Powershell 无法绑定(bind)参数 ForegroundColor

Question

我创建了以下 Powershell 脚本，希望将其用于将文件复制到网络共享。

function Copy-Deploy
{
 param(
  [Parameter(Position=0,Mandatory=$true,HelpMessage="Path to scripts")]
  [Alias("pth")]
  [string]$ScriptPath,

  [Parameter(Position=1,Mandatory=$true,HelpMessage="Deployment script filename")]
  [Alias("dep")]
  [string]$PowershellDeploymentScript,

  [Parameter(Position=2,Mandatory=$true,HelpMessage="MSI filename")]
  [Alias("m")]
  [string]$MSI,

  [Parameter(Position=3,Mandatory=$true,HelpMessage="Filename of the MSBuild script (.btdfproj)")]
  [Alias("msb")]
  [string]$MSBuildScript,

  [Parameter(Position=4,HelpMessage="UNC path to target server folder")]
  [Alias("server")]
  [string]$TargetServerPath

  )

 $ErrorActionPreference="Stop"

 #Step 1 : copy the MSI, .btdfproj script and control powershell script to the remote server
 Write-Host " Going to enter the mis script block"
 $misScript =
 {
    Write-Host " Path+Filename = {0}({1})" -f $ScriptPath, $PowershellDeploymentScript
    Write-Host " Going to copy files" 
    Write-Host " ScriptPath = $ScriptPath"
    Write-Host " PowershellDeploymentScript = $PowershellDeploymentScript"
    Write-Host " MSI = $MSI"
    Write-Host " MSBuildScript = $MSBuildScript"
    Write-Host " TargetServerPath = $TargetServerPath"


    Copy-Item -Path "$ScriptPath" + "$PowershellDeploymentScript" -Destination "$TargetServerPath"
    Copy-Item -Path "$ScriptPath" + "$MSI" -Destination "$TargetServerPath"
    Copy-Item -Path "$ScriptPath" + "$MSBuildScript" -Destination "$TargetServerPath"
 }
 Invoke-Command -scriptblock $misScript

 #Step2 : Execute the powershell script ExecuteBizTalkAppMSI.ps1 remotely on the target server
 #using syntax... invoke-command -computer $MachineName -command { $TargetServerPath + ExecuteBizTalkAppMSI.ps1 }" 

}

我使用以下行从 Powershell ISE 运行此脚本:

Copy-Deploy "C:\Builds\3\x.Int.MIS\SupportBTDF\Sources\x.Int.MIS\Dev\V1.0\Src\Solutions\MIS\x.Int.MIS.Deployment\" "ExecuteBizTalkAppMSI.ps1" "bin\debug\x.Int.MIS-3.0.0.msi" "x.Int.MIS.Deployment.btdfproj" "\\d-vasbiz01\BizTalkDeployment"

然后我收到以下错误:

Cannot bind parameter 'ForegroundColor'. Cannot convert value "C:\Builds\3\x.Int.MIS\SupportBTDF\Sources\x.Int.MIS\Dev\V1.0\Src\Solutions\MIS\x.Int.MIS.Deployment\,ExecuteBizTalkAppMSI.ps1" to type "System.ConsoleColor" due to invalid enumeration values. Specify one of the following enumeration values and try again. The possible enumeration values are "Black, DarkBlue, DarkGreen, DarkCyan, DarkRed, DarkMagenta, DarkYellow, Gray, DarkGray, Blue, Green, Cyan, Red, Magenta, Yellow, White".At C:\Builds\3\x.Int.MIS\SupportBTDF\Sources\x.Int.MIS\Dev\V1.0\Src\Solutions\MIS\x.Int.MIS.Deployment\CopyDeployScriptThenExecute.ps1:79 char:16

谁能告诉我哪里出错了？

Answer 1

该行:

Write-Host " Path+Filename = {0}({1})" -f $ScriptPath, $PowershellDeploymentScript

是问题所在。

像这样写:

Write-Host (" Path+Filename = {0}({1})" -f $ScriptPath, $PowershellDeploymentScript)

-f被视为 -ForegroundColor参数比字符串格式运算符。
