copy Electron 离线环境打包解决方案（electron-forge） 未尝试

1.在线环境准备

1. 创建新项目：

2. # 创建并进入项目目录
   mkdir my-electron-app && cd my-electron-app
   
   # 初始化项目
   npm init -y
   
   # 安装 electron
   npm install --save-dev electron
   
   # 安装 electron-forge
   npm install --save-dev @electron-forge/cli @electron-forge/maker-squirrel @electron-forge/maker-zip @electron-forge/maker-deb @electron-forge/maker-rpm
   
   # 使用 electron-forge 转换项目
   npx electron-forge import
   

3. 下载所需的离线资源包

4. # 在项目根目录创建离线资源文件夹
   mkdir electron-offline-packages
   cd electron-offline-packages
   
   # 下载需要的 npm 包
   npm pack electron
   npm pack @electron-forge/cli
   npm pack @electron-forge/core
   npm pack @electron-forge/maker-squirrel
   npm pack @electron-forge/maker-zip
   npm pack @electron-forge/maker-deb
   npm pack @electron-forge/maker-rpm
   
   # 下载 Electron 二进制文件
   # 从 https://npmmirror.com/mirrors/electron/ 下载对应版本
   # 例如下载 v25.9.8 版本:
   wget https://npmmirror.com/mirrors/electron/25.9.8/electron-v25.9.8-win32-x64.zip
   wget https://npmmirror.com/mirrors/electron/25.9.8/electron-v25.9.8-win32-ia32.zip
   wget https://npmmirror.com/mirrors/electron/25.9.8/SHASUMS256.txt

5. 创建完整的项目模板：项目结构：

6. my-electron-app/
   ├── src/
   │   ├── index.html
   │   ├── index.css
   │   ├── index.js
   │   └── preload.js
   ├── electron-offline-packages/
   │   ├── electron-25.9.8.tgz
   │   ├── electron-forge-cli-6.4.2.tgz
   │   ├── electron-v25.9.8-win32-x64.zip
   │   └── ...
   ├── package.json
   ├── forge.config.js
   └── .npmrc

7. package.json:

8. {
     "name": "my-electron-app",
     "version": "1.0.0",
     "description": "My Electron App",
     "main": "src/index.js",
     "scripts": {
       "start": "electron-forge start",
       "package": "electron-forge package",
       "make": "electron-forge make"
     },
     "author": "author",
     "license": "ISC",
     "dependencies": {
       "electron-squirrel-startup": "^1.0.0"
     },
     "devDependencies": {
       "@electron-forge/cli": "^6.4.2",
       "@electron-forge/maker-deb": "^6.4.2",
       "@electron-forge/maker-rpm": "^6.4.2",
       "@electron-forge/maker-squirrel": "^6.4.2",
       "@electron-forge/maker-zip": "^6.4.2",
       "electron": "25.9.8"
     }
   }

9. forge.config.js:

10. module.exports = {
      packagerConfig: {
        asar: true,
        download: {
          mirror: "https://npmmirror.com/mirrors/electron/",
          cache: "./electron-cache"
        }
      },
      rebuildConfig: {},
      makers: [
        {
          name: '@electron-forge/maker-squirrel',
          config: {
            name: 'my_electron_app'
          }
        },
        {
          name: '@electron-forge/maker-zip',
          platforms: ['darwin', 'win32']
        }
      ]
    };

     

11. .npmrc:

12. registry=https://registry.npmmirror.com/
    electron_mirror=https://npmmirror.com/mirrors/electron/
    electron-custom-dir=25.9.8

13. 打包整个项目：

14. # 将项目打包为 zip
    zip -r electron-project-template.zip my-electron-app

2.离线环境使用

1. 解压项目模板：

2. unzip electron-project-template.zip
   cd my-electron-app

    

3. 创建 electron 缓存目录：

4. mkdir -p electron-cache/electron/25.9.8

    

5. 复制 Electron 二进制文件：

6. # 将之前下载的 electron 二进制文件复制到缓存目录
   cp electron-offline-packages/electron-v25.9.8-win32-x64.zip electron-cache/electron/25.9.8/
   cp electron-offline-packages/SHASUMS256.txt electron-cache/electron/25.9.8/

    

7. 离线安装依赖

8. # 安装离线包
   npm install ./electron-offline-packages/*.tgz

    

9. 执行打包：

10. # 打包应用
    npm run make

     

11. 打包后的输出目录：

12. out/
    ├── make/
    │   └── squirrel.windows/
    │       └── x64/
    │           ├── my_electron_app-1.0.0 Setup.exe
    │           └── ...
    └── my-electron-app-win32-x64/
        └── my-electron-app.exe

    3.网络问题

• 离线环境 npm run make 时会出现 econnrefuesd ip地址 错误 这个错误是因为在离线环境下还在尝试连接 npm 镜像源。
• 需要完全禁用网络请求： 首先修改 .npmrc 文件：

• registry=https://registry.npmmirror.com/  //或者换成本地代理地址http://localhost:4873/
  electron_mirror=file:///D:/Electron/my-electron-app/electron-cache/ //换成
  electron_custom_dir=25.9.8
  offline=true
  prefer-offline=true
  no-proxy=true
  https-proxy=false
  proxy=false

   

• 修改 forge.config.js：

• module.exports = {
    packagerConfig: {
      asar: true,
      download: {
        mirror: "file:///D:/Electron/my-electron-app/electron-cache/",
        cache: "./electron-cache",
        force: false
      },
      electronZipDir:'./electron-cache/electron/25.9.8/' // 这行☆☆☆☆☆
    },
    makers: [
      {
        name: '@electron-forge/maker-squirrel',
        config: {
          name: 'my_electron_app'
        }
      },
      {
        name: '@electron-forge/maker-zip',
        platforms: ['win32']
      }
    ],
    // 添加离线配置 ☆☆☆☆☆
    electronRebuildConfig: {
      onlyModules: [],
      force: false,
      offline: true
    }
  };

   

• 确保电子缓存目录结构正确：

• electron-cache/
  └── electron/
      └── 25.9.8/
          ├── electron-v25.9.8-win32-x64.zip
          ├── electron-v25.9.8-win32-ia32.zip (如果需要)
          └── SHASUMS256.txt

   

• 运行打包时使用离线模式：

• # Windows
  set ELECTRON_ENABLE_OFFLINE_MODE=1
  npm run make --offline
  
  # Linux/Mac
  export ELECTRON_ENABLE_OFFLINE_MODE=1
  npm run make --offline
