Windows PowerShell installer fails with "The property 'error' cannot be found on this object"

[ninjin-sirisiri]

Describe the bug

The official Windows install command fails during setup:

irm https://vite.plus/ps1 | iex

It prints:

Setting up VITE+...
Invoke-Expression: The property 'error' cannot be found on this object. Verify that the property exists.

Because this happens while running the documented install command, I could not complete installation.

Reproduction

Not available yet.

Steps to reproduce

1. Open PowerShell on Windows

2. Run:

   irm https://vite.plus/ps1 | iex

3. Observe the installer output

System Info

Please let me know if you want me to provide more detailed environment info.
I can also test a version-pinned install command if that helps narrow it down.

Used Package Manager

npm
