Original issue by @aravindvakil on 2019-03-21T09:17:04Z

Unable to do production build in ionic 3.19.0. I've checked the related AOT build error in the issue list and can't able to find a solution. The error is in @angular/core. I've given the package.json below.

typescript should be pinned to ~2.6.2.

I've tried to pin typescript to ~2.6.2. but, it failed.

npm i typescript@~2.6.2 --save

You can try to run with cmd run as administrator. Or you can modify package.json, delete node_modules folder and re-install again with npm i

You can try to run with cmd run as administrator. Or you can modify package.json, delete node_modules folder and re-install again with npm i

It is showing the same AOT build error
