vs2017 - 无法安装nuget包：Microsoft.Extensions.Identity.Stores -Version 2.0.0 [英] vs2017 - cant install nuget package: Microsoft.Extensions.Identity.Stores -Version 2.0.0

问题描述

尝试按照编译错误将以下nuget pkg安装到我的asp.net core 2.0库，告诉我安装它，但只是得到后面的错误。我从nuget.org复制了以下行：

Install-Package Microsoft.Extensions.Identity.Stores -Version 2.0.0

Install-Package ：无法找到"Microsoft.Extensions.Identity.Stores"软件包的版本"2.0.0"。在行：1 char：1 + Install-Package Microsoft.Extensions.Identity.Stores -Version 2.0.0 + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo：NotSpecified： （:) [Install-Package]，Exception + FullyQualifiedErrorId：NuGetCmdletUnhandledException，NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand

如果我使用'Manage nuget pkgs for solution'浏览nuget pkgs我可以看到很多启动Microsoft.Extensions的pkgs，但Microsoft.Extensions.Identity.Stores不是其中之一。

解决方案

你好Alex，

欢迎来到MSDN论坛。

参考你的描述，我试图创建asp.net core 2.0类库和web应用程序，然后使用命令或'经理Nuget包
解决方案...'来安装此扩展：Microsoft.Extensions.Identity.Stores -Version 2.0.0
它可以正常工作如下：

>>如果我使用'Manage nuget pkgs for solution'浏览nuget pkgs我可以看到很多pkgs启动了Microsoft.Extensions但是Microsoft.Extensions.Identity.Stores
不是其中一个。

请检查以下内容：

1. 检查上面屏幕截图中的包源，它应该选择'nuget.org'或'全'
2. 单击Package源旁边的设置图标，确保选中'nuget.org'选项，源链接为'https://api.nuget.org/v3/index.json'

如果此问题仍然存在，请在此处共享C：\ Users \ user name \ AppData \Roaming\NuGet下的文件'NuGet.Config'，感谢您的合作。

祝你好运，

萨拉

Trying to install the following nuget pkg to my asp.net core 2.0 library per a compile err that tells me to install it, but just get the error that follows. I copied the following line from nuget.org:

Install-Package Microsoft.Extensions.Identity.Stores -Version 2.0.0

Install-Package : Unable to find version '2.0.0' of package 'Microsoft.Extensions.Identity.Stores'. At line:1 char:1 + Install-Package Microsoft.Extensions.Identity.Stores -Version 2.0.0 + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Install-Package], Exception + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand

If I browse nuget pkgs using 'Manage nuget pkgs for solution' I can see lots of pkgs that start w Microsoft.Extensions but Microsoft.Extensions.Identity.Stores is not one of them.

解决方案

Hi Alex,

Welcome to the MSDN forum.

Refer to your description, I tried to create asp.net core 2.0 class library and web application, then used the command or the ‘Manager Nuget Packages for Solution…’ to install this extension: Microsoft.Extensions.Identity.Stores -Version 2.0.0 and it works fine as below:

>> If I browse nuget pkgs using 'Manage nuget pkgs for solution' I can see lots of pkgs that start w Microsoft.Extensions but Microsoft.Extensions.Identity.Stores is not one of them.

Please check the following:

1. Check the Package source in the above screenshot, it should select the ‘nuget.org’ or ‘All’
2. Click the setting icon beside the Package source, make sure the option ‘nuget.org’ is checked and the source link is ‘https://api.nuget.org/v3/index.json’

If this issue persists, please share the file ‘NuGet.Config’ under C:\Users\user name\AppData\Roaming\NuGet in here, thank you for your cooperation.

Best regards,

Sara
