Enable feature works in powershell console but not as script

I have a script that is supposed to install features based on a list provided. The out is fine, but the commands always fail to install but they work in the powershell console. 

$features_to_enable=New-Object 
System.Collections.Generic.List[System.Object]

# We only want to read the features that are enabled. 
Get-Content 'C:\features.txt' | Where-Object {$_ -match ".*Enabled"} | 
ForEach-Object {
  $features_to_enable.Add($_)
}

# Converted List to Array
$features_to_enable.ToArray()

forEach($feature in $features_to_enable) {
  #Enable-WindowsOptionalFeature -Online -FeatureName "$($feature)" -All -NoRestart
  dism /Online /Enable /FeatureName:"$($feature)" /All
}

Using the enable windows optional feature method I get this error:

Enable-WindowsOptionalFeature : Feature name NetFx4ServerFeatures                                                           
Enabled is unknown.

Using dism within the powershell script leads:

The enable option is unknown.

Solution

  • The problem ended up being that the string $feature actually is "Enabled" and I wasn't able to see that they were on the same line.

    In the end, I solved the problem by doing this:

    $f = $feature.replace(' ' , '').replace('Enabled', '')
Enable-WindowsOptionalFeature -Online -FeatureName $f -All -NoRestart
