🔥 Exception or Error

node_modules/@angular/compiler-cli/index.d.ts:20:10 - error TS2305: Module '"@angular/compiler-cli/src/ngtools_api"' has no exported member 'NgTools_InternalApi_NG_2'.

20 export { NgTools_InternalApi_NG_2 as __NGTOOLS_PRIVATE_API_2 } from './src/ngtools_api';
            ~~~~~~~~~~~~~~~~~~~~~~~~

Anything else relevant?

Adding --skipLibCheck TypeScript compiler option is a workaround:

npx tsc --strict --noEmitOnError --lib es2015,dom --skipLibCheck index.ts

I have typescript@3.1.1 & still getting the same error. Any progress with this issue?

I just have tried the 9.0.0-rc.3 release and the issue is gone. So closing as resolved.
