Powershell 脚本运行，但输出错误：“术语“$varArgs”未被识别为 cmdlet、函数、脚本文件或可操作的名称”

如果这是一件非常简单的事情，我很抱歉，但我真的很难理解编码，所以我希望有人能帮助我。我有一个相对简单的 Powershell 脚本。它似乎可以运行，但对于输出，我得到了这个 Stderr 日志消息。如果有人能告诉我如何纠正它，我将不胜感激。

'$varArgs' : The term ''$varArgs'' is not recognized as the name of a cmdlet, function, script file, or operable 
program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

脚本如下：

# If you are reading this, you have copied the Component successfully,
# probably for the purposes of attaching your own configuration file.
# Near the bottom of this page, attach your .bgi file to the Component
# and then save the Component with a new name. The script will identify
# the presence of the file and alter the startup routines to use it.

write-host "Install and configure BGInfo to run on Startup"

    } else {

    }
}

您的脚本语法不正确。

if (!(test-path *.bgi)) {
    write-host "- ERROR: There needs to be at least one .bgi file for the Component to work."
    write-host "  Execution cannot continue. Exiting."
    exit 1
} else {
    if (test-path *.bgi -exclude default.bgi) {
        $varArgs=(ls *.bgi -Exclude default.bgi | Select-Object -First 1).Name
        $varArgs=`'$varArgs`'
    } else {
        $varArgs='default.bgi'
    }
}

应为以下内容：

if (!(test-path *.bgi)) {
    write-host "- ERROR: There needs to be at least one .bgi file for the Component to work."
    write-host "  Execution cannot continue. Exiting."
    exit 1
} else {
    if (test-path *.bgi -exclude default.bgi) {
        $varArgs=(ls *.bgi -Exclude default.bgi | Select-Object -First 1).Name            
    } else {
        $varArgs='default.bgi'
    }
}

通过运行以下命令我能够确定此行为：

$varArgs=(ls *.txt -Exclude "Test.txt" | Select-Object -First 1).Name
Move-Item $varArgs "$env:USERPROFILE\Desktop\New folder"

它将桌面上第一个不是“Test.txt”的 .txt 文件移动到桌面上名为“新文件夹”的文件夹中。
