How to debug install.ps1 script of NuGet package

Question

So we can include an install/uninstall powershell scripts in a NuGet package. I tried, but my install.ps1 does not work. Is there any possibility to find out why? Debugging,

Answer 1

You might call Start-Transcript at the beginning of install script and Stop-Transcript at the end. You would probably wrap the install code like this:

try {
  $ErrorActionPreference = 'stop'  # stop on error
  Start-Transcript c:\a.txt
  ...
}
catch {
  write-host $_
}
finally {
  Stop-Transcript
}

Also $ErrorActionPreference = 'inquire' (instead of stop) could possibly work. However, no chance to try it now. See http://tasteofpowershell.blogspot.com/2008/07/handling-errors-in-powershell.html
