没有为 Electron 的入门应用程序定义流程

Question

我正在尝试开始使用 Electron。我已经能够运行所有 simple examples. They all work as expected. When I try to follow the Quick Start Guide I experience the same issue as mentioned in ：应用程序正常启动，但不显示节点 Chrome 和 Electron 的版本。当我查看开发工具时，我看到了这个错误：

Uncaught ReferenceError: process is not defined
    at index.html:14

但是，我已经将nodeIntegration设置为true。

为什么还是不行？

版本：

npm 7.6.3
节点 v14.16.0
铬 89.0.4389.82

操作系统：

Ubuntu 20.04.2 LTS。

index.html

    <meta charset="UTF-8">

<body style="background: white;">

        and Electron

main.js

const { app, BrowserWindow } = require('electron')

function createWindow () {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      nodeIntegration: true
    }
  })

  win.loadFile('index.html')
}

app.whenReady().then(createWindow)

app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', () => {
  if (BrowserWindow.getAllWindows().length === 0) {
    createWindow()
  }
})

package.json

  }
}

Answer 1

尝试在创建您的 BrowserWindow 时设置此值：

webPreferences: { nodeIntegration: true, contextIsolation: false }

一个新的major Electron version has been released打破了教程。
具体的重大更改是 contextIsolation 标志的新默认值。
