node.js运行npm失败

事情是这样的,我在自学node.js,照着书上的实例,我执行这一步

express -e ejs myapp

然后按照提示执行这一步

$ cd myapp && npm install

但是总是不能成功,错误提示是这样的(此处已修改,我将报错开始以后的地方都贴出来了)

希望高手能解答一下,谢谢了


好吧,评论里面有人让我贴一下npm-debug.log的代码,但是我不是很懂,我贴一下吧(不全,问题字数有限制),如下:


第三次修改,采纳评论建议,贴出npm-debug.log最后几行代码,如下:

新问题:我现在碰到了一个新的问题,就是我现在npm install运行成功了,但是我执行项目里的app.js却执行不起来。不知道是什么问题?

    microblog的入口不是 app.js 这个项目用npm管理的

    你看 package.json 中 启动命令行是
    node ./bin/www
    入口是这个文件 监听端口和初始化代码也在这个文件里

    用npm管理的项目 启动不用执行指定js文件 直接无脑 npm start 就可以了

      卧槽,我最后提的那个问题居然被我这个菜鸟解决了,但绝对没科学道理,我说一下,我看了用我的环境生成的app.js

      var express = require('express');
      var path = require('path');
      var favicon = require('static-favicon');
      var logger = require('morgan');
      var cookieParser = require('cookie-parser');
      var bodyParser = require('body-parser');
      
      var routes = require('./routes/index');
      var users = require('./routes/users');
      
      var app = express();
      
      // view engine setup
      app.set('views', path.join(__dirname, 'views'));
      app.set('view engine', 'ejs');
      
      app.use(favicon());
      app.use(logger('dev'));
      app.use(bodyParser.json());
      app.use(bodyParser.urlencoded());
      app.use(cookieParser());
      app.use(express.static(path.join(__dirname, 'public')));
      
      app.use('/', routes);
      app.use('/users', users);
      
      /// catch 404 and forward to error handler
      app.use(function(req, res, next) {
          var err = new Error('Not Found');
          err.status = 404;
          next(err);
      });
      
      /// error handlers
      
      // development error handler
      // will print stacktrace
      if (app.get('env') === 'development') {
          app.use(function(err, req, res, next) {
              res.status(err.status || 500);
              res.render('error', {
                  message: err.message,
                  error: err
              });
          });
      }
      
      // production error handler
      // no stacktraces leaked to user
      app.use(function(err, req, res, next) {
          res.status(err.status || 500);
          res.render('error', {
              message: err.message,
              error: {}
          });
      });
      
      module.exports = app;
      

      -----------------------------------分割线------------------------------------

      然后是书上案例的app.js,是这个样的

      /**
      
      Module dependencies.
      */
      var express = require('express')
        , routes = require('./routes');
      
      var app = module.exports = express.createServer();
      
      // Configuration
      
      app.configure(function(){
        app.set('views', dirname + '/views');
        app.set('view engine', 'ejs');
        app.use(express.bodyParser());
        app.use(express.methodOverride());
        app.use(app.router);
        app.use(express.static(dirname + '/public'));
      });
      
      app.configure('development', function(){
        app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
      });
      
      app.configure('production', function(){
        app.use(express.errorHandler());
      });
      
      // Routes
      
      app.get('/', routes.index);
      
      app.listen(3000);
      console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env);
      

      我发现我的app.js少一个“app.listen(3000);”,于是我手动加了一个到我的app.js里,然后就跑起来了,但是我不知道,为什么我的app.js里没有这句话,求大神解释,相关参数如下:
      系统:Macosx
      node版本:v0.10.28
      express版本:4.2.0
      npm版本:1.4.9

        因为在bin目录下的www文件已经有listen这句话了。正常用npm start启动的话是启动的www这个文件。
