'egg-sequelize server online error:Class constructor LRUCache cannot be invoked without 'new'？

Now, i am using eggjs to develop a system and the program running in the local environment is okay. but when i set up my program in the server, the problem informed me that： error:

I find a similar solution in the github sequelize/sequelize#7840:https://github.com/sequelize/sequelize/issues/7840.

or another discussrion tell me i should use lower version of Lrucaache version. https://github.com/isaacs/node-lru-cache/issues/147

The advice is modify the .babelrc etc . Actually, I dont have the file in my project, though i used babel package. i try to add the file .babelrc and other advice appeared in the below discussion.

but it didnt work at all.

The server can run in the server correctly.

node.jssequelize.js
