error running build_mapnik.bat: 'powershell' is not recognized as an internal or external command

[springmeyer]

@BergWerkGIS - any ideas what I need to do to avoid the "powershell" not found error? this is on my aws machine I've been using for several months. I ran settings.bat, then build_mapnik.bat, then hit this.

looks like its set PATH=C:\Windows\System32\WindowsPowershell\v1.0\;%PATH%

Strange. It should already be on %PATH% on recent OSes. I suppose you are using 2012?

Did you change any Windows features? While researching this, I found out, that PowerShell can suddenly disappear when doing so.

For later reference:

• check if C:\Windows\System32\WindowsPowershell\v1.0 exists
  • if directory does not exist or is empty , enable Powershell: like so

dism.exe /online /enable-feature /featurename:MicrosoftWindowsPowerShellRoot
dism.exe /online /enable-feature /featurename:MicrosoftWindowsPowerShell /all

• check if Powershell is available via where powershell
  • if it's not available add its directory to PATH:

set PATH=C:\Windows\System32\WindowsPowershell\v1.0;%PATH%

I'm now hitting broken/missing PATH to powershell on my AWS win ec2 when I run settings.bat. Going to add the path in there now to avoid having to re-find this ticket.
