如果您从互联网上下载.DLL,默认情况下,Powershell将不会信任它们.你可以在这里做两件事之一：

>取消阻止内容.这是一个guide with some elaboration on the problem,但基本上您只需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.
>更改您的execution policy.这也可以允许您下载的恶意脚本运行,因此要小心.

具体来说,查看和取消阻止您信任的内容似乎是更好的选择,特别是对于您的情况,因为您似乎只会这样做一次并且您信任该软件包.

编辑：如果没有解决这个问题,那么我对此类错误的另一种体验是Powershell与.NET程序集的版本不同.有关某些上下文,请参阅this question,其中Powershell 2.0运行.NET 2运行时,而提问者需要.NET 4才能进行某些程序集.

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.
