我已经开始使用电子js hello world应用程序了 first application with electron
我正在按照指示行事。
创建了3个文件main.js, index.html, package.json
的package.json
{
"name" : "your-app",
"version" : "0.1.0",
"main" : "main.js"
}
main.js
const electron = require('electron');
// Module to control application life.
const {app} = electron;
// Module to create native browser window.
const {BrowserWindow} = electron;
// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win;
function createWindow() {
// Create the browser window.
win = new BrowserWindow({width: 800, height: 600});
// and load the index.html of the app.
win.loadURL(`file://${__dirname}/index.html`);
// Open the DevTools.
win.webContents.openDevTools();
// Emitted when the window is closed.
win.on('closed', () => {
// Dereference the window object, usually you would store windows
// in an array if your app supports multi windows, this is the time
// when you should delete the corresponding element.
win = null;
});
}
// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow);
// Quit when all windows are closed.
app.on('window-all-closed', () => {
// On OS X it is common for applications and their menu bar
// to stay active until the user quits explicitly with Cmd + Q
if (process.platform !== 'darwin') {
app.quit();
}
});
app.on('activate', () => {
// On OS X it's common to re-create a window in the app when the
// dock icon is clicked and there are no other windows open.
if (win === null) {
createWindow();
}
});
// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.
的index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Hello World!</title>
</head>
<body>
<h1>Hello World!</h1>
We are using node <script>document.write(process.versions.node)</script>,
Chrome <script>document.write(process.versions.chrome)</script>,
and Electron <script>document.write(process.versions.electron)</script>.
</body>
</html>
然后安装了Electron Globaly
npm install electron-prebuilt -g
然后尝试使用
运行应用程序electron .
但没有发生任何事情。结果如下
C:\Users\abc\Desktop\electrons\1>electron .
C:\Users\abc\Desktop\electrons\1>
---编辑
我尝试在package.json中添加脚本来启动电子
{ ... “scripts”:{“start”:“electron main.js”} ... }
然后当我使用npm start
运行应用时
结果如下
C:\Users\abc\Desktop\electrons\1>npm start
> your-app@0.1.0 start C:\Users\abc\Desktop\electrons\1
> electron main.js

答案 0 :(得分:1)
如果您使用的是Electron 1.1.0并且没有安装VS2015,那么您可能会错过VC++2015 runtime。

代码对我有用,所以它必须是你环境中的东西。尝试删除项目的node_modules文件夹(rm -rf node_modules
),然后npm i
,然后npm start
(我假设您的package.json中仍有启动任务)。< / p>
