我需要从本地工件下载包。在大多数服务器上它都有效。在我的所有服务器上，我已经像这样注册了我的包源：
Register-PackageSource -name artifactory -source <url> -credential $cred
这显示为已注册的包源。之后我可以安装软件包。但是，当我这样做时，在一台服务器上
find-package -source artifactory -cedential $cred
我明白了
warning: Unable to resolve package source.
当我使用 nuget.exe 从有问题的服务器上的同一源下载软件包时，它可以正常工作。
Find-Package 的完整调试如下所示：
