ASP.NET 5:类库包中的Nuget包出现错误 [英] ASP.NET 5: Error with Nuget package in Class library Package

本文介绍了ASP.NET 5:类库包中的Nuget包出现错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我开始使用VS2015社区版本和ASP.NET 5.

I start playing with VS2015 community version and ASP.NET 5.

我在解决方案中添加了一个新类库(包)作为新项目，但是无法在其中安装NuGet包.恢复后，我有一个参考(错误-请参阅错误列表)".

I have added a new class library (Package) as a new project into my solution but am unable to install a NuGet package in it. After the restoring, I have a "Reference (Errors - see Error List)".

如果我将基本库类(.dll)作为新项目添加到解决方案中，并尝试安装相同的NuGet程序包，则它的工作方式将像往常一样漂亮.

If i add a basic Library Class (.dll) as a new project into my solution and try to install the same NuGet package, it works beautifully as it used to.

也许，我误会了这个新的类库程序包的工作方式，并且试图滥用它...

Perhaps, I am misunderstanding how this new class library package works and I am trying to misuse it...

感谢您的帮助.

推荐答案

这似乎是一个代理问题，给了我无法建立连接，因为目标计算机主动拒绝了127.0.0.1:8888错误.

It seems to be a proxy issue giving me this No connection could be made because the target machine actively refused it 127.0.0.1:8888 error.

通过Fiddler进行跟踪，我发现在打开Fiddler之后，还原过程和添加新的Nuget包都可以正常工作.这种情况与为什么只有在我打开Fiddler的情况下才能在ASP.NET中调用API?或在以下位置:

Tracking it down with Fiddler, I discovered that after opening Fiddler, the restore process and adding new Nuget packages was working fine. A situation quite similar to this post Why calling API in ASP.NET works only if I have Fiddler open? or here: http://www.telerik.com/blogs/help!-running-fiddler-fixes-my-app-.

我还尝试将dnx.exe.config创建为 C:\ Users \ sylvainc \ .dnx \ runtimes \ dnx-clr-win-x86.1.0.0-beta8 \ bin 在 http://github.com/aspnet/dnx/issues/451 中建议.不幸的是，它似乎不适用于beta8版本.

I also tried to create a dnx.exe.config into C:\Users\sylvainc\.dnx\runtimes\dnx-clr-win-x86.1.0.0-beta8\bin as suggested in http://github.com/aspnet/dnx/issues/451. Unfortunately it seems not to work with the beta8 version.

我的第一个解决方法是按照以下建议使用HTTP协议访问我的NuGet软件包:

My first workaround solution was to use the HTTP protocol to access my NuGet packages as suggested here: Visual Studio 2015 - Can't sign in, Use NuGet, etc. behind corporate proxy.

我的最终解决方案是使用管理员记事本+在 C:\ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ Config 中编辑machine.config文件，以获取提琴手的默认代理定义并使用系统定义:

My final solution was to edit the machine.config file as administrator with Notepad+ in C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config to get ride of the fiddler default proxy definition and to use the system ones:

<!--<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 5可以正常工作，我现在甚至可以使我的intellisense正常工作，而使用其他代理定义则不是这种情况...

Now ASP.Net 5 works fine, I even have my intellisense working properly now which was not the case before with the other proxy definition...

谢谢
