By far the easiest way to use SQLite with electron is with electron-builder .到目前为止，将 SQLite 与电子一起使用的最简单方法是使用electron-builder 。
First, add a postinstall step in your package.json:首先，在 package.json 中添加安装后步骤：
"scripts": {
"postinstall": "install-app-deps"
...
}
and then install the necessary dependencies and build:然后安装必要的依赖项并构建：
npm install --save-dev electron-builder
npm install --save sqlite3
npm run postinstall
electron-builder will build the native module for your platform, with the correct name for the Electron binding;电子构建器将为您的平台构建本机模块，并为电子绑定提供正确的名称； and you can then require it in code as normal.然后你可以像往常一样在代码中require它。
See my github repo and blog post - it took me quite a while to figure this out too.请参阅我的github 存储库和博客文章- 我也花了很长时间才弄清楚这一点。

I would not recommend the native node sqlite3 module.我不会推荐本机节点 sqlite3 模块。 It requires being rebuild to work with electron.它需要重建才能与电子一起使用。 This is a massive pain to do - At least I can never get it to work and their a no instructions to for rebuilding modules on windows.这是一个巨大的痛苦 - 至少我永远无法让它工作，而且他们没有关于在 Windows 上重建模块的说明。
Instead have a look at kripken's 'sql.js' module which is sqlite3 that has been compiled 100% in JavaScript.而是查看 kripken 的“sql.js”模块，它是在 JavaScript 中 100% 编译的 sqlite3。 https://github.com/kripken/sql.js/ https://github.com/kripken/sql.js/

Two aspects are to be considered here:这里要考虑两个方面：
- Setting
NODE_PATH: this lets electron know where to find your modules (see this answer for a thorough explanation)设置NODE_PATH：这让电子知道在哪里可以找到您的模块（有关详细解释，请参阅此答案） - Compiling native modules against electron headers: see official docs针对电子头文件编译本机模块：请参阅官方文档
And checkout the following questions, that ask the same thing:并检查以下问题，这些问题提出了同样的问题：
- Electron App with Database 带数据库的电子应用程序
- Using NodeJS plugins in Elelectron 在 Elelectron 中使用 NodeJS 插件
My tip would be to give lovefield (by Google) a try.我的建议是尝试lovefield (by Google)。

I was having same problem.我遇到了同样的问题。 Tried everything and atlast this worked for me :-尝试了一切，最后这对我有用：-
npm install --save sqlite3
npm install --save electron-rebuild
npm install --save electron-prebuilt
.\node_modules\.bin\electron-rebuild.cmd
This will create "electron-v1.3-win32-x64" folder in .\\node_modules\\sqlite3\\lib\\binding\\ location which is used by electron to use sqlite3.这将在 .\\node_modules\\sqlite3\\lib\\binding\\ 位置创建“electron-v1.3-win32-x64”文件夹，电子使用它来使用 sqlite3。
Just start application and you will be able to use sqlite3 now.只需启动应用程序，您现在就可以使用 sqlite3。

A simpler solution:一个更简单的解决方案：
- Install electron-rebuild
npm i electron-rebuild --save-dev安装electron-rebuild npm i electron-rebuild --save-dev - Launch electron-rebuild
./node_modules/.bin/electron-rebuild(or.\\node_modules\\.bin\\electron-rebuild.cmdon windows)启动电子重建./node_modules/.bin/electron-rebuild（或.\\node_modules\\.bin\\electron-rebuild.cmd在 Windows 上） - Go to " node_modules/sqlite3/lib/binding/ " and rename the folder " electron-v0.36-darwin-x64 " to " node- v47 -darwin-x64 "转到“ node_modules/sqlite3/lib/binding/ ”并将文件夹“ electron-v0.36-darwin-x64 ”重命名为“ node- v47 -darwin-x64 ”
PS: v47 is my version, be careful to choose the good one (in your case v45 ) PS： v47是我的版本，小心选择好的（你的情况是v45 ）

npm install --save sqlite3
npm install --save-dev electron-rebuild
Then, in the scripts of your package.json, add this line:然后，在 package.json 的脚本中，添加以下行：
"scripts": {
"postinstall": "electron-rebuild",
...
},
Then just re-install to trigger the post-install:然后只需重新安装即可触发安装后：
npm install
Works flawlessly for me in a complex use case also involving electron-builder, electron-webpack and sequelize.在一个复杂的用例中对我来说完美无缺，还涉及电子构建器、电子网络包和续集。
It works in electron-webpack's dev mode and in production mode for both Windows and Linux.它适用于 electron-webpack 的开发模式和 Windows 和 Linux 的生产模式。

I encounter this error too.我也遇到这个错误。 Here is how i solve it: npm install --save-dev electron-rebuild then: ./node_modules/.bin/electron-rebuild这是我解决它的方法： npm install --save-dev electron-rebuild然后： ./node_modules/.bin/electron-rebuild
from: https://electronjs.org/docs/tutorial/using-native-node-modules来自： https : //electronjs.org/docs/tutorial/using-native-node-modules
ps: While it's on rebuilding, don't use npm start to lanch the electron app. ps：在重建过程中，不要使用npm start来npm start电子应用程序。 Otherwise the rebuild process would fail.否则重建过程将失败。

它适用于版本 3 和 4，不幸的是版本 5。有关详细信息，请参阅 sqlite3 文档： https : //www.npmjs.com/package/sqlite3#custom-builds-and-electron或以其他方式运行以下行： npm install sqlite3 --runtime=electron --target=4.0.0 --dist-url=https://atom.io/download/electron

Have a look at a similar answer here看看这里的类似答案
TL;DR TL; 博士
cd .\node_modules\sqlite3
npm install nan --save
npm run prepublish
node-gyp configure --module_name=node_sqlite3 --module_path=../lib/binding/electron-v1.3-win32-x64
node-gyp rebuild --target=1.3.2 --arch=x64 --target_platform=win32 --dist-url=http://electron.atom.io/ --module_name=node_sqlite3 --module_path=../lib/binding/electron-v1.3-win32-x64

You can manually build the native modules using visual studio.您可以使用 Visual Studio 手动构建本机模块。
- Download visual studio 2019.下载 Visual Studio 2019。
- Install package "desktop development with c++".安装包“使用 c++ 进行桌面开发”。 In installation details tab select "MSVC v140 - VS 2015 C++ build tools (v14.00)"在安装详细信息选项卡中选择“MSVC v140 - VS 2015 C++ 构建工具（v14.00）”
- Download electron-builder in your project.在您的项目中下载电子生成器。
In package.json create a script.
在 package.json 中创建一个脚本。 "scripts": { "postinstall": "install-app-deps" } “脚本”：{“安装后”：“安装应用程序”}then run the script.
然后运行脚本。
