Powershell加载dll错误：Add-Type：无法加载文件或程序集“ WebDriver.dll”或其依赖项之一不支持操作

如何解决Powershell加载dll错误：Add-Type：无法加载文件或程序集“ WebDriver.dll”或其依赖项之一不支持操作

如果从Internet下载.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：

1. 取消阻止内容。这是有关该问题的详细说明的指南，但实际上，您只需要右键单击下载的文件，选择“属性”，然后在常规选项卡中单击“取消阻止”。您可以使用Unblock-Filecmdlet 直接从powershell取消阻止内容。
2. 更改执行策略。这也可能允许您下载的恶意脚本运行，因此要小心。

专门查看和取消阻止您信任的内容似乎是更好的方法，特别是对于您的情况，因为您似乎只需要执行一次并且信任该程序包。

如果那不能解决问题，那么我对这种类型的错误的另一种体验是当Powershell与程序集没有.NET运行时版本时。 2.0运行.NET 2运行时，而问询者需要某些组件的.NET 4。

您没有使用相同版本的PS，因此您的里程可能会有所不同，但是我会尝试根据链接的答案创建/编辑配置文件，以支持所使用的DLL的运行时。

解决方法

我想使用seleniumPowerShell，selenium并从http://www.java2s.com/Code/Jar/s/Downloadseleniumremotedriver2350jar.htm下载selenium。当我尝试加载其中一个dll时，出现错误。希望有人可以帮助我。
