缺少依赖项：./node_modules/node-pre-gyp/lib/info.js 中的 aws-sdk

【中文标题】缺少依赖项：./node_modules/node-pre-gyp/lib/info.js 中的 aws-sdk

【英文标题】：Missing Dependency: aws-sdk in ./node_modules/node-pre-gyp/lib/info.js

【问题描述】：

我有一个使用 vue-cli-plugin-electron-builder 构建的新 Vue/Electron 应用程序，它将使用 sqlite。

在我运行yarn add sqlite3 之前，基本安装在开发中运行良好。然后我会看到 aws-sdk 缺少依赖项错误。

研究表明这是一个 webpack 问题，可以使用 webpack externals 修复。

并且，来自vue-electron-builder docs 的类似解释和修复。

我已经基于此更新了我的 vue.config.js 和 webpack.config.js 文件，但现在已经有几个小时没有解决了。

任何帮助或建议表示赞赏。谢谢。

【参考方案1】：

更多研究使我找到了this 线程，该线程解决了“sqlite3 未定义错误”但创建了一个新错误“需要未找到”，需要将 nodeIntegration = true 添加到 vue.config.js 中。

// working solution vue.config.js

module.exports = 
   pluginOptions: 
       electronBuilder: 
           externals: ['sqlite3'],
           nodeIntegration: true
         ,
       
;
