Something looks wrong in your directory structure. I would nuke the node_modules directory and redo the npm command.
您的目录结构看起来有些错误。我会核对 node_modules 目录并重做 npm 命令。
It's always a good idea to maintain a package.json file and see the dependencies written out
维护一个 package.json 文件并查看写出的依赖项总是一个好主意
cd getFoo
npm init # answer the qestions
npm install --save request
node app.js

I had the same problem, and i installed the request package like that: "npm install request --save" and that solved the problem.
我遇到了同样的问题，我安装了这样的请求包：“npm install request --save”并解决了问题。
