我尝试以下列方式运行 typescript example，这导致了以下错误:

$ mongod --dbpath /home/u/databases
$ npm install
$ tsc --sourcemap --module commonjs app.ts
$ node app.js                             
{ [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' }

此外，查看 db.ts 我认为 package.json 文件中缺少 http 和 url，对吗？

如何使用 mongodb 修复上述错误？

最佳答案

在 Linux 操作系统中，首先从 node_modules 中删除 bson 文件夹并运行此命令:

sudo apt-get install gcc make build-essential 

然后重启nodejs文件如index.js。希望对你有帮助
