node.js - Angular 6 中的 socket.io-stream 导入问题

Question

我正在使用npm install socket.io-stream 我在我的 Angular 组件上实现了 socket.io-stream ，如下所示:

import * as io from 'socket.io-client';
import * as ss from 'socket.io-stream';

我只想创建一个像这样的双工流:

stream=ss.createStream();

运行 ng build 时出现此错误:

ERROR in ./node_modules/socket.io-stream/lib/iostream.js
Module not found: Error: Can't resolve 'stream' in ' 
'C:\Users\geoffroy\Documents\Mines Alès\2A\Stage\WebService based 
GUI\WebApp\node_modules\socket.io-stream\lib'
ERROR in ./node_modules/socket.io-stream/lib/blob-read-stream.js
Module not found: Error: Can't resolve 'stream' in 
'C:\Users\geoffroy\Documents\Mines Alès\2A\Stage\WebService based 
GUI\WebApp\node_modules\socket.io-stream\lib'

我不明白，因为在我的 server.js 上它似乎可以工作..

我尝试运行命令 npm install stream 并且 ng build 没有出现错误。但是当我启动我的应用程序时，我的浏览器控制台中出现了一个新错误:

inherits_browser.js:5 Uncaught TypeError: Cannot read property 'prototype' of undefined
at Object.inherits (inherits_browser.js:5)

感谢您的帮助

只需在polyfills.ts中添加这一行

//将全局添加到窗口，分配窗口本身的值。 (任意窗口).global = window;
