In order to solve the ‘Validate Class not Found from Baseame’ in Magento 2, you need to open the Loader.php file from vendor/magento/zendframework1/library/Zend/ and update the code as f0llowing:

public static function isReadable($filename)
{
    if (is_readable($filename)) {
        // Return early if the filename is readable without needing the
        // include_path
        return true;
    }

    if (strtoupper(substr(PHP_OS, 0, 3)) == 'WIN'
        && preg_match('/^[a-z]:/i', $filename)
    ) {
        // If on windows, and path provided is clearly an absolute path,
        // return false immediately
        return false;
    }

    foreach (self::explodeIncludePath() as $path) {
        if ($path == '.') {
            if (self::is_readable2($filename)) {
                return true;
            }
            continue;
        }
        $file = $path . '/' . $filename;
        if (self::is_readable2($file)) {
            return true;
        }
    }
    return false;
}

private static function is_readable2($filename) {
    try {
        return is_readable($filename);
    } catch (Exception $ex) {
        return false;
    }
}
