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

【问题标题】：Missing Dependency: aws-sdk in ./node_modules/node-pre-gyp/lib/info.js缺少依赖项：./node_modules/node-pre-gyp/lib/info.js 中的 aws-sdk
【发布时间】：2021-04-06 16:03:31
【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。

【解决方案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
         },
       }
};

其他参考 vue-electron-builder native modules
