    Try adding the param --legacy-peer-deps to npm install.
    Does the install work without errors now?

    More info on --legacy-peer-deps.

    I went the full fix and removed the @nestjs packages from package.json, then reinstalled them with npm i @nestjs/common @nestjs/core @nestjs/platform-express --save.
    My package.json looked like so:
    package.json file

    If you’ve already ran an npm install and have a node_modules folder, delete that folder and the package-lock.json file too, prior to running the above install command.
