Question

我有一个使用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时遇到错误

我逐步遵循了指南（https://update.angular.io/）

以下是错误：

我不知道什么是错的，谷歌并没有帮助我的线索既不

Answer 1

当前的terser版本存在问题，到目前为止，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",，请确保删除^。

角5到7更新，更简洁的错误后不能建立督促
