LoadError:無法加載此類文件— roo

[英]LoadError: cannot load such file — roo

在過去的2.5天里,我一直在排除Ruby on Rails應用程序中的問題。 在線使用資源,然后在stackoverflow上使用資源,我已經取得了進步,但是仍然沒有解決問題。

難題:我無法將roo gem或電子表格gem加載到我的Rails應用程序中。

我已經成功地使用了IRB終端中的電子表格gem來執行一個簡單的腳本,並將從電子表格中讀取的數據輸出到終端。 這表明該寶石已正確安裝並且可以正常運行。

盡管如此,Rails似乎並不想識別這兩個寶石。 這是在多次嘗試正確配置依賴項版本和開發依賴項之后進行的。

我的歡迎控制器:

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

gem 'roo', '2.7.0'

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

我嘗試編輯文件以如下更改spec.require_paths變量:

spec.require_paths = ['lib/roo']

但是跑步后我沒有成功

>> bundle update
>> bundle install

我通往roo gem的道路:

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

我正在運行Lubuntu衍生產品LXLE Linux。

我嘗試了以下問題的解決方案,但似乎沒有任何效果:

Ruby Roo LoadError:無法加載此類文件-電子表格/注釋

無法加載此類文件-Raillite上的ruby上的sqlite3 / sqlite3_native(LoadError)

似乎我已經根據rubygems.org上的文檔正確設置了依賴項。

有人遇到過這樣的問題嗎? 最近幾天,我一直在關注這個問題,所以也許我正在掩蓋重要的事情,所以我認為編寫並詢問有關問題將有所幫助。 我今天還要花幾個小時。

您可以檢查兩件事:

  • gemset:確保將gem安裝在您所在的gemset中
  • 紅寶石版本:確保寶石安裝時使用的是相同的紅寶石版本。

要進行檢查,請從您的項目目錄中執行“ gem list”,然后查看是否列出了gem。

如果不在同一個gemset中,則可以使用:

rvm use gemset_name 

如果不是同一Ruby版本,則將其設置為使用Ruby版本,例如2.3.3。

rvm use 2.3.3
