Compile error

[rockyhwang]

Hi I got following errors after run tsc index.ts command. I modify the "target" and "lib" attribute value in tsconfig.json to the newer es version. But, it does not work at all. Please advise what should I do further to conquer the problems. Thanks a lot!

Thanks @rockyhwang, not sure what you are trying to do, but have you tried running just npm run build?

Hi Henry, I think the issues are related es version as I illustrated as follows. Even I add in some values to upgrade the configuration in tsconfig.json above ES5 version. It does not work to resolve these compile errors. Anyway, thanks for your comments.

@rockyhwang, following up, have you tried directly running

npm i followed by npm run build
