我正在尝试通过 OmniAuth 让 OAuth2 为我的 Sinatra 应用程序工作，但收到：

LoadError: cannot load such file -- omniauth-twitter


我正在关注这些示例，尽管它们有点不一致
- http://recipes.sinatrarb.com/p/middleware/twitter_authentication_with_omniauth app.rb
- https://github.com/intridea/omniauth/wiki/Sinatra-示例

Sinatra 食谱告诉我将构建器放在“配置执行”中，而官方示例没有，但有“使用 Rack::Session::Cookie”

我已经在网上搜索寻找好的 Sinatra OmniAuth 示例，但是似乎它有利于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


我得到的完整错误

Shotgun was the culprit. Works fine when I run 'ruby app.rb' from the terminal, but with shotgun I receive the error.

看起来没有安装omniauth-twitter gem。例如：

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

如果您使用捆绑器，或者在您的项目中有意义的任何内容，您需要将gem install omniauth-twitter其包含在您的 gemspec 中。
