Nodejs使用pkg打包為可執(zhí)行文件的解決方案

使用pkg將Node.js項(xiàng)目打包為可執(zhí)行文件時(shí),可能會(huì)遇到一些常見的錯(cuò)誤,如未指定目標(biāo)平臺(tái)、在遠(yuǎn)程緩存中找不到基礎(chǔ)Node.js二進(jìn)制文件等,本文介紹了如何通過配置package.json中的bin入口、手動(dòng)下載指定版本的Node.js二進(jìn)制文件到本地.pkg-cache目錄解決這些問題

安裝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

默認(rèn)打包

pkg .

如果上面package.json沒有配置bin的話,可以執(zhí)行

pkg .\app.js

指定打包的文件名

pkg . --target win --output 你的文件名.exe
