Question

我正在尝试安装postharp express 4.1，但安装失败，并显示“需要代理身份验证”错误。

我的计算机上安装了Visual Studio 2012和2015。以下是postsharp日志文件中的跟踪。任何建议都会有所帮助。

Answer 1

NuGet Package Manager扩展是Visual Studio的PostSharp工具的基本组件，因此安装程序会尝试从Visual Studio库下载NuGet Package Manager扩展（如果未安装或不符合最低版本要求）（NuGet 2.2 for VS2012和VS2013以及VS2015的NuGet 3.0。）

在这种情况下，需要代理身份验证，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 Package Manager扩展。在这种情况下，安装程序不应尝试访问Visual Studio库，并且不应抛出WebException。
