节点 Js 错误 Module.js 549

Question

在启动我的应用程序时，我收到此错误。 我已经检查并看到所需的模块已安装好，并且还为其提供了全局访问权限。

Hussains-MacBook-Pro:NodeRest-Shop Hussain$ npm start

> noderest-shop@1.0.0 start /Users/Hussain/Desktop/Development/Web/NodeRest-Shop
> nodemon server.js

module.js:549
    throw err;
    ^

Answer 1

如您的日志中所示，您缺少binary-extensions模块：

错误：找不到模块“二进制扩展”

可能是您缺少一些依赖项或忘记包含它。

您可以使用npm安装它：

 npm install binary-extensions

并在您的项目中包含 binaryExtensions ：

const binaryExtensions = require('binary-extensions');

Answer 2

我通过运行解决了这个问题：

npm i npm@latest -g

Answer 3

检查你的 app.js 文件，你的索引路由应该是app.use(require('./routes/')); 不是app.use(require('./routes/index'));
