nsh의 ssh2 모듈을 가져온 후의 오류

Question

나는 클러스터로 ssh를하고 스파크 코드를 실행해야한다. 이 작업은 브라우저에서 수행해야합니다. Reactjs를 사용하여 UI를 만들고 'ssh2'를 사용하여 NPM에서 클러스터에 액세스합니다. 다음 코드를 사용할 때.

var Client = require('ssh2').Client;

은 내가 follwing을 경고 및 오류 메시지가 표시됩니다.

나는

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

아직도 문제가 동일하게 유지

target: 'node' 

및

을 추가하여 webpack.config.js 파일을 변경했습니다. 이 문제를 어떻게 해결합니까? 클러스터로 ssh 할 수있는 다른 방법이 있습니까?

Answer 1

필요한 프로토콜을 지원하지 않거나 필요한 작업을 수행하지 않는 웹 브라우저에서 ssh로 클러스터에 ssh하려고했습니다. 따라서 백엔드에서하는 것이 좋습니다.
