VSTS构建:软件包无法恢复 - 无法为".NETStandard,Version = v2.0"解析"NETStandard.Library(> = 1.6.1)"

Question

我越来越

无法为'.NETStandard,Version = v2.0'解析'NETStandard.Library(> = 1.6.1)'.

在我将aspnetcore应用程序升级到netcoreapp2.0我的库并使用之后,使用Hosted2017构建代理构建VSTS netstandard2.0.

在当地工作正常.

我编辑了我的构建定义以使用.net核心构建任务v2.* preview:

不再需要第2步.我把它留在了解决方案中,因为它可能仍然可以帮助一些人.谢谢,@ Liero指出了这一点.

原始答案

我刚刚遇到了这个问题并通过做三件事解决了这个问题:

1. 使用.NET Core SDK(! - not runtime!)版本2.0.0:

2. 使用最新的NuGet feed(4.3.0):

3. 恢复你的包裹:

更新 此处值得一提的是,您应该指定从哪里获取NuGet包.根据屏幕截图(参见小复选框),大多数应用程序可能只使用NuGet.org提要,但您可以在NuGet.config文件中指定自定义提要.在这种情况下,勾选'在NuGet.config中输入',然后指定该文件的路径.

为了说明顺序,这是我的工作队列:

我希望这可以帮助你和其他任何反对这个问题的人.如果您有任何疑问,请告诉我.:)
