LoadError:无法加载这样的文件 - roo
问题描述:
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*,我已经取得了进展,但仍然没有解决问题。LoadError:无法加载这样的文件 - roo
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

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 = ['[email protected]', '[email protected]']
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.reject! { |fn| fn.include?('test/files') }

spec.add_development_dependency 'minitest', '~> 5.4', '>= 5.4.3'

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
这是可能的,这是一个Rails 3与Rails 5的东西。按照预期制作新的Rails 5项目并加载“roo”是否工作正常? – tadman
Hey tadman - 我从一个Rails 5.0.2项目开始,但是在使用Rails版本时,bundle抱怨了一些roo gem的依赖关系。也许我只需要一个干净的项目 - 我会尝试你的建议。谢谢 – Nathan
如果您在运行当前版本的Ruby的新项目中遇到可重现问题,则可能需要提交问题,但在此之前请务必尝试并尝试不同的组合。希望你能解决它! – tadman
