Installation (via gem install) is failing again on Windows 10

Inizia da ext/rugged/extconf.rb, in particolare da run_cmake alla riga 33, e riproduci il problema usando gem install licensee su Windows 10 con l’ambiente Ruby 2.6 mostrato. Controlla il percorso di build dell’estensione nativa e conferma che l’installazione venga completata senza il pgroup ArgumentError segnalato.

Seems the pgroup error--which was fixed recently in #791--is back... 😢

Key line below is:

extconf.rb:33:in `spawn': wrong exec option symbol: pgroup (ArgumentError)
