應用程序.js

/**CUSTOM_MODULES**/

var module1 = require('module1.js');

/**MODULES_END**/

模塊1.js

function module1(){
    //My code
}

module.exports = module1;

module1.js 與我的 app.js 位於同一目錄中。

我嘗試了無數的事情，但似乎沒有任何效果。

我試過：

 var module1 = require('module1.js');
 var module1 = require('./module1.js');
 var module1 = require('../module1.js');
 var module1 = require('module1');

package.json : app.js

Answer 1

試試 var module1 = require('./module1');

Answer 2

安裝npm -g並在之后重試。

Answer 3

將您的模塊作為應用程序的依賴項添加將解決此問題。 要實現這一點，請嘗試以下命令。

npm install module1 --save

希望這有幫助！

Answer 4

就我而言，在嘗試了一切但沒有成功后，更新節點有所幫助（v10.3.1 -> v12.13.1）。
