找不到模塊啓動服務器

Question

當「快車stormpath」當我嘗試運行node server.js（在普通的終端沒有被超級用戶或root）我得到這個錯誤：

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$ 

我已經安裝了快遞包裹在根，超級用戶和normaluser與命令：npm install express

它的工作，沒有給任何錯誤！但它仍然顯示上面的錯誤。任何想法如何解決這個問題？

PS：這是我已經按照以下步驟操作：

alphaunlimitedg@AUNs-PC:~$ npm install express

Answer 1

的錯誤意味着你server.js文件中包含的聲明require('express-stormpath');但該模塊沒有位於您/<project>/node_modules文件夾中。

您可以在項目目錄中通過執行npm i --save express-stormpath來解決此問題。
