Here is my package.json: 这是我的package.json:
{
"name": "breef",
"version": "1.0.0",
"description": "A simple chat application.",
"main": "index.js",
"dependencies": {
"electron": "^1.4.12"
},
"devDependencies": {},
"scripts": {
"test": "breeftestcmd",
"start": "node index.js"
},
"keywords": [
"breef"
],
"author": "Sage & Sh4wn",
"license": "ISC"
}
Here is my index.js: 这是我的index.js:
var app = require("app")
var browserWindow = require("browser-window")
app.on('ready', function() {
var mainWindow = new browserWindow({
width: 800,
height: 600
})
mainWindow.loadUrl('http://google.com');
})
If app is a module, it's missing in your package.json. 如果app是模块,则package.json中缺少该模块。 If not, you should use a path to require it
如果没有,您应该使用一条路径来要求它
var app = require('./app');
The guide you followed is out of date, as of Electron v1.0.0 the way built-in Electron modules are imported has changed. 自从Electron v1.0.0起,导入的电子模块的导入方式已更改,因此您遵循的指南已过时。 This is the correct way:
这是正确的方法:
const {app, BrowserWindow} = require("electron")
You may also find it beneficial to read the previous question that covered this topic: What's the proper way to require in Node.js? 您可能还会发现阅读涉及该主题的上一个问题很有帮助: Node.js中要求的正确方法是什么?
