问题描述

当该确切版本作为 NuGet 发布给官方时，NuGet 的 Install-Package 为何会失败并出现 Unable to find version 'x' of package 'y'存储库，它显示在 .

解决方案

NuGet 目前存在一些与服务问题相关的问题搜索和打包还原功能.这可能是您的包还原失败的原因.

如果其他开发机器工作正常，它们很可能可以访问此软件包的缓存版本.

How it's possible that NuGet's Install-Package fails with Unable to find version 'x' of package 'y' when that exact version is released as NuGet to the official repository and it shown on the https://www.nuget.org/packages/y page.

Here is specific sample with nuget.org content and NuGet Install-Package command output.

UPDATE. Package sources are set to defaults (from nuget.org). Actually, you can see the issue just by running Install-Package Log4Net.Async -Version 1.3.0.

UPDATE 2. I want to highlight that it's not about some developer's machine - the same things happen on Visual Studio Online Hosted Build Controller.

UPDATE 3. Here is how NuGet tries to load package and it looks like NuGet API just broken, because all these requests fail with the error below.

Resource not found for the segment 'Packages'

Also NuGet produces a strange output on NuGet API calls that issued at VS search packages stage, please see here: http://pastebin.com/qveadrZB.

解决方案

NuGet currently has some service issues related to search and package restore functionality. It is possible this is the cause of your package restore failure.

If other dev machines are working OK, it's likely they have access to a cached version of this package.
