生成--prod期间来自Terser的运行时错误

问题描述

我已经更新了Angular的所有内容，现在当我
时出现以下错误(4x)构建--prod"

I have updated everything Angular and am now getting the error below (4x) when I
"Build --prod"

如果我删除--prod，则没有错误

No errors if I remove --prod

我在此应用中没有真实代码.这只是一个入门级shell.

I have no real code in this app. It is just a starter shell.

关于要研究什么的任何建议?

Any suggestions on what to look into?

推荐答案

最近发布的Terser 3.16版本这是 Terser和 Terser作为Webpack插件.

It seems to be a problem with the recently released version 3.16 of Terser, here's the related issue in Terser and in Terser as a Webpack plugin.

在此VueJS问题中，他们建议将其降级到版本3.14.1.您可以在package.json中查找包含"terser"的行并将其固定，如下所示:

In this VueJS issue they recommended to downgrade it to version 3.14.1. You can do it looking for the line in package.json containing "terser" and pin it as follows:

    "terser": "3.14.1",
