Powershell腳本在調試器中工作，但不在正常運行（ISE）

Question

此腳本（版本1）只在我在ISE中調試時才起作用。但是，如果執行它，它不會刪除oldFilesPath中的文件，以將新路徑從backupPath複製到那裏。我嘗試使用Remove-Item類似管道的其他方法。德爾也不會工作。現在我做了一些實驗並寫了第二個版本（版本2）。我將我的操作放入函數中，並獲得相同的意外行爲。但是，如果我在兩個函數之間暫停60秒，腳本在我的情況下運行良好。所以我認爲PowerShell並不能很好地管理執行或者類似這樣的事情。我不知道。也許你們中的任何人對此有解釋？

Answer 1

你的意思實際上是通過加強與ISE調試器，或只是運行腳本的ISE。如果後者對您嘗試訪問的目錄可能有權限問題。在ISE中運行腳本會使用您的用戶憑證運行它。

Answer 2

即使在調試時，這可能如何工作？你Test-Path命令不應該返回true，因爲

"$oldFilesPath\$_" 

相同

D:\Outlook-Backup\Old-Files\$user\D:\Outlook-Backup\$user\<filename> 

您需要將其更改爲

"$oldFilesPath\$($_.Name)" 

這個工作。與腳本結尾處的"$backupPath\$_"相同。
