Postsharp安装错误

Question

我正在尝试安装postsharp express 4.1，但安装失败，并出现错误"Proxy Authentication Required“。

我的机器上同时安装了Visual studio 2012和2015。下面是postsharp日志文件中的跟踪。任何建议都会有所帮助。

 PostSharp.HQ.v3.0.exe Information: 0 : Registry key HKCU\Software\Microsoft\VisualStudio\14.0\ExtensionManager\EnabledExtensions does not exist.

Answer 1

NuGet包管理器扩展是PostSharp Tools for Visual Studio的基本组件，因此安装程序会尝试从Visual Studio Gallery下载NuGet包管理器扩展，如果它未安装或不满足最低版本要求(用于VS2012和VS2013的NuGet 2.2和用于VS2015的NuGet 3.0 )。

在这种情况下，需要代理身份验证，而PostSharp不能很好地处理这种情况。

作为解决方法，您可以手动安装NuGet包管理器扩展。在这种情况下，安装程序不应该尝试访问Visual Studio Gallery，并且不应该抛出WebException。
