我开始用angular开发,我想用electron和electron-edge.js实现一个应用程序。
我设置的环境没有问题,并能够使电子作品。
然而,当我到达的时刻,我想使用电子边缘,我发现停止工作...
以下是我遇到的错误:

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

0] Critical dependency: the request of a dependency is an expression
0] i ?wdm?: Failed to compile.*

看来这些错误还没有修复一些人..我已经测试了很多修复中发现了很多后回答,但似乎没有什么工作。我可能错过了一些东西。
这是我调用生成问题的需求的代码:

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');
}

如果我删除“边缘=需要('electron-edge-js');“一切正常。因此,电子边缘js可能是问题的根源(嗯,我可能是问题的根源)

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();
    }
});

最后是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):
我试着补充

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

到electron的package.json中。这解决了第一个问题,但产生了一个新问题:

我认为fs对于电子是必要的,或者不是。
我必须把下面的代码放在哪里(在哪个文件中?):

node: {
   fs: "empty"
}

我还看到了这条线索:https://github.com/webpack/webpack/issues/3012
在我的代码中,我没有看到任何“目标:“电子”,我得把它放在哪里做测试?

hc2pp10m

hc2pp10m1#

您是否尝试在Webpack.config中添加类似下面的代码?

node: {
   fs: "empty"
}

如果没有,你可以试一下,看看是否有什么不同。
