javascript - TypeError：无法读取未定义的属性“data_paths”

问题描述

从 2014 年开始，我一直在关注一个任意但绝对出色的教程。我什至无法超越第一部分。

我在处理一些非常基本的导出时遇到错误。首先，我会记下我的代码（多么令人反感）并检查我的错误

包.json：

 {
  "name": "hoarserver",
  "version": "0.0.1",
  "private": true,
  "dependencies": {
    "minimist": "*",
    "extend": "*",
    "binary-parser": "*",
    "mongoose": "*",
    "underscore": "*"
  }
}

server.js：

require(__dirname + '/Resources/config.js');

var fs = require('fs');
var net = require('net');

var i_files = fs.readdirSync(__dirname + "/Initializers");
i_files.forEach(function(file) {
    console.log('Loading initializers ' + file);
    require(__dirname + "/Initializers/" + file);
});
var model_files = fs.readdirSync(__dirname + "/Models");
model_files.forEach(function(file) {
    console.log('Loading models ' + file);
    require(__dirname + "/Models/" + file);
});
tiles = {};
var tile_files = fs.readdirSync(config.data_paths.tiles);
tile_files.forEach(function(file) {
    console.log('Loading tile ' + file);
    var tile = require(config.data_paths.tiles + file);
    tiles[tile.tid] = tile;
});

console.log(config.database);

配置.js：

var args = require('minimist')(process.argv.slice(2));
var extend = require('extend');

//Store the environment variable
var environment = args.env || "test";

//Common config... ie: name, version, max player etc...
var common_conf = {
  name:  "HOARServer",
  version: "0.0.1",
  environment: environment,
  data_paths: {
      tiles: __dirname + "\\Game Data\\" + "Tiles\\",
      cosmetics: __dirname + "\\Game Data\\" + "Cosmetics\\",
      objects: __dirname + "\\Game Data\\" + "Objects\\"
  }
};

var conf = {
    production: {
        ip: args.ip || "0.0.0.0",
        port: args.port || 8081,
        database: "mongodb://127.0.0.1/hoar_p"
    },

    test: {
        ip: args.ip || "0.0.0.0",
        port: args.port || 8082,
        database: "mongodb://127.0.0.1/hoar_t"
    }
};

extend(false, conf.production, common_conf);
extend(false, conf.test, common_conf);

module.exports = config = conf[environment];

问题出现在 Webstorm 建议config元素尚未导出的地方，尽管它在导出时被（hackily）定义为conf[environment]. 当我运行代码时，配置运行 server.js，环境设置为test; 我漂亮的控制台输出不仅告诉我 data_paths 未定义，它还告诉我配置 ITSELF 也未定义！:)

var tile_files = fs.readdirSync(config.data_paths.tiles);
                                       ^

TypeError: Cannot read property 'data_paths' of undefined
