我在 Visual Studio 2010 中安装包时遇到问题。当我运行包管理器控制台时,它显示以下错误:
PM> Install-Package wpf.themes
Install-Package : The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
At line:1 char:16
+ Install-Package <<<< wpf.themes
+ CategoryInfo : NotSpecified: (:) [Install-Package], WebException
+ FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand
我该如何解决?
