Ich versuche, Microsoft.Bcl.Build 1.0.14 zu installieren

Nuget kehrt zurück

Installing 'Microsoft.Bcl.Build 1.0.14'. Successfully installed 'Microsoft.Bcl.Build 1.0.14'. Adding 'Microsoft.Bcl.Build 1.0.14' to LeadTracker.Calendar. Uninstalling 'Microsoft.Bcl.Build 1.0.14'. Successfully uninstalled 'Microsoft.Bcl.Build 1.0.14'. Install failed. Rolling back... An item with the same key has already been added.

Dies passiert auch mit json.net und anderen Paketen.

Ich kann nancy und topshelf aber nicht json.net und bcl hinzufügen.

Ich habe es in VS2012 und 2013 versucht. Ich habe auch versucht, Nuget zu deinstallieren und neu zu installieren. Ich habe auch versucht, das Nuget einer leeren Klassenbibliothek und einer leeren Konsolen-App hinzuzufügen. Der gleiche Fehler wird immer zurückgegeben.

Dies passiert auch mit json.net und anderen Paketen.

Ich habe es auch ohne Paketdatei versucht

Irgendwelche Ideen am meisten geschätzt.

Hier ist der Befehl und Stacktrace
