FAQ常见问题解答---搭建hubot

1、

[root@test160 ~]# npm install -g n npm 
ERR! Error: CERT_UNTRUSTED

证书不受信任的

解决办法：

npm config set strict-ssl false

2、

npm install -g hubot coffee-script yo generator-hubot

查看日志报错信息

原因：gcc版本太低，需要升级到4.9以上

3、

Error: CERT_NOT_YET_VALID

原因：服务器时间设置错误

4、

Your hubot-scripts.json is empty, so you just need to remove it. 
[Tue Apr 03 2018 18:18:50 GMT+0800 (CST)] ERROR hubot-heroku-keepalive included, but missing HUBOT_HEROKU_KEEPALIVE_URL. `heroku config:set HUBOT_HEROKU_KEEPALIVE_URL=$(heroku apps:info -s | grep web.url | cut -d= -f2)` 
[Tue Apr 03 2018 18:18:50 GMT+0800 (CST)] INFO hubot-redis-brain: Using default redis on localhost:6379

出现的错误信息是因为默认情况下，hubot使用redis做持久化存储，并支持heroku部署。

我们可以去掉redis和heroku配置，在./external-scripts.json文件中找到"hubot-heroku-keepalive"和"hubot-redis-brain"并删除即可。

xiaojiang> xiaojiang shellcmd update 

xiaojiang> spawn!

原因待查

6、　

ERROR Error: listen EADDRINUSE 0.0.0.0:8080

上面提示 8080 端口被占用了

[www@test160 handlers]$ netstat -ntlp|grep node
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 0.0.0.0:8100                0.0.0.0:*                   LISTEN      8008/node           
tcp        0      0 0.0.0.0:8080                0.0.0.0:*                   LISTEN      11651/node

可以指定端口执行，比如换 8100 端口：

[www@test160 hubot]$ PORT=8100 ./bin/hubot

7、tmux里执行报错

sessions should be nested with care, unset $TMUX to force

解决：杀掉进程后执行unset TMUX，然后再执行tmux attach就可以了
