【import .node file】Cannot read property 'dlopen' of undefined

alyen028 commented 7 years ago

1、 webpackConfig module: { loaders: [ { test: /.js$/, loader: 'babel-loader' }, { test: /.node$/, loader: 'node-loader' } ] }, resolve: { //自动扩展文件后缀名，意味着我们require模块可以省略不写后缀名 extensions: ['.js', '.json', '.node'], } 2、main.js import node from 'hello.node'; or var dddd = require('./hello.node'); all display errors: Uncaught Error: Cannot open F:\web\event\node_modules\hello.node: TypeError: Cannot read property 'dlopen' of undefined

what 's wrong with it ? thank you for your reply !

While exploring with Chrome-Extension, I installed RobotJS for desktop automation. At runtime, it is throwing the same error given below,

Uncaught Error: Cannot open C:\Users\Ashutec\Desktop\add-to-crm\node_modules\robotjs\build\Release\robotjs.node: TypeError: Cannot read property 'dlopen' of undefined at Object.<anonymous> (chrome-extension://filhinahhlohnlcejgbfooccoeaofjog/scripts/content.js:1) at Object.<anonymous> (chrome-extension://filhinahhlohnlcejgbfooccoeaofjog/scripts/content.js:1) at n (chrome-extension://filhinahhlohnlcejgbfooccoeaofjog/scripts/content.js:1) at Object.<anonymous> (chrome-extension://filhinahhlohnlcejgbfooccoeaofjog/scripts/content.js:1) at n (chrome-extension://filhinahhlohnlcejgbfooccoeaofjog/scripts/content.js:1) at Object.<anonymous> (chrome-extension://filhinahhlohnlcejgbfooccoeaofjog/scripts/content.js:1) at n (chrome-extension://filhinahhlohnlcejgbfooccoeaofjog/scripts/content.js:1) at Object.<anonymous> (chrome-extension://filhinahhlohnlcejgbfooccoeaofjog/scripts/content.js:1) at n (chrome-extension://filhinahhlohnlcejgbfooccoeaofjog/scripts/content.js:1) at chrome-extension://filhinahhlohnlcejgbfooccoeaofjog/scripts/content.js:1

i am facing the same issue on Mac.

mainWindow = new BrowserWindow({ width: 800, height: 600, webPreferences: {nodeIntegration: true} }) webPreferences: {nodeIntegration: true} solved my problem

kreezire commented 5 years ago

@lyanxing, is this with electron? How do we make these changes to make a distributable build?

cap-Bernardito commented 4 years ago

You are probably running the code in a browser. node-loader only works locally on node and electron envs and is not designed to work in a browser.

If the problem is actual, please open a new issue with a minimum reproducible repository.

alexander-akait commented 4 years ago

Other solution is set right target and __dirname:

target: 'node',
node: {
  __dirname: false,
},

webpack-contrib / node-loader
