.net - 如何修复 Visual Studio 2015 中的 DNX/DNVM？

Question

今天我在 Windows 7 x64 上安装了 VS 2015。主要是为了测试新的 .Net Core 功能等。为了测试，我创建了新的 C#“控制台应用程序(包)”解决方案并收到以下消息:

DNX SDK version 'dnx-clr-win-x86.1.0.0-beta5' failed to install. The solution will use DNX SDK version ‘dnx-clr-win-x86.1.0.0-beta5’ for this session.

我无法编译和调试项目。另外，当我在项目属性中打开调试选项卡时，VS 崩溃了。

打开解决方案时 DNVM 输出:

Invoke-Command : The term 'x86' is not recognized as the name of a cmdlet, func
tion, script file, or operable program. Check the spelling of the name, or if a
 path was included, verify that the path is correct and try again.

有什么解决办法吗？

另外，我之前已经分别安装了 VS 2015 Preview 和 DNX/DNVM。但我想，我在安装VS 2015之前完全删除了它。这会以某种方式影响当前的 VS 安装吗？

Answer 1

这是一个known issue .

ASP.NET 5: On Windows 7 SP1, DNX SDK cannot be installed without Powershell 3.0.

症状

当您创建 ASP.NET 5 项目时，您会收到以下错误消息:

DNX SDK version 'dnx-clr-win-x86.1.0.0-beta5' failed to install. The solution will use DNX SDK version 'dnx-clr-win-x86-1.0.0-beta5' for this session

解决方法

要解决此问题，请安装 Windows Powershell 3.0(或更高版本)并尝试再次创建项目。要查看当前的 PS 版本，请运行 $PsVersionTable 命令 ( details )。
