引入@twilio/Conversations后Angular生产构建报错求助

引入@twilio/Conversations后，执行ng build可正常构建，但执行ng build --prod生产构建时出现以下错误：

ERROR in ../node_modules/twilsock/builds/browser.js
Module build failed (from ../node_modules/@angular-devkit/build-angular/node_modules/@angular-devkit/build-optimizer/src/build-optimizer/webpack-loader.js):

使用版本 #

• Angular: 7.2.2
• Node: 12.14.1
• @twilio/conversations: 2.1.0

已尝试但无效的解决步骤 #

• 降级@twilio/conversations版本
• 升级angular-cli、typescript版本
• 删除并重新安装node_modules
