问题描述

我安装了PowerShell 3，我需要从Cygwin运行PowerShell 2

但是你看到它仍在运行PowerShell 3。

But as you see it is still running PowerShell 3.

你有什么想法我做错了什么？

Do you have any ideas what am I doing wrong?

如果你好奇为什么我需要从Cygwin运行PowerShell，我写的git钩子。
开发服务器端钩子我写了PowerShell脚本，由于上面描述的问题，我不能用断点的好办法。

If you curious why I need to run PowerShell from Cygwin, it is because of the git hooks I am writing. To develop server-side hooks I write PowerShell script, and because of the problem described above, I cannot use my nice trick with breakpoints

UPD：在Windows 8上使用Cygwin 1.7.11终端

推荐答案

您可能需要提供更多的上下文来查看为什么这不工作。只有我能想到的原因是 -Version 2.0 param没有传递给powershell。

You might have to give more context to see why this is not working. Only reason I can think of is somehow the -Version 2.0 param is not being passed to powershell.
