Powershell Find-Package失败，无法解析程序包源

Question

我需要从本地artifactory下载包。在大多数服务器上，它都能正常工作。在我的所有服务器上，我注册了我的包源，如下所示：Register-PackageSource -name artifactory -source <url> -credential $cred

这显示为已注册的包源。我可以在之后安装包。但是当我在一台服务器上这样做时

find-package -source artifactory -cedential $cred

我得到了

warning: Unable to resolve package source.

当我使用nuget.exe从有问题的服务器上的相同来源下载包时，它可以正常工作。

Find-Package的完整调试如下所示：

Answer 1

解决方案是：

在此处更新Nuget提供程序程序集后，nuget提供程序的版本为2.8.5.201

C:\Program Files\PackageManagement\ProviderAssemblies\nuget\

还有这里

%localappdata%\PackageManagement\ProviderAssemblies\nuget to

2.8.5.208

一切正常。
