Hi @VivithaAlamur, It looks like those errors are all asking the same thing. Have you tried running npm i @types/node and adding node to the types field in your tsconfig? If you have, I'll work on reproducing and resolving this.

[klaytaybai]

@VivithaAlamur, one thought is that your @types/node is two major versions behind. The current version is 10.12.21. Using the caret range won't update you to major versions. If you are able to do so, could you please try updating to the newest version and see if that fixes your problem?

[VivithaAlamur]

@klaytaybai i updated the "@types/node": "^10.12.21" to latest and i added "types": ["node"] in tsconfig.app.json file but the issue still exist.

@klaytaybai for angular7 app this is working, if i am trying to creating the library using the angular cli this is not working (ng build libraryname --prod).

[hughjdavey]

I am also having this issue on Angular 7, with latest (11.9.4) version of @types/node and the "types": ["node"] declaration in tsconfig.json

[hughjdavey]

In case it helps anyone, what finally worked was putting "types": ["node"] in src/tsconfig.app.json and not tsconfig.json

@VivithaAlamur Does @hughjdavey's suggestion resolve your issue?

[VivithaAlamur]

Yeah that is working for me .Thank you
