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

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

取消阻止內(nèi)容。這是有關(guān)該問題的詳細(xì)說明的指南，但實(shí)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(xiàng)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(yùn)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?yàn)槟坪踔恍枰獔?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(cuò)誤的另一種體驗(yàn)是當(dāng)Powershell與程序集沒有.NET運(yùn)行時(shí)版本時(shí)。2.0運(yùn)行.NET 2運(yùn)行時(shí)，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(yùn)行時(shí)。

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(dāng)我嘗試加載其中一個(gè)dll時(shí)，出現(xiàn)錯(cuò)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(shí)遇到的錯(cuò)誤。
