dxc.exe works in cmd but not works in Windows PowerShell

Description
I'm compile the same shader using dxc.exe.
It succeed in cmd but failed in Windows PowerShell.
I'm not sure, is this a problem?

Steps to Reproduce
Download latest Pre-built Releases of DXC.
Copy shader from https://github.com/microsoft/DirectX-Graphics-Samples/blob/master/Samples/UWP/D3D12SM6WaveIntrinsics/src/wave.hlsl to local.

Open windows terminal (Windows PowerShell) or cmd and goto the folder where the shader is.
Run the compile cmd:
dxc /Zi /E"VSMain" /Vn"g_Wave_VS" /Tvs_6_0 /Fh"wave_vs.hlsl.h" /nologo wave.hlsl

Actual Behavior

In Command Prompt, it shows:

D:\Share\Tools\DXCompiler\bin\x64>dxc /Zi /E"VSMain" /Vn"g_Wave_VS" /Tvs_6_0 /Fh"wave_vs.hlsl.h" /nologo wave.hlsl
warning: no output provided for debug - embedding PDB in shader container.  Use -Qembed_debug to silence this warning.

And it generate the output file wave_vs.hlsl.h

But in Windows PowerShell, it shows:

PS D:\Share\Tools\DXCompiler\bin\x64> dxc /Zi /E"VSMain" /Vn"g_Wave_VS" /Tvs_6_0 /Fh"wave_vs.hlsl.h" /nologo wave.hlsl
warning: no output provided for debug - embedding PDB in shader container.  Use -Qembed_debug to silence this warning.
error: validation errors
error: Container part 'Program Input Signature' does not match expected for module.
error: Container part 'Program Output Signature' does not match expected for module.
Validation failed.

And no output is generated.

I just found that dxc --version doesn't works in Windows PowerShell, but dxc --help works.

Environment

• DXC version: dxcompiler.dll: 1.7 - 1.7.2308.7 (69e54e290); dxil.dll: 1.7(101.7.2308.12)
• Host Operating System: Microsoft Windows [Version 10.0.19045.3930]

Powershell doesn't include your local directory in the execution path by default. You might be finding a different dxc than you think you are. Try where dxc to find out which it's using.

Thanks a lot, use .\dxc.exe instead in power shell works.

I have an old version dxc installed:
In power shell:

PS D:\Share\Tools\DXCompiler\bin\x64> (get-command dxc.exe).Path
C:\VulkanSDK\1.2.141.2\Bin\dxc.exe
PS D:\Share\Tools\DXCompiler\bin\x64> (get-command .\dxc.exe).Path
D:\Share\Tools\DXCompiler\bin\x64\dxc.exe

In command prompt:

D:\Share\Tools\DXCompiler\bin\x64> where dxc.exe
D:\Share\Tools\DXCompiler\bin\x64\dxc.exe
C:\VulkanSDK\1.2.141.2\Bin\dxc.exe
