'TypeError: Cannot read property \'ssl\' of undefined

[wangxh0812]

运行环境:ubuntu-16.04 node v4.5.0
启动命令: node app.js
启动报错：message: 'Cannot read property 'ssl' of undefined',
stack: 'TypeError: Cannot read property 'ssl' of undefined\n at async.auto.network (/home/wangxh/awork/blockchain/ebookcoin/ebookcoin-master/app.js:221:20)
执行if (scope.config.ssl.enabled) 这行代码时出错
具体代码段：

network: ['config', function (cb, scope) {
            var express = require('express');
            var app = express();
            var server = require('http').createServer(app);
            var io = require('socket.io')(server);
            if (scope.config.ssl.enabled) {
                var privateKey = fs.readFileSync(scope.config.ssl.options.key);
                var certificate = fs.readFileSync(scope.config.ssl.options.cert);
                var https = require('https').createServer({
                    key: privateKey,
                    cert: certificate
                }, app);
                var https_io = require('socket.io')(https);
            }
            cb(null, {
                express: express,
                app: app,
                server: server,
                io: io,
                https: https,
                https_io: https_io
            });
        }]

目前，系统受环境限制，建议：

操作系统使用 ubuntu 14.04.*
Node.js的版本使用 0.12.*

后续的版本，会逐步更新到最新的lts版本。

应该不是版本的问题，我把环境切成ubuntu 14.04.5 nodejs 0.12.15 还是报同样的错误，把function (cb, scope) 改成function ( scope,cb)就可以了，但是不知道这个参数是从哪儿传过来的

[wangxh0812]

network: ['config', function (cb, scope) {将这段代码改成network: ['config', function ( scope,cb) {包括dbSequence,sequence,balancesSequence等，就可以执行起来了

[imfly]

async最新版本是2.0.0，修改了一些Api，比如这里的.auto函数，最新版确实应该使用network: ['config', function ( scope, cb)，也更符合一贯的编码习惯，即：把回调放在最后。 不过，咱们暂时不做升级了。

It's OK.
