意外令牌：punc (:) [mathjax/es5/sre/mathmaps/de.js:2,19] 升级到 Angular12 后

问题描述

我已将我的 Angular 应用程序升级到版本 12。除了 mathjax 之外，一切正常。在运行 ng serve 时，我收到以下错误

Error: mathjax/es5/sre/mathmaps/de.js from Terser
Unexpected token: punc (:) [mathjax/es5/sre/mathmaps/de.js:2,19]

像 SyntaxError: Unexpected token: punc ()) 这样的几个问题表明包文件中存在无效字符。 下面是 mathjax/es5/sre/mathmaps/de.js:2,19

}

我该如何解决这个错误？更改文件可能不是一个可行的解决方案，因为有来自 6 个不同文件的大约 130 行发生此错误。

构建在 Angular 11 中成功运行

下面是我的 eslint 配置文件

  "root": true,"ignorePatterns": [
    "projects/**/*"
  ],"parserOptions": {
