Nodejs使用pkg打包为可执行文件

安装pkg

npm install -g pkg

查看pkg命令

pkg --help

修改package.json

新增bin入口配置

{
  "name": "takescreenshot",
  "version": "1.0.0",
  "bin": "app.js",   // 新增bin入口配置
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "description": "",
  "dependencies": {
    "express": "^4.21.1",
  }
}

打包

默认打包

pkg .

如果上面package.json没有配置bin的话,可以执行

pkg .\app.js

指定打包的文件名

pkg . --target win --output 你的文件名.exe

报错解决

进入网站: https://github.com/vercel/pkg-fetch/releases

找到我报错的tag的版本,点进这个版本的详情

找到报错的对象的name值里面的版本号信息

例如上面我的报错的版本是16.16.0,那就在网站上面找到这个版本

下载报错的name的名称对应文件

我报错的是{"tag":"v3.4","name":"node-v16.16.0-win-x64"}

则在这里找到node-v16.16.0-win-x64点击下载

下面的v3.4是上面报错的对象的tag属性的值

找到C:\Users\22560\.pkg-cache\v3.4文件夹

将上面下载的文件放到文件夹内,并重命名为fetched-v16.16.0-win-x64

同理:linux和macos下载也是一样,复制到该文件夹内然后将前缀node改成fetched即可

然后重新pkg .即可
