推荐答案

如果你从互联网上下载了.DLLs，Powershell默认不会信任他们，你可以在这里做两件事：

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

1. 取消屏蔽内容，这是一个有关问题的一些细节的指导，但本质上你只需右键单击下载的文件，选择属性，然后在常规选项卡中单击解除阻止。您可以使用 Unblock-File cmdlet直接从powershell中解除封锁。


2. 更改您的执行政策。这也可以允许您下载的恶意脚本运行，因此要谨慎。

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.

具体查看和解除封锁您信任的内容似乎更好的路由，特别是对于你的情况，因为你似乎只会这样做一次，你信任的包。

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.

编辑：如果没有解决这个问题，我遇到这种类型的错误的另一个经验是Powershell与程序集不同的.NET运行时版本。对于某些上下文，请参阅此问题，其中Powershell 2.0运行.NET 2运行时，asker需要.NET 4用于某些程序集。

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.

您没有使用相同版本的PS，因此您的里程可能会有所不同，但我会尝试创建/编辑每个链接的答案的配置文件，以支持您正在使用的DLL。

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.
