在使用Yeoman生成器生成应用程序后运行grunt命令时出现以下错误：

我发现了一个类似的问题（Yeoman grunt could not connect to MongoDB），但我无法在那里找到问题的解决方案。
答案 0 :(得分：0)
这是MEAN.js的旧版本吗？我相信<?php
include "dbconf2.php";
$sqlimage="
SELECT
F.Grafik,
F.knr,
F.brstatus1,
F.untertitel1,
F.anzeigeweb1
FROM FOTO F
WHERE F.knr LIKE 'FHTG20900%'
;";
$stmtimage = sqlsrv_query($connVHS, $sqlimage);
while ($result2=sqlsrv_fetch_array($stmtimage)) {
echo "titel: ".$result2['untertitel1']."<br>";
echo "knr: ".$result2['knr']."<br>";
echo "status: ".$result2['brstatus1']."<br>";
echo "web: ".$result2['anzeigeweb1']."<br>";
echo '<img src="data:image/jpeg;base64,'.base64_encode( $result2['Grafik']).'" style="max-height: 500px; max-width: 400px;"/>'."<br>";
echo "<br>";
}
?>
已被$image = imagecreatefromstring(base64_encode( $result2['Grafik']));
$image = imagescale($image, 100, 100);
ob_start();
imagejpeg($image);
$contents = ob_get_contents();
ob_end_clean();
echo "<img src='data:image/jpeg;base64,".base64_encode($contents)."' />";
imagedestroy($image);
取代，grunt也解决了gulp的问题。
您应该检查自己使用的版本并进行必要的更改。
