編譯角度項目時出錯

Question

[ERROR in ./node_modules/stompjs/lib/stomp-node.js Module not found: Error: Can't resolve 'net' in 'C:\ANGULAR\websocket-example\node_modules\stompjs\lib'][1]

通過npm install stompjs --save添加到angular

導入到component.ts中。 import * as Stomp from 'stompjs';

並在使用這種方法時出現錯誤let socket = new WebSocket("ws://localhost:8080/greeting"); let ws = Stomp.over(socket); let socket = new WebSocket("ws://localhost:8080/greeting"); let ws = Stomp.over(socket);

Answer 1

要將外部庫添加到您的angular項目中，可以將其添加到angular.json

"scripts":[
   "node_modules/stompjs/lib/stomp-node.js"
]
