Question

我很困惑a）这里的实际错误是什么 - 似乎有一些缺少该模块的人仍然可以启动他们的服务器，b）我该如何解决这个问题？

我试过了：

rm -rf node_modules
npm cache clean
npm install

npm-debug.log没有提供其他错误/明显有用的信息。这是一个使用Express的初学者设置，可以对MongoDB进行小型查询。

npm开始输出：

david@david-desktop:~/Documents/node/nodetest1$ npm start

> nodetest1@0.0.0 start /home/david/Documents/node/nodetest1
> node ./bin/www

Answer 1

Port 3000 is already in use

请尝试终止在端口3000上运行的旧进程或尝试使用其他端口。

Answer 2

您可以参考此文章来终止在端口号3000上运行的进程

Find (and kill) process locking port 3000 on Mac

否则，更改端口号

Node.js无法启动服务器
