node.js - 在 ibm cloud 上启动应用程序时找不到模块 'ibmbluemix'

Question

我最近在 IBM blumix 上开始了我的第一个 NodeJs 应用程序，遵循这些教程 http://ibm-bluemix.coderpower.com/#/warmup/55e07bf49924f792327901cd/code 。我按照说明进行操作，但是当我启动应用程序时，出现错误 Cannot find module 'ibmbluemix'

我的代码和教程一样，我几乎感觉ibm bluemix模块没有安装在云ibm bluemix上。

这是代码包.json

{
"name": "NodejsStarterApp",
"version": "0.0.1",
"description": "A sample nodejs app for Bluemix",
"scripts": {
    "start": "node app.js"
},
"dependencies": {
    "express": "4.12.x",
    "cfenv": "1.0.x"
},
"repository": {},
"engines": {
    "node": "0.12.x"
} 
}

app.js

    var express = require('express');
    var ibmbluemix = require('ibmbluemix');
    var config = {
    applicationId:"FirstAppli",
    applicationRoute:"firstappli.mybluemix.net"
   };
   // cfenv provides access to your Cloud Foundry environment
   // for more info, see: https://www.npmjs.com/package/cfenv
   var cfenv = require('cfenv');

   // create a new express server
   var app = express();

   // serve the files out of ./public as our main files
   app.use(express.static(__dirname + '/public'));

   var router = express.Router();
   router.get('/', /* @callback */ function(req,res){
            ibmbluemix.initialize(config).then(/* @callback */ function(success)      {
                res.json({ message : 'sdk initialised' });
            },
            /* @callback */ function(err){
                res.json({ message : 'sdk error' });
            });
        });

    app.use('/api', router);

    // get the app environment from Cloud Foundry
   var appEnv = cfenv.getAppEnv();

   // start server on the specified port and binding host
   app.listen(appEnv.port, '0.0.0.0', function() {

    // print a message when the server starts listening
   console.log("server starting on " + appEnv.url);
  });

我不明白，我没有尝试在本地测试代码，但令我惊讶的是互联网上没有人遇到与我相同的错误。也许我忘记了一些明显的事情......感谢您的帮助!

PS:我没有使用创建的默认空间，但我创建了一个新空间(否则我无法创建 Node 应用程序)，也许会有一些影响...

您需要将 ibmbluemix 添加为 package.json 文件中的依赖项:

{
"name": "NodejsStarterApp",
"version": "0.0.1",
"description": "A sample nodejs app for Bluemix",
"scripts": {
    "start": "node app.js"
},
"dependencies": {
    "express": "4.12.x",
    "cfenv": "1.0.x",
    "ibmbluemix": "1.0.0"
},
"repository": {},
"engines": {
    "node": "0.12.x"
} 
}

如果您想在本地尝试应用程序，请在更改 package.json 文件后运行以下命令:

# npm install
# node app.js
