Ruby LoadError:无法加载此类文件--omniauth twitter

我正试图通过OmniAuth让OAuth2为我的Sinatra应用程序工作，但收到：

LoadError: cannot load such file -- omniauth-twitter

我遵循这些示例，尽管它们有点不一致
- app.rb
-

Sinatra配方告诉我将构建器放在“configure do”中，而官方示例没有，但有“use Rack:：Session:：Cookie”

我已经在网上搜索了好的Sinatra OmniAuth示例，但它似乎更倾向于Rails

require "omniauth"
require "omniauth-twitter"

# OAuth2 configuration
use Rack::Session::Cookie
use OmniAuth::Builder do
  provider :twitter, 'CONSUMER_KEY', 'CONSUMER_SECRET'
end

before do
# we do not want to redirect to twitter when the path info starts
# with /auth/
  pass if request.path_info =~ /^\/auth\//

# /auth/twitter is captured by omniauth:
# when the path info matches /auth/twitter, omniauth will redirect to twitter
  redirect to('/auth/twitter') unless current_user
end

get '/auth/twitter/callback' do
# probably you will need to create a user in the database too...
  session[:uid] = env['omniauth.auth']['uid']
# this is the main endpoint to your application
  redirect to('/')
end

get '/twitter' do
  erb "<a href='/auth/twitter'>Sign in with Twitter</a>"
end

# Support for OAuth failure
  get '/auth/failure' do
  flash[:notice] = params[:message] # if using sinatra-flash or rack-flash
  redirect '/'
end

需要“omniauth”
需要“omniauth twitter”
#OAuth2配置
使用Rack:：Session:：Cookie
使用OmniAuth:：Builder do
提供者：twitter、“消费者密钥”、“消费者秘密”
结束
在做之前
#我们不希望在路径信息启动时重定向到twitter
#使用/auth/
如果请求，则传递。路径\信息=~/^\/auth\//
#/auth/twitter由omniauth捕获：
#当路径信息匹配/auth/twitter时，omniauth将重定向到twitter
重定向到（'/auth/twitter'），除非当前用户
结束
获取“/auth/twitter/callback”do
#可能您还需要在数据库中创建一个用户。。。
会话[:uid]=env['omniauth.auth']['uid']
#这是应用程序的主要端点
重定向到（“/”）
结束
获取“/twitter”do
雇员再培训局“
结束
#对OAuth失败的支持
获取“/auth/failure”do
闪存[：注意]=参数[：消息]#如果使用sinatra闪存或机架闪存
重定向“/”
结束

我得到的全部错误

看起来好像没有安装omniauth twitter gem。例如：

> require "blahblahblah"
LoadError: cannot load such file -- blahblahblah

您需要

gem安装omniauth twitter

，如果您正在使用bundler，请将其包含在您的gemspec中，或者在您的项目中有意义的任何内容。
