Sto provando a distribuire un'app a Heroku che utilizza il web driver Watir. Funziona con successo localmente. Secondo le risposte a questa domanda: Can you deploy Watir on Heroku to generate HTML Snapshots? If so, how?, puoi farlo. Ho seguito i passaggi da questa risposta https://stackoverflow.com/a/21267376/3192470. Il mio app.rb assomiglia a questo:Applicazione Watir distribuita su heroku
require "sinatra"
require "rubygems"
require "shotgun"
require "rake"
require "watir"
get '/sending_out' do
browser = Watir::Browser.new :phantomjs
erb :index
end
Ma si blocca quando schierato a Heroku con questi registri:

E anche quando spingo a Heroku che pensa che sia un'applicazione phantomjs:
PhantomJS app detected
Cosa si può fare per tutto questo? È possibile eseguire Watir da Heroku?
EDIT: risposta da supporto Heroku:
Watir richiede selenio, che richiede un server X installato sulla macchina. Poiché i nostri dynos non sono progettati per avviare applicazioni grafiche, non hanno installato alcun server X e pertanto non possono installare Selenium. Pertanto, temo che non sarà possibile utilizzare Watir nella tua applicazione.
fai a sapere se si potrebbe lavorare se si esegue watir del browser senza testa? –
@DavidGeismar, vuoi dire con la gemma senza testa? Ho eseguito con successo watir con gemma senza testa su vps senza testa, ma non heroku. Penso che sì, puoi farlo anche su heroku con qualche altro buildpack. – lakesare
Non sto usando la gemma senza testa, ma finalmente con il driver fantasma fantasma, ma non riesco ancora a implementarlo su heroku ... Se hai qualche idea per aiutarmi http: // StackOverflow.it/questions/33156381/cant-deploy-rails-app-on-heroku-after-installation-buildpacks –
