启动服务器时找不到模块“express-stormpath”
当我尝试运行node server.js （在普通的terminal，而不是一个超级用户或根），我得到这个错误：
alphaunlimitedg@AUNs-PC:~/my-webapp$ node server.js module.js:442 throw err; ^ Error: Cannot find module 'express-stormpath' at Function.Module._resolveFilename (module.js:440:15) at Function.Module._load (module.js:388:25) at Module.require (module.js:468:17) at require (internal/module.js:20:19) at Object.<anonymous> (/home/alphaunlimitedg/my-webapp/server.js:2:17) at Module._compile (module.js:541:32) at Object.Module._extensions..js (module.js:550:10) at Module.load (module.js:458:32) at tryModuleLoad (module.js:417:12) at Function.Module._load (module.js:409:3) alphaunlimitedg@AUNs-PC:~/my-webapp$
我用root，superuser和normaluser命令安装了express软件包： npm install express
它的工作，没有给任何错误！ 但它仍然显示上面的错误。 任何想法如何解决这个问题？
PS：这是我遵循的程序如下所示：

这个错误意味着你的server.js文件包含语句require('express-stormpath'); 但该模块不在您的/<project>/node_modules文件夹中。
您可以通过在您的项目目录中执行npm i --save express-stormpath来解决此问题。
