Sitecore Experience Commerce - SiteUtilityPages path error

When attempting to install Sitecore Experience Commerce 9.0 the following error would appear:

Install-SitecoreConfiguration : Cannot validate argument on parameter 'Source'. The " Test-Path $_ " validation script
for the argument with value

"D:\Projects\MyProject\Install\CommerceDeploy\SIF.Sitecore.Commerce.1.0.1748\-ChildPathSiteUtilityPages" did not
return a result of True. Determine why the validation script failed, and then try the command again.
At D:\Projects\MyProject\Install\CommerceDeploy\SIF.Sitecore.Commerce.1.0.1748\Deploy-Sitecore-Commerce.ps1:70 char:1

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException
    + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Install-SitecoreConfiguration

The problem traces back to the installation PowerShell script and the following line:

SiteUtilitiesSrc = ( Join-Path -Path $DEPLOYMENT_DIRECTORY -ChildPath"SiteUtilityPages" )

There is no space after the -ChildPath which screws up the path in PowerShell, it should be:

SiteUtilitiesSrc = ( Join-Path -Path $DEPLOYMENT_DIRECTORY -ChildPath "SiteUtilityPages" )

The installation will now continue as expected.
