ASP.NET 5：错误的NuGet包类库包

问题描述：

我开始用VS2015社区版和ASP.NET 5.ASP.NET 5：错误的NuGet包类库包

我添加了一个新的类库（包）作为一个新的项目到我的解决办法玩但我无法在其中安装NuGet软件包。恢复后，我有一个“参考（错误 - 请参阅错误列表）”。

如果我将一个基本的Library Class（.dll）作为新项目添加到我的解决方案中，并尝试安装相同的NuGet软件包，它可以像以前一样精美地运行。

也许，我误解这个新的类库包是如何工作的，我试图滥用它......

感谢您的帮助。

请问您可以分享一下project.json文件吗？ –

右键点击引用并选择恢复包。输出窗口中显示了什么？ – firste

我有同样的问题，并通过从命令行运行''''dnu restore'''来解决它。 – ahz

答

要确定你安装了t他为Visual studio提供最新工具。你的project.json似乎是错的。

在visual studio中检查您的nuget feed中是否有无效的Feed，并删除这些源。

检查活动DNX（*）

随着tools->nuget package manager-package manager for solution *选择包源和测试，如果一个软件包源给出任何错误 *找出其中的NuGet养活你的包是可用

在DNU输出那里的端部是使用哪些配置和提要列表

使用dnu restore -?来查找问题的根源。

试试这个 dnu restore --no-cache --packages .\packages1

尝试包。json like this

{ 
    "version": "1.0.0-*", 
    "description": "ClassLibrary3 Class Library", 
    "authors": [ "Thom" ], 
    "tags": [ "" ], 
    "projectUrl": "", 
    "licenseUrl": "", 
    "dependencies": { 

    "EntityFramework": "6.1.3" 
    }, 
    "frameworks": { 
     "dnx451": { }, 
    } 
}

谢谢@ thom-kiesewetter指向我的工具页面。我按照你的指示，我有beta8 x86默认情况下，尝试了dnu恢复（dnu恢复 - 无缓存 - 包装。\ EntityFramework），但仍然得到这个错误： GET https://www.nuget.org/api/v2/FindPackagesById（）？id ='EntityFramework' 错误：FindPackagesById：EntityFramework 发送请求时发生错误。我也用我的新beta8 project.json和提要编辑了我的帖子。它可能是这些讨论中定义的代理问题：https://github.com/aspnet/dnx/issues/451 – sylvain77

答

这似乎是一个代理问题，给我这个No connection could be made because the target machine actively refused it 127.0.0.1:8888错误。

使用Fiddler跟踪它，我发现在打开Fiddler之后，恢复过程和添加新的Nuget包工作正常。与此帖子Why calling API in ASP.NET works only if I have Fiddler open?或此处非常相似的情况：http://www.telerik.com/blogs/help!-running-fiddler-fixes-my-app-。

我也尝试创建一个dnx.exe.config到C:\Users\sylvainc\.dnx\runtimes\dnx-clr-win-x86.1.0.0-beta8\bin,http://github.com/aspnet/dnx/issues/451建议。不幸的是，它似乎不适用于beta8版本。

我的第一个解决方法是使用HTTP协议访问我的NuGet包，如下所示：。

我最终的解决办法是编辑machine.config文件以管理员身份用记事本+在C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config得到提琴手默认的代理定义的平顺性和使用该系统的：

<!--<system.net> 
     <defaultProxy enabled="true" useDefaultCredentials="true"> 
     <proxy autoDetect="false" bypassonlocal="false" proxyaddress="http://127.0.0.1:8888" usesystemdefault="false"/> 
     </defaultProxy> 
    </system.net>--> 
<system.net> 
    <defaultProxy useDefaultCredentials="true" enabled="true"> 
    <proxy usesystemdefault="True"/> 
    </defaultProxy> 
</system.net>

现在ASP.Net的5部作品很好，我甚至有我现在的智能感知正常工作，这是不是这种情况之前与其他代理定义...

感谢

提琴手也是我的原因。 – theguy

就我而言，包源代码指向http://packagesource。修改为https://www.nuget.org/api/v2/修复了probmel
