我从互联网上获得了以下脚本，当我尝试运行时，它给了我一个错误。

#script
#unzip folder

$shell_app = new-object -com shell.application
$filename = "test.zip"
$zip_file = $shell_app.namespace("C:\temp\$filename")

#set the destination directory for the extracts
$destination = $shell_app.namespace("C:\temp\zipfiles")

#unzip the file
$destination.Copyhere($zip_file.items())

您需要在设置 $destination 变量之前创建“c:\temp\zipfiles”文件夹，这种草率的方式但它会完成这项工作:)

#script
#unzip folder

$shell_app = new-object -com shell.application
$filename = "test.zip"
$zip_file = $shell_app.namespace("C:\temp\$filename")

#set the destination directory for the extracts
if (!(Test-Path "C:\temp\zipfiles\")) { 
    mkdir C:\temp\zipfiles
}
$destination = $shell_app.namespace("C:\temp\zipfiles")

#unzip the file
$destination.Copyhere($zip_file.items())
