NPM start 在 package.json 中导致来自 "gulp clean && gulp frontend && gulp dev" 的无法解释的错误

Question

我遵循这个 Tutorial 直到我到达 前端任务 步骤，这就是运行 NPM 和 npm start 给我以下错误：

我发现问题是我在 package.json 中更改的这段代码：

package.json: “start”: “gulp clean && gulp frontend && gulp dev”, “build”: “gulp clean && gulp

或我对上述教程的前端部分之后的 gulpfile.js 所做的更改： 注意：我安装了最新的 Node 和 NPM。

错误代码：

 $ npm start

> gulp clean && gulp frontend && gulp dev

Answer 1

EADDRINUSE 错误意味着您尝试侦听的端口已被使用。停止正在使用它的应用程序或选择不同的端口号。

Answer 2

Error: listen EADDRINUSE 127.0.0.1:8000

表示您尝试使用的端口（此处为 :8000）已占线。您是否还有以前的应用程序实例运行？如果是，则将其杀死并重试。当然，请尝试查看该端口上是否有其他服务运行并停止它。
