Error running Install-Module PowerLine

jzabroski commented 6 years ago

Nowhere in the documentation is this gotcha mentioned. Is this on purpose? Can you explain why it would override Write-Host?

PS C:\source\> install-module PowerLine

I have the same issue. However, using the line below as the error suggested, I could install it successfully. Not sure what it is or how safe it is.

 Install-Module PowerLine -AllowClobber

That's true. I forgot about that in PANSIES. PowerLine uses PANSIES for color help...

PANSIES replaces Write-Host with a backwards-compatible version that supports full RGB colors and also works faster... 😀

Getting PANSIES merged into PowerShell Core is on my TODO list, but for now, yes, it's on purpose and safe.

Thanks for updating the documentation to explain PANSIES
