在 Linux 上搭建 Hubot 聊天机器人服务器
1. 先确定安装了 Node.js
如果还没安装Node.js，就先安装Node.js。Node.js是绿色软件，只要解压安装包即可。这里假设已经在/data/node-v5.12.0/目录下安装了 node-v5.12.0 。
2. 安装 Hubot 框架
# npm install -g yo generator-hubot
3. 创建 Hubot 项目
# mkdir myHubot
# cd myHubot
# yo hubot
如果出现错误：
/usr/bin/node: No such file or directory
软连接解决：
# ln -s /data/node-v5.12.0/bin/node /usr/bin/node
# ln -s /data/node-v5.12.0/bin/npm /usr/bin/npm
再试：
# yo hubot
/data/node-v5.12.0/lib/node_modules/yo/node_modules/mkdirp/index.js:90
throw err0;
^
Error: EACCES: permission denied, mkdir '/root/.config'
at Error (native)
at Object.fs.mkdirSync (fs.js:842:18)
at sync (/data/node-v5.12.0/lib/node_modules/yo/node_modules/mkdirp/index.js:71:13)
at Function.sync (/data/node-v5.12.0/lib/node_modules/yo/node_modules/mkdirp/index.js:77:24)
at Object.create.all.get (/data/node-v5.12.0/lib/node_modules/yo/node_modules/configstore/index.js:38:13)
at Object.Configstore (/data/node-v5.12.0/lib/node_modules/yo/node_modules/configstore/index.js:27:44)
at new Insight (/data/node-v5.12.0/lib/node_modules/yo/node_modules/insight/lib/index.js:37:34)
at Object.<anonymous> (/data/node-v5.12.0/lib/node_modules/yo/lib/cli.js:172:11)
at Module._compile (module.js:413:34)
at Object.Module._extensions..js (module.js:422:10)
如果出现上面错误，就执行：
# chmod g+rwx /root
然后再试：
# yo hubot

We're constantly looking for ways to make yo better!
May we anonymously report usage statistics to improve the tool over time?

出现了上面安装提示界面，输入所有者、Hubot 名称和描述等。输好后会根据输入的创建对应的配置文件，然后进行处理，并且安装一些模块文件等。
等待安装完成就可以使用了，执行下面命令。
# ./bin/hubot

出现上面显示，说明机器人正常启动。
4. 验证 Hubot 是否安装完成
在命令行里输入 myHubot ping ，如果能看到回复 PONG，说明 Hubot 就安装完成了。
如下：
myhubot> myHubot ping
myhubot> PONG
注：myHubot ping 中的 myHubot 是你的机器人名称。
5. 查看可以使用哪些命令
想查看可以使用哪些命令，在命令行里输入 myHubot help 。
如下：
myhubot> myHubot help
myhubot> Shell: myhubot adapter - Reply with the adapter
myhubot animate me <query> - The same thing as `image me`, except adds a few parameters to try to return an animated GIF instead.
