使用 Microsoft.PowerShell.Commands 找不到命名空间“CopyItemCommand”

Posted 2023-03-27

【中文标题】使用 Microsoft.PowerShell.Commands 找不到命名空间“CopyItemCommand”

【英文标题】：namespace 'CopyItemCommand' could not be found, using Microsoft.PowerShell.Commands

【发布时间】：2022-01-11 16:59:09

【问题描述】：

根据我的任务，我一直在构建一个名为 CoApp 的旧库，我使用的是 Visual Studio 2013，我不得不对 NuGet 版本和引用路径进行一些小的更改，例如“System.Management.Automation”和到目前为止，我在成功构建 20 个解决方案中的 17 个方面取得了很大进展，我只剩下一个错误“找不到命名空间‘CopyItemCommand’”，这阻止了最后 3 个项目的构建，我正在努力寻找原因。我认为 Visual Studio 正在查找引用，因为“CopyItemCommand”的下划线是绿色而不是红色，当我将鼠标悬停在它上面时它会显示正确的命名空间？

出现错误的项目使用路径“C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\Microsoft.PowerShell.Commands.Management\v4 引用了“Microsoft.PowerShell.Commands.Management” .0_3.0.0.0__31bf3856ad364e35\Microsoft.PowerShell.Commands.Management.dll”，从我有限的理解来看，这个错误是因为项目引用了错误的版本或“Microsoft.PowerShell.Commands.Management”，就像'System.Management.Automation' 的案例，但是我没有找到任何有用的信息来说明要使用的正确版本以及在哪里可以找到它。

请问有谁知道我可以尝试解决这个错误吗？

【参考方案1】：

我已修复错误，Microsoft.PowerShell.Commands.dll 依赖于相同版本的 System.Management.Automation.dll。将 Microsoft.PowerShell.Commands.dll 更改为相同版本“1.0.0.0__31bf3856ad364e35”后，我现在可以编译代码了。
