生成期间从运行时错误 - 生成错误

Question

我更新了Angular的所有内容,当我
"Build --prod" 时,我现在得到下面的错误(4x)

如果我删除--prod没有错误

我在这个应用程序中没有真正的代码.它只是一个入门外壳.

关于要研究什么的任何建议？

ERROR in runtime.82c6613acef8f7246fe8.js from Terser

Answer 1

这似乎是最近发布的Terser 3.16版本的一个问题,这里是 Terser和Terser中作为Webpack插件的相关问题.

在这个VueJS问题中,他们建议将其降级到版本3.14.1.您可以按如下方式查找package.json包含"terser"和固定它的行:

    "terser": "3.14.1",

Answer 2

正如Pietro Saccardi所说,到目前为止,有必要将package.json中的Terser版本修复为3.14.1,如下所示: "terser": "3.14.1"

不要^在版本中使用它,否则它可以升级到3.16.
