"Implement me. Unknown stdin file type!" error thrown when running headless process in win32

  • Version: 6.10.0
  • Platform: Windows 7 x86
  • Subsystem:

Hi there - I encountered this while attempting to run PostCSS commands via the PostCSS-CLI command line implementation.

Note - I have only encountered this error in Windows 7. Windows 10 seems to work fine.

The exact error is as shown:

internal/process/stdio.js:82

        throw new Error('Implement me. Unknown stdin file type!');
        ^
    Error: Implement me. Unknown stdin file type!

I found a similar issue in Angular here: angular/angular-cli#4870

They solved it like this:

Let me know if you need more information - I am very new to Node so you might need to simplify any questions you have for me.
