我正在做同样的类(class)并且犯了同样的错误。然而，我只是能够修复它。我通过重新安装所有开发依赖项并使用当前版本(而不是类(class)中的版本)来做到这一点。我也将 usemin 命令(根据此处的帖子)更改为

"imagemin": "imagemin img/* --out-dir=dist/img",

但是，它仍然不起作用，所以我使用以下工具检查了所有文件是否有错误:

https://www.freeformatter.com/java-regex-tester.html用于测试 html 文件； http://www.webtoolkitonline.com/javascript-tester.html ，用于测试 .js 文件和 https://jsonlint.com/?json= ，测试 package.json 文件是否有错误。

在我更正所有文件后，命令“npm run build”终于起作用了。 (我特别忘记检查 script.js 文件，我刚刚从仍然包含脚本标签的 html 文件中复制了代码)
