Question

我正开始使用angular进行开发，我想实现一个使用electronic和electronic-edge.js的应用程序。

我建立环境没有问题，并且能够使电子起作用。

但是，当我到达想要使用电子边缘的那一刻，我发现它停止工作了...

这些是我遇到的错误：

*0] ERROR in ./node_modules/electron-edge-js/lib/edge.js
0] Module not found: Error: Can't resolve 'fs' in 'C:\Users\testbe\dev\JARVIS\n

0] WARNING in ./node_modules/electron-edge-js/lib/edge.js 101:23-44
0] Critical dependency: the request of a dependency is an expression
0] i ?wdm?: Failed to compile.*

似乎这些错误尚未解决，但对某些人来说仍然可以解决。.我已经测试了很多帖子答案中发现的很多修复程序，但似乎没有任何效果。我可能会想念一些东西。

这是我称为需求的代码，会产生问题：

 declare var require: any
import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'JARVIS';

  edge = require('electron-edge-js');
}


If I remove the "edge = require('electron-edge-js');"  everything works. Thus the electron-edge-js is probably the source of the issue (,well, i'm probably the source of the issue ^^ )

This is the electron.dev.js call at the beginning:

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

// 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;

const createWindow = () => {
    // set timeout to render the window not until the Angular 
    // compiler is ready to show the project    
    setTimeout(() => {
        // Create the browser window.
        win = new BrowserWindow({
            width: 800,
            height: 600,
            icon: './src/favicon.ico'
        });

        // and load the app.
        win.loadURL(url.format({
            pathname: 'localhost:4200',
            protocol: 'http:',
            slashes: true
        }));

        win.webContents.openDevTools();
        window.require('fs');


        // 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;
        });
    }, 10000);
}

// 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 macOS 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 macOS 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();
    }
});

最后一个，即package.json的开头：

 {"name": "jarvis",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "concurrently \"ng serve\" \"npm run electron\"",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "electron": "electron ./src/electron.dev"
  },``

编辑（基于第一个答案）

我尝试添加

    "browser": {
    "fs": false,
    "path": false,
    "os": false
}

放入电子的package.json中。这解决了第一个问题，但产生了一个新问题：

ERROR Error: ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked. Previous value: 'null: 0'. Current value: 'null: 1'.

at Object.debugUpdateRenderer [as updateRenderer] (core.js:11080)
at checkNoChangesView (core.js:10435)

我认为fs是电子所必需的，或者不是^^

我必须在下面的代码中（放在wich文件中）：

    node: {
   fs: "empty"
}

我还看到了这个线程：https://github.com/webpack/webpack/issues/3012

在我的代码中，我没有看到任何“目标：“电子”，我必须在哪里进行测试？

您是否尝试在Webpack.config中添加如下代码？

node: {
   fs: "empty"
}

如果没有，您可以尝试检查一下是否有任何作用。
