you didn't include information related typescript version, i'll assume it's ts >=2.0.

in case, need include @types/core-js in package.json. in addition that, need point core-js types in tsconfig.json (or either tsconfig-aot.json)

"typeroots": [ "./node_modules/@types" ]

if specify types manually, then...

"typeroots": [ "./node_modules/@types" ], "types": [ "core-js", ...(other types manually specify) ]

hope helps.
