术语“System.DefaultWorkingDirectory”未被识别为cmdlet的名称

Question

我正在尝试使用PowerShell使用VSTS发布作业生成CSV文件并将其存储到当前工作目录。奇怪的是，之前的代码工作正常。唯一的区别是以前我使用内联脚本，但现在我使用文件路径。

$results = @()

$data = 
@{                       
    uname = $uname             
    upass = "Apple@123"
    uid = $uid    
}

$results += New-Object PSObject -Property $data 

$results | export-csv -Path $(System.DefaultWorkingDirectory)\1UserTestDocument.csv -NoTypeInformation 

write-host "Print all files in the current directory :"
Get-Item *

错误：

[error]术语“System.DefaultWorkingDirectory”未被识别为cmdlet，函数，脚本文件或可操作程序的名称。检查名称的拼写，或者如果包含路径，请验证路径是否正确，然后重试。

你必须使用$env:variable_name_with_underscores_instead_of_dots来检索它。

在你的情况下它：

$env:System_DefaultWorkingDirectory
