推荐答案

如果您从 Internet 下载了 .DLL，默认情况下 Powershell 将不信任它们.您可以在此处执行以下两项操作之一:

If you downloaded the .DLLs from the internet, Powershell by default will not trust them. You can do one of two things here:

1. 取消阻止内容.这是一个 详细说明问题的指南，但基本上您只需要右键单击下载的文件，选择属性，然后单击常规选项卡中的取消阻止".您可以使用 Unblock-File cmdlet 直接从 Powershell 取消阻止内容.
2. 更改您的执行政策.这也可能允许您下载的恶意脚本运行，所以要小心.

1. Unblock the content. Here's a guide with some elaboration on the problem, but essentially you just need to right-click on the downloaded file, select Properties, and click 'Unblock' in the general tab. You can unblock content directly from powershell by using the Unblock-File cmdlet.
2. Change your execution policy. This can also allow malicious scripts that you download to run, so be cautious.

专门审查和取消阻止您信任的内容似乎是更好的途径，尤其是对于您的情况，因为您似乎只会执行一次并且您信任该程序包.

Specifically reviewing and unblocking content you trust seems the better route, especially for your case since you seem like you would only be doing this once and you trust the package.

如果这不能解决这个问题，那么我遇到的另一个此类错误的经验是 Powershell 与程序集的 .NET 运行时版本不同.有关某些上下文，请参阅此问题，其中 Powershell 2.0 运行 .NET 2 运行时，并且请求者需要 .NET 4 以获取某些程序集.

If that didn't solve that, the other experience I've had with this type of error is when Powershell didn't the same version of the .NET runtime as the assembly. See this question for some context, where Powershell 2.0 ran the .NET 2 runtime and the asker needed .NET 4 for some assemblies.

您使用的不是相同版本的 PS，因此您的里程可能会有所不同，但我会尝试根据链接的答案创建/编辑配置文件，以支持您正在使用的 DLL 的运行时.

You're not using the same version of PS so your mileage may vary, but I would try creating/editing a config file per the linked answer to support the runtime of the DLLs you are using.
