NuGet：'X'已经为'Y'定义了依赖关系 [英] NuGet: 'X' already has a dependency defined for 'Y'

问题描述

我在尝试安装软件包时遇到以下错误 Microsoft.AspNet.Server.IIS

I am getting the following error in NuGet while trying to install package Microsoft.AspNet.Server.IIS

Attempting to resolve dependency 'Microsoft.AspNet.Loader.IIS.Interop (≥ 1.0.0-alpha4-10330)'.
Attempting to resolve dependency 'Microsoft.AspNet.Loader.IIS (≥ 1.0.0-alpha4-10330)'.
'Microsoft.AspNet.Loader.IIS' already has a dependency defined for 'Microsoft.AspNet.FeatureModel'.

如何解决？

UPDATE：
我还得到以下内容：

UPDATE: Also I am getting the following:

Attempting to resolve dependency 'Microsoft.Framework.DependencyInjection (≥ 1.0.0-alpha4-10326)'.
'Microsoft.Framework.DependencyInjection' already has a dependency defined for 'Microsoft.Framework.ConfigurationModel'.
