quando si tenta di installare la gemma watir o watir-webdriver su Windows 7 tramite cygwin, ottenendo una lunga traccia di stack C con menzioni di problemi "socket W32"

Durante l'esecuzione:

$ gem install watir

su Windows 7 (cygwin), ho capito

ERROR:  Error installing watir:

Spero che questo sia solo un pacchetto di sviluppo che non ho ancora installato. Grazie per avergli dato un colpo.

Stack Overflow mi richiede di scrivere un po 'di più perché c'è così tanto codice in alto. Ma la verità è che sono già fuori di testa con questo dato che di solito sono uno sviluppatore unix-only. Devo usare Windows per questo perché l'applicazione web con cui sto lavorando SOLO funziona su Internet Explorer, ma non su Windows 8.

Per tua informazione sto eseguendo software a 64 bit su hardware a 64 bit.

Ho scritto le istruzioni su come installare Watir su Windows: https://github.com/watir/watirbook/blob/master/installation/windows.md

Non è completamente aggiornato, ma dovrebbe funzionare.

Vedo che stai cercando di crearlo con cygwin gcc e nella mia esperienza non ci sono molte possibilità che funzioni. Dovresti provare ruby ​​+ devkit da rubyinstaller.org, ho installato con successo watir per Win7x64 in quel modo prima.
