Question

我正在使用nodejs版本 - v0.10.31

在一台机器上它可以工作，而在我的机器上却没有。有人可以给我一些建议，我可以开始寻找问题吗？

var express = require('express'),
path = require('path'),
fs = require('fs'),
mongoose = require('mongoose'),
expressSession = require("express-session");

var env = process.env.NODE_ENV = process.env.NODE_ENV || "development";

var config = require('./server/config/config')[env];

var app = express();
var server = app.listen(config.port);

var sessionMiddleware = expressSession({
    name: "dga-cookie",
    secret: "dga-secret",
    store: new (require("connect-mongo")(expressSession))({
        url: config.db,
        auto_reconnect: true
    }),
    saveUninitialized: true,
    resave: true
});

app.use(sessionMiddleware);

var io = require('socket.io')(server);

io.use(function(socket, next){
    sessionMiddleware(socket.request, {}, next);
});

require('./server/config/express')(app, config);

require('./server/config/mongoose')(config);

/* user schema */
var userSchema = mongoose.Schema({
    username: {type: String, required: true, unique: true},
    email: {type: String, required: true, unique: true},
    password: {type: String, required: true},
    activated: {type: Boolean, required: true}
});

var User = mongoose.model('users', userSchema);

require('./server/config/routes')(app);

require('./server/config/rest/user')(app, io, User);

require('./server/config/rest/game')(app, io, User);

并且有package.json：

  "name": "app",
  "version": "0.0.1",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"

Answer 1

我在Windows 8.1上也遇到了同样的错误。该错误是由于系统路径的环境变量缺少“C：\ Windows \ System32 \”值。因此，请右键单击“我的电脑”，转到“属性” - >“高级系统设置” - >“环境”变量。现在打开（编辑）“PATH”变量并将“C：\ Windows \ System32 \”值添加到路径变量的值字段中。保存所有更改。现在关闭Node.js cmd提示符并重新打开它。现在输入nodemon cmd。希望它对你有用。

Answer 2

这是在GET请求之后发生的。我将查看您的路由文件，并查看该上下文中正在使用的文件。

Answer 3

我建议您检查机器上是否安装了mongodb（可执行文件，而不是npm）。当节点尝试执行不存在的程序时，通常会发生此错误。

祝你好运！
