任务计划程序执行 PowerShell 脚本时出现一些错误

Question

我创建了一个具有高权限的任务

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Bypass -File "D:\OneDrive\OneDrive - HAJJAJ\SCRIPTS\01_Hourl_Stock_From_ERP.ps1"

用于将文件从 xls 转换为 xlsx 的脚本 .ps1：

# Set the path to the directory containing the Excel files
$sourceDirectory = "D:\OneDrive\OneDrive - HAJJAJ\FTPData\Stock_From_ERP"

# Set the path to the conversion directory
$conversionDirectory = "D:\ConversionZone"

# Set the path to the destination directory where you want to move the converted files
$destinationDirectory = "D:\OneDrive\OneDrive - HAJJAJ\Production\Stock_From_ERP"

# Set the path to the archive directory
$archiveDirectory = "D:\Archive"

# Set the path to the error log file
$errorLogFilePath = "D:\Logs\ConversionErrorLog_$(Get-Date -Format 'yyyyMMdd_HHmmss').txt"

# Set the new filename
$newFilename = "Stock_From_ERP.xlsx"

# Set the new sheet name
$newSheetName = "Stock_From_ERP_Sheet"

# Get a list of all .xls files in the source directory
$xlsFiles = Get-ChildItem -Path $sourceDirectory -Filter *.xls | Sort-Object CreationTime -Descending | Select-Object -First 1

# Loop through each .xls file
foreach ($file in $xlsFiles) {
    # Construct the full path to the source file
    $sourceFilePath = $file.FullName

    # Construct the full path to the conversion file
    $conversionFilePath = Join-Path -Path $conversionDirectory -ChildPath $newFilename

    try {
        # Create a new Excel Application object
        $excel = New-Object -ComObject Excel.Application

        # Disable alerts and set visible to false to prevent Excel from displaying prompts
        $excel.DisplayAlerts = $false
        $excel.Visible = $true

        # Open the problematic file
        $workbook = $excel.Workbooks.Open($sourceFilePath)

        # Change the sheet name
        $worksheet = $workbook.Worksheets.Item(1)
        $worksheet.Name = $newSheetName

        # Save the workbook as .xlsx format in the conversion directory
        $workbook.SaveAs($conversionFilePath, 51)  # 51 represents the XLSX file format

        # Close the workbook and Excel application
        $workbook.Close()
        $excel.Quit()

        # Release the COM objects
        [System.Runtime.Interopservices.Marshal]::ReleaseComObject($workbook) | Out-Null
        [System.Runtime.Interopservices.Marshal]::ReleaseComObject($excel) | Out-Null
        Remove-Variable excel -ErrorAction SilentlyContinue

        # Copy the converted file to the destination directory with preserving permissions
        Copy-Item -Path $conversionFilePath -Destination $destinationDirectory -Force

        # Remove the original file
        Remove-Item -Path $sourceFilePath -Force

        # Add a waiting time of 5 seconds before moving the source file to the archive directory
        Start-Sleep -Seconds 50

        # Move the source file to the archive directory
        Move-Item -Path $conversionFilePath -Destination $archiveDirectory -Force
    } catch {
        # Log the error to the error log file
        $_.Exception.Message | Out-File -FilePath $errorLogFilePath -Append

        Write-Host "Error processing $($file.Name): $_"
        continue  # Skip processing this file and continue with the next one
    }
}

Write-Host "Conversion and move complete."

当我在正常模式下运行此 .bat 文件（即使以管理员身份运行）时，它会毫无问题地执行代码，但是当我使用任务计划程序运行它时，出现以下错误：

Microsoft Excel 无法访问文件“D:\OneDrive\OneDrive - HAJJAJ\FTPData\Stock_From_ERP\INVIRSIQNZ_528800221_1.xls”。可能的原因有以下几种：

• 文件名或路径不存在。• 另一个程序正在使用该文件。• 您尝试保存的工作簿与当前打开的工作簿同名。
