[英]LoadError: cannot load such file — roo
在过去的2.5天里,我一直在排除Ruby on Rails应用程序中的问题。 在线使用资源,然后在stackoverflow上使用资源,我已经取得了进步,但是仍然没有解决问题。
难题:我无法将roo gem或电子表格gem加载到我的Rails应用程序中。
我已经成功地使用了IRB终端中的电子表格gem来执行一个简单的脚本,并将从电子表格中读取的数据输出到终端。 这表明该宝石已正确安装并且可以正常运行。
尽管如此,Rails似乎并不想识别这两个宝石。 这是在多次尝试正确配置依赖项版本和开发依赖项之后进行的。
我的欢迎控制器:
class WelcomeController < ApplicationController
require 'roo'
def index
puts "Hello Rails!"
end
end
我的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

我的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 'minitest', '~> 5.4', '>= 5.4.3'
spec.add_development_dependency 'rack', '~> 1.6', '< 2.0.0'
end
我尝试编辑文件以如下更改spec.require_paths变量:
spec.require_paths = ['lib/roo']
但是跑步后我没有成功
>> bundle update
>> bundle install
我通往roo gem的道路:
/var/lib/gems/2.3.0/gems/roo-2.7.0/
我正在运行Lubuntu衍生产品LXLE Linux。
我尝试了以下问题的解决方案,但似乎没有任何效果:
Ruby Roo LoadError:无法加载此类文件-电子表格/注释
无法加载此类文件-Raillite上的ruby上的sqlite3 / sqlite3_native(LoadError)
似乎我已经根据rubygems.org上的文档正确设置了依赖项。
有人遇到过这样的问题吗? 最近几天,我一直在关注这个问题,所以也许我正在掩盖重要的事情,所以我认为编写并询问有关问题将有所帮助。 我今天还要花几个小时。
您可以检查两件事:
要进行检查,请从您的项目目录中执行“ gem list”,然后查看是否列出了gem。
如果不在同一个gemset中,则可以使用:
rvm use gemset_name
如果不是同一Ruby版本,则将其设置为使用Ruby版本,例如2.3.3。
rvm use 2.3.3
