lots of TypeScript errors

使用 yarn web 重现失败，并将 ESLint 插件冲突与 TypeScript 诊断分开处理。检查报告中的 node_modules/javascript-obfuscator/src/... 文件以及 tsconfig 或 jsconfig；编译期间不再出现依赖项错误即表示完成。

I'm experiencing many TypeScript errors (I cropped the cmd output).
As pointed out in https://github.com/microsoft/TypeScript/issues/40426 , you can not disable type checking on *.ts files from packages in node_modules, only on *.d.ts files.
Can the files be changed from *.ts files to *.d.ts files?
