visual-studio-2010 - NuGet升级问题

Question

我有 MVC3 (1.0) 附带的 NuGet 版本，但是当我尝试升级到最新版本(当前为 1.4)时，它失败了，我在日志文件中看到以下内容:

6/27/2011 1:25:08 PM - VSIXInstaller.SignatureMismatchException: The installed version of 'NuGet Package Manager' is signed, but the update version has an invalid signature. Therefore, Extension Manager cannot install the update. at VSIXInstaller.Common.VerifyMatchingExtensionSignatures(IInstalledExtension installedExtension, IInstallableExtension updateExtension) at VSIXInstaller.InstallProgressPage.BeginInstallVSIX(SupportedVSSKU targetAppID)

我什至尝试卸载 NuGet(通过“添加或删除程序”)并手动安装 1.4，但我莫名其妙地收到了相同的消息。知道我做错了什么吗？

Answer 1

1. 关闭所有 Visual Studio 2010 实例。
2. 以管理员身份再次打开 Visual Studio
3. 转至“工具”>“扩展管理器”
4. 卸载 NuGet
5. 再次安装 NuGet。

如果您无法卸载它，请转到:

C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft Corporation\NuGet 包管理器

并删除该文件夹。删除此内容的风险由您自行承担!
