eggjs使用中遇到的坑

1.mongoose4.x以上启动的时候报的错误

egg-scripts] Save log file to /root/logs
[egg-scripts] Wait Start: 1...
[egg-scripts] Wait Start: 2...
[egg-scripts] tail -n 100 /root/logs/master-stderr.log
[egg-scripts] Got error when startup:
[egg-scripts] /usr/local/www/egg_server/node_modules/_egg@2.13.0@egg/lib/application.js:69
[egg-scripts]       throw e;
[egg-scripts]       ^
