如何解決Powershell加載dll錯誤：Add-Type：無法加載文件或程序集“ WebDriver.dll”或其依賴項之一。不支持操作？

如果從Internet下載.DLL，默認情況下Powershell將不信任它們。您可以在此處執(zhí)行以下兩項操作之一：

取消阻止內(nèi)容。這是有關(guān)該問題的詳細說明的指南，但實際上，您只需要右鍵單擊下載的文件，選擇“屬性”，然后在常規(guī)選項卡中單擊“取消阻止”。您可以使用Unblock-Filecmdlet 直接從powershell取消阻止內(nèi)容。更改執(zhí)行策略。這也可能允許您下載的惡意腳本運行，因此要小心。

專門查看和取消阻止您信任的內(nèi)容似乎是更好的方法，特別是對于您的情況，因為您似乎只需要執(zhí)行一次并且信任該程序包。

如果那不能解決問題，那么我對這種類型的錯誤的另一種體驗是當Powershell與程序集沒有.NET運行時版本時。2.0運行.NET 2運行時，而問詢者需要某些組件的.NET 4。

您沒有使用相同版本的PS，因此您的里程可能會有所不同，但是我會嘗試根據(jù)鏈接的答案創(chuàng)建/編輯配置文件，以支持所使用的DLL的運行時。

解決方法

我想使用seleniumPowerShell，selenium并從http://www.java2s.com/Code/Jar/s/Downloadseleniumremotedriver2350jar.htm下載selenium。當我嘗試加載其中一個dll時，出現(xiàn)錯誤。希望有人可以幫助我。

這是我的系統(tǒng)信息。

OS Name: Microsoft Windows 7 EnterpriseOS Version:6.1.7601 Service Pack 1 Build 7601OS Manufacturer: Microsoft Corporation

這是我的PowerShell信息。

這是我嘗試加載dll時遇到的錯誤。
