index 
     puts "Hello Rails!" 
    end 
end 

我Gemfile：

source 'https://rubygems.org' 

git_source(:github) do |repo_name| 
    repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/") 
    "https://github.com/#{repo_name}.git" 
end

gem 'roo', '2.7.0' 

gem 'spreadsheet', '1.1.0' 

我roo.gemspec文件：

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

Gem::Specification.new do |spec| 
    spec.name   = 'roo' 
    spec.version  = Roo::VERSION 
    spec.authors  = ['Thomas Preymesser', 'Hugh McGowan', 'Ben Woosley', 'Oleksandr Simonov', 'Steven Daniels'] 
    spec.email   = ['ruby.ruby.ruby.roo@gmail.com', 'oleksandr@simonov.me'] 
    spec.summary  = 'Roo can access the contents of various spreadsheet files.' 
    spec.description = "Roo can access the contents of various spreadsheet files. It can handle\n* OpenOffice\n* Excelx\n* LibreOffice\n* CSV" 
    spec.homepage  = 'http://github.com/roo-rb/roo' 
    spec.license  = 'MIT' 

    spec.files   = `git ls-files -z`.split("\x0") 
    spec.files.reject! { |fn| fn.include?('test/files') } 
    spec.require_paths = ['lib'] 

    spec.add_dependency 'nokogiri', '~> 1' 
    spec.add_dependency 'rubyzip', '~> 1.1', '< 2.0.0' 

    spec.add_development_dependency 'rake', '~> 10.1' 
    spec.add_development_dependency 'minitest', '~> 5.4', '>= 5.4.3' 
    spec.add_development_dependency 'rack', '~> 1.6', '< 2.0.0' 
end 

我试着编辑改变spec.require_paths变量文件如下：

spec.require_paths = ['lib/roo'] 

但我不得不跑

>> bundle update 
>> bundle install 

我的路径Roo的宝石后，没有成功：

/var/lib/gems/2.3.0/gems/roo-2.7.0/ 

我跑LXLE Linux上，Lubuntu衍生物。

我试图对这些问题找到解决方案，但似乎没有为我工作：

Ruby roo LoadError: cannot load such file -- spreadsheet/note

cannot load such file -- sqlite3/sqlite3_native (LoadError) on ruby on rails

好像我已按有关RubyGems的文档正确设置我的依赖.ORG。

有没有人有这样的问题？过去几天我一直在研究这个问题，所以也许我会重申一些重要的东西，所以我认为写它并询问它会有所帮助。今天我会花更多的时间在上面。

有两件事情你可以检查：

• 宝石：确保创业板安装在其中你在
• 红宝石版相同的宝石：确保创业板安装在同一红宝石版本正如你使用的那样。

要检查，执行您的项目目录中的'宝石列表'，看看是否列出了宝石。

如果不是在同一个宝石，你可以使用：

rvm use gemset_name 

如果不是在同一个红宝石版本，将其设置为使用红宝石版本，例如2.3.3

rvm use 2.3.3
