我有一个带有 Angular 5.2 的 Angular-cli 项目。我更新到 Angular 7.2.3。一切正常，ng serve , ng test ，但是当我想ng build --prod我收到错误

我一步一步跟着指南(https://update.angular.io/)

以下是错误:

我不知道出了什么问题，谷歌也没有帮助我

Answer 1

这是当前版本的 terser 有问题，现在，您应该在 package.json 中将版本设置为 3.14.1，如下所示:"terser": "3.14.1",
如果您有 "terser": "^3.14.1",一定要删除 ^ .
