[BUG] dependency of a dependency isn't installed when using npm ci --only=production

[dlcoffee]

What / Why

hi! i have a nextjs project that is dependent on @babel/core. in my ci build (npm ci --only=production), @babel/core isn't included, and is failing my build.

when i load up my node console, i also am not seeing @babel/core.

my current workaround is to recreate my entire package-lock, but i'd rather not do that, as i'd be updating more dependencies than i'd want to at the moment.

Welcome to Node.js v12.6.0.
Type ".help" for more information.
> require('@babel/core')
Thrown:
Error: Cannot find module '@babel/core'

Where

i uploaded my project's package.json/package-lock.json to this repo without any source code

this line should be telling npm to install @babel/core, right? https://github.com/dlcoffee/npm-problem/blob/master/package-lock.json#L14356
