在 Google App Engine 上部署 Node.js 时出错

尝试将 node.js 应用程序部署到 GAE 时出现错误。我注意到 node.js 运行时无法找到 app.js 中所需的模块。如果我删除 require 语句，它将正常运行。

// in app.js    
var protocol = require("./protocol.js");

部署命令如下：

>gcloud app deploy

几分钟后，日志显示如下错误：

**> [email protected] start /app
> node app.js

module.js:471
    throw err;
    ^

除了检查 var protocol = require("./protocol.js"); 中是否确实使用了双引号（通常需要单引号）外，可能还值得检查模块的目录结构，该结构必须与 require 调用中指示的路径一致。您的 package.json 是什么样子的？
