Question

我有一个从PowerShell运行的NPM命令：

npm install process-migrator -g 
process-migrator

此命令在配置不正确时会返回错误，但是我无法在PowerShell中进行接缝。

[ERROR] [2018-09-25T15:30:30.610Z] Cannot find configuration file 'configuration.json'
[INFORMATION] [2018-09-25T15:30:30.615Z] Generated configuration file as 'configuration.json', please fill in required information and retry.

是否可以通过某种方式获取错误？

我尝试过：

if($?) {            
   Write-Host "Process-Migrator completed sucessfully." $LASTEXITCODE           
} else {   
   Write-VstsTaskError "Process-Migrator FAILED " $LASTEXITCODE -ErrCode $LASTEXITCODE
} 
Process-Migrator completed sucessfully. 1

但是$？返回true，$ LASTEXITCODE为1。

Answer 1

您将需要捕获应用程序 first 的输出：

$output = & 'process-migrator.exe' 2>&1
if ($LASTEXITCODE -ne 0)
{
    $err = $output.Where{$PSItem -match 'ERROR'}
    Write-VstsTaskError "Process-Migrator FAILED: $err" -ErrCode $LASTEXITCODE
}

注意：我对扩展进行了假设，以使执行更加细化
