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 –

Sì, è possibile! Segui i passaggi di questo articolo: https://github.com/edelpero/watir-examples/blob/master/watir_on_heroku.md.

Poco:

$ heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git 
$ touch .buildpacks 

Quindi aggiungere alla directory appena creata .buildpacks queste righe:

https://github.com/heroku/heroku-buildpack-ruby 
https://github.com/stomita/heroku-buildpack-phantomjs 

Poi nel terminale:

$ heroku config:set PATH="/usr/local/bin:/usr/bin:/bin:/app/vendor/phantomjs/bin" 
$ heroku config:set LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/lib:/app/vendor/phantomjs/lib 

Spingere quindi queste modifiche Heroku e

Watir::Browser.new :phantomjs 

con il solito codice Watir seguente dovrebbe funzionare!

Articolo interessante. Heroku consente più pacchetti di build dalla scatola con 'heroku buildpacks: aggiungi --index 1 heroku/ruby'. Ma nessuno dei webdriver funziona per me, producono qualcosa come "ChildProcess :: LaunchError - Nessun file o directory" che trascura i file esiste e ha + x su di essi. – lifecoder

heroku-buildpack-multi è deprecato, al giorno d'oggi è possibile aggiungere più buildpacks di Heroku e utilizzare il phantomjs buildpack in questo modo:

$ heroku buildpacks:add https://github.com/stomita/heroku-buildpack-phantomjs 

dovrebbe funzionare!
