Reactjs 导入npm的ssh2模块后出错

我的任务是在集群中执行ssh并执行spark代码。这必须从浏览器中完成。我正在使用Reactjs构建UI，并使用NPM中的“ssh2”访问集群。当我使用以下代码时

var-Client=require（'ssh2'）。客户端；

我收到以下警告和错误消息

我试图通过添加

target: 'node'

及

尽管如此，问题依然存在。如何解决此问题？还有其他方法可以通过ssh连接到集群吗？

我试图通过Web浏览器通过ssh连接到集群，但该浏览器不支持或不让所需的协议执行所需的任务。因此，最好在后端执行

node: {
        console: false,
        fs: 'empty',
        net: 'empty',
        tls: 'empty'
    },
