尝试更新时出现NuGet软件包管理器错误 [英] NuGet Package Manager errors when trying to update

问题描述

今天打开VS2010，扩展管理器通知我NuGet软件包管理器的更新.

Opening VS2010 today, the extension manager notified me of an update for NuGet Package Manager.

在安装过程中，我得到一个安装失败"的信息，并带有查看日志的选项.

During the install, I get an 'Installation Failed' with an option to view the log.

我在该日志文件中看到的关键错误消息是:

The key error message I see in that log file is:

The signature on the update version of 'NuGet Package Manager' does not match 
the signature on the installed version. Therefore, Extension Manager cannot 
install the update.

我要从中升级到的版本号如下.

The version numbers I am upgrading from/to are as follows.

Current Version: 1.5.20902.9026  
New Version: 1.6.21205.9031

在通过此页面关闭VS2010时，我也尝试安装它: 此处

I have also tried to install it while VS2010 is closed via this page: here

推荐答案

更新:最近发布的NuGet 2.0可能还需要先卸载较旧版本的NuGet.

Update: The recently released NuGet 2.0 also may require uninstalling an older version of NuGet first.

摘自NuGet 2.0发行说明:( http://docs.nuget. org/docs/release-notes/nuget-2.0 )

From the NuGet 2.0 Release Notes: (http://docs.nuget.org/docs/release-notes/nuget-2.0)

已知的安装问题

如果运行的是VS 2010 SP1，则如果安装了较旧的版本，则在尝试升级NuGet时可能会遇到安装错误.

If you are running VS 2010 SP1, you might run into an installation error when attempting to upgrade NuGet if you have an older version installed.

解决方法是简单地卸载NuGet，然后从VS Extension Gallery安装它.有关更多信息，请参见 http://support.microsoft.com/kb/2581019 或直接转到VS修补程序.

The workaround is to simply uninstall NuGet and then install it from the VS Extension Gallery. See http://support.microsoft.com/kb/2581019 for more information, or to go directly to the VS hotfix.

注意:如果Visual Studio不允许您卸载扩展(禁用了卸载"按钮)，则可能需要使用以管理员身份运行"来重新启动Visual Studio.

Note: If Visual Studio won't allow you to uninstall the extension (the Uninstall button is disabled), then you likely need to restart Visual Studio using "Run as Administrator."
