如果我在我的控制台上运行php artisan tinker，输出是：

[ErrorException]
in_array() expects parameter 2 to be array, string given

如果我运行php artisan tinker--everose，输出是：

额外：
我的Laravel版本是5.1.24。
我刚刚安装了Zizaco/委托
除此之外，应用程序几乎是空白的

编辑：

这是ConfigPath. php中错误的函数：

private static function getDirNames(array $baseDirs) {
    $dirs = array_map(function ($dir) {
        return strtr($dir, '\\', '/') . '/psysh';
    }, $baseDirs);

    // Add ~/.psysh
    if ($home = getenv('HOME')) {
        $dirs[] = strtr($home, '\\', '/') . '/.psysh';
    }

    // Add some Windows specific ones :)
    if (defined('PHP_WINDOWS_VERSION_MAJOR')) {
        if ($appData = getenv('APPDATA')) {
            // AppData gets preference
            array_unshift($dirs, strtr($appData, '\\', '/') . '/PsySH');
        }

        $dir = strtr(getenv('HOMEDRIVE') . '/' . getenv('HOMEPATH'), '\\', '/') . '/.psysh';
        if (!in_array($dirs, $dir)) {
            $dirs[] = $dir;
        }
    }

    return $dirs;
}

如果有人有同样的问题，我是这样解决的：

# add (array) before $dir
if (!in_array($dirs, (array)$dir)) {
    $dirs[] = $dir;
}

提前感谢！
