启用功能在 powershell 控制台中有效，但不适用于脚本

Question

我有一个脚本应该根据提供的列表安装功能。输出很好，但命令总是无法安装，但它们可以在 powershell 控制台中运行。

$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
}

使用启用 windows 可选功能方法我得到这个错误：

Enable-WindowsOptionalFeature : Feature name NetFx4ServerFeatures                                                           
Enabled is unknown.
At C:\features.ps1:12 char:3
+   Enable-WindowsOptionalFeature -Online -FeatureName "$($feature)" -A ...
+   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : NotSpecified: (:) [Enable-WindowsOptionalFeature], COMException
+ FullyQualifiedErrorId : Microsoft.Dism.Commands.EnableWindowsOptionalFeatureCommand

在 powershell 脚本中使用 dism 导致：

Deployment Image Servicing and Management tool
Version: 10.0.16299.15

Image Version: 10.0.16299.125


Error: 87

The enable option is unknown. 
For more information, refer to the help by running DISM.exe /?.

Answer 1

从dism版本来看，我认为Windows10在你的电脑上是运行，所以推荐使用PowerShell。

$features = (Get-WindowsOptionalFeature -Online | ? state -eq 'enabled').FeatureName
foreach($feature in $features) {
     Enable-WindowsOptionalFeature -FeatureName $feature -Online -All -NoRestart
    }

这在测试后对我有用。 :)

Answer 2

问题最终是字符串 $feature 实际上是 "Enabled" 而我无法看到它们在同一行上。

最后，我是这样解决问题的：

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

启用功能在 powershell 控制台中有效，但不适用于脚本

Enable feature works in powershell console but not as script
