Answer 1

您还需要包含 Crypt_RSA 类的 RSA.php 文件。

在你的其他包含下面添加这个（假设你已经下载了这个文件）：

include('library/php/Crypt/RSA.php');

Answer 2

添加 Ryan Kempt 所说的内容，确保您的 include_path 设置正确。例如。

<?php
set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib');

include('Net/SSH2.php');

Answer 3

您可以使用 pear 安装 phpseclib 或从站点获取它们

http://phpseclib.sourceforge.net/pear.htm

手动下载您想要的每个类并将它们包含在您的主项目中。
