NuGet 包管理器:“AutoMapper"已经为“Microsoft.CSharp"定义了依赖项

NuGet Package Manager: #39;AutoMapper#39; already has a dependency defined for #39;Microsoft.CSharp#39;(NuGet 包管理器:“AutoMapper已经为“Microsoft.CSharp定义了依赖项)

问题描述

我正在尝试将 AutoMapper 作为依赖项添加到在 Visual Studio Premium 2012 上使用 NuGet 的项目，但它失败了.

I'm trying to add AutoMapper as a dependency to a project using NuGet on Visual Studio Premium 2012, but it fails.

上面写着:

操作失败
'AutoMapper' 已经定义了一个依赖项'Microsoft.CSharp'.

Operation failed
'AutoMapper' already has a dependency defined for 'Microsoft.CSharp'.

我可以添加其他依赖项.

I'm able to add other dependencies.

我正在使用 VS 2012 的最新版本的包管理器:

I'm using the last version of the package manager for VS 2012:

NuGet 包管理器 2.8.60318.667

NuGet Package Manager 2.8.60318.667

我应该检查什么?

推荐答案

好像是automapper当前版本的问题:

Seems to be a problem with the current version of automapper:

AutoMapper 5.0.0 2016 年 6 月 28 日，星期二

AutoMapper 5.0.0 Tuesday, June 28, 2016

我尝试了以前的版本，它可以工作:

I tried with the previous version and it works:

PM> Install-Package AutoMapper -Verbose
Install-Package : 'AutoMapper' already has a dependency defined for 'Microsoft.CSharp'.
At line:1 char:16
+ Install-Package <<<<  AutoMapper -Verbose
    + CategoryInfo          : NotSpecified: (:) [Install-Package], InvalidOperationException
    + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand

PM> Install-Package AutoMapper -Version 4.2.1
Installing 'AutoMapper 4.2.1'.
Successfully installed 'AutoMapper 4.2.1'.

所以，如果不能更新 NuGet 包管理器，答案是:

So, if you can't update NuGet Package Manager, the answer is:

PM> Install-Package AutoMapper -Version 4.2.1
