Edits: You can use npm i --save @angular/platform-server

Depending on the error, you can install using npm i @angular/platform-browser to install it manually. This is how I solved the issue on my side.

PS: please use --save flag to save it on your local machine like this npm i --save @angular/platform-browser too.

i'm using angular 13 and installed angular universal uning: ng add @nguniversal/express-engine

encountered similar issue: 'Cannot find module '@angular/platform-server' or its corresponding type declarations.ts(2307)'

had to manually install and save this package:

npm i --save @angular/platform-browser
