问题描述

我正在尝试为 mongodb uni 课程做作业.他们给了我们一些文件，说明是:

I am trying to do a homework for a mongodb uni course. They gave us some files, instructions are:

运行 npm install mongodb 然后 node app.js

出于某种原因，npm install 没有创建 node_modules 目录，但我没有看到任何构建错误:

for some reason npm install does not create a node_modules directory but I don't see any build errors:

npm init
