我的Composer PHP项目卡在require '/vendor/autoload.php'; - My Composer PHP project stucks at require '/vendor/autoload.php';

My Composer PHP project stucks at require '/vendor/autoload.php';

亲爱的StackOverflow社区，

我对Composer很陌生，所以解决方案可能很容易，但我不明白。

我的PHP文件是这样的

<html>
    <head>
        <title>ServerStatusChecker</title>
        <link rel="icon" href="favicon.ico">
    </head>
    <body>
        <?php
        echo "1";
        require '/vendor/autoload.php';
        echo "2";
        use MinecraftServerStatus'MinecraftServerStatus;
        echo "3";
        $response = MinecraftServerStatus::query('mineplex.com', 25565);
        echo "4";
        if (! $response) {
            echo "The Server is offline!";
        } else {
            echo "<img width='"64'" height='"64'" src='"" . $response['favicon'] . "'" /> <br>
                The Server " . $response['hostname'] . " is running on " . $response['version'] . " and is online,
                currently are " . $response['players'] . " players online
                of a maximum of " . $response['max_players'] . ". The motd of the server is '" . $response['description'] . "'.
                The server has a ping of " . $response['ping'] . " milliseconds.";
        }   
        ?>
    </body>
</html>

所以我的问题是，当我调用网页时，它保持空白，除了一个调试1。

我没有得到可见的错误消息或类似的。那么为什么会发生这种情况和/或我做错了什么?

亲切的问候

将第10行require '/vendor/autoload.php';改为require './vendor/autoload.php';，成功了
