我刚刚在我的 PC 上安装了 Windows 8 并下载了适用于 Windows 8 的 Microsoft Visual Studio Express 2012.已更新和所有内容，当我尝试通过包管理器控制台安装任何东西时，我收到以下错误:

I just installed Windows 8 on my PC and downloaded Microsoft Visual Studio Express 2012 for Windows 8. Updated and everything, and when I try to install anything thru Package Manager Console, I get following error:

PM> Install-Package Parse Attempting to resolve dependency 'Newtonsoft.Json (≥ 4.5.9)'. Successfully installed 'Newtonsoft.Json 4.5.11'. Successfully installed 'parse 1.0.5'. Successfully uninstalled 'Newtonsoft.Json 4.5.11'. Install failed. Rolling back... Install-Package : Failed to add reference to 'Newtonsoft.Json'. At line:1 char:1 + Install-Package Parse + ~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Install-Package], InvalidOperationException + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand

有谁知道如何解决这个错误?

Does anyone know how to fix this error?

推荐答案

检查您是否已经在 packages.config 中添加了 Newtonsoft.Json 引用.如果是，请删除 Newtonsoft.Json 条目并重试 Install-Package.

Check if you already have Newtonsoft.Json reference added in packages.config. If yes, delete Newtonsoft.Json entry and retry Install-Package.
