Ich habe versucht, einen Edelstein zu installieren, wie ich es vor der Installation von Yosemite getan habe, aber jetzt erhalte ich eine Fehlermeldung:

/Library/Ruby/Site/2.0.0/rubygems/ext/builder.rb:159:in `synchronize ': FEHLER: Fehler beim Erstellen der nativen Erweiterung des Gems. (Gem :: Ext :: BuildError)

FEHLER: Fehler beim Erstellen der nativen Gem-Erweiterung.

Sackgasse; rekursives Sperren

Dies ist der Befehl, den ich geschrieben habe:

sudo gem install mysql2

Dies ist die Meldung, die im Terminal angezeigt wird:

Ich benutze OSX 10.10 und Xcode 6 Beta.

Hat einer von euch eine Idee, was man dagegen tun kann?
