babel-node したときに EADDRINUSEが出た

Posted at

node -v v0.10.25
npm --version 3.7.2
babel-node -V 6.5.1

なんか適当に開発してて babel-nodeしてたら EADDRINUSEとか言われた

Error: listen EADDRINUSE :::80

  • 詳しく言うと2回目以降出る
  • ググるとサーバーがポートを開いたままになってるからIN USEと怒るらしい
hoge.js
 process.on('exit', () => サーバー名.close());

とかしてあげると解決。
