egg在本地运行没有问题，线上代码出现问题错误日志： 8 ERROR 33 nodejs.SequelizeConnectionError: Class constructor LRUCache cannot be invoked without 'new’ at Promise.tap.then.catch.err (/usr/src/BDMS/bdmsback/node_modules/sequelize/lib/dialects/mysql/connection-manager.js:133:19) at tryCatcher (/usr/src/BDMS/bdmsback/node_modules/bluebird/js/release/util.js:16:23) at Promise._settlePromiseFromHandler (/usr/src/BDMS/bdmsback/node_modules/bluebird/js/release/promise.js:517:31) at Promise._settlePromise (/usr/src/BDMS/bdmsback/node_modules/bluebird/js/release/promise.js:574:18) at Promise._settlePromise0 (/usr/src/BDMS/bdmsback/node_modules/bluebird/js/release/promise.js:619:10) at Promise._settlePromises (/usr/src/BDMS/bdmsback/node_modules/bluebird/js/release/promise.js:695:18) at _drainQueueStep (/usr/src/BDMS/bdmsback/node_modules/bluebird/js/release/async.js:138:12) at _drainQueue (/usr/src/BDMS/bdmsback/node_modules/bluebird/js/release/async.js:131:9) at Async._drainQueues (/usr/src/BDMS/bdmsback/node_modules/bluebird/js/release/async.js:147:5) at Immediate.Async.drainQueues [as _onImmediate] (/usr/src/BDMS/bdmsback/node_modules/bluebird/js/release/async.js:17:14) at runCallback (timers.js:705:18) at tryOnImmediate (timers.js:676:5) at processImmediate (timers.js:658:5) name: "SequelizeConnectionError" parent: {} original: {} pid: 33 我在git上面找到一个解决方法，说是babel转义产生的问题：https://github.com/sequelize/sequelize/issues/7840 我按照里面的建议进行了部分修改，发现并没有变好
但是按照提供的参考意见是上面第二个修改babel的配置，所以想问下egg-script在哪里可以修改Babel的设置。只是在package-json.lock上看到有指定babel目录 谢谢啦
