`npx react-native-macos-init` expects a project with installed dependencies

[kraenhansen]

Environment

react-native -v:
20.0.2
npm ls react-native-macos:
MacOSTestApp@0.0.1 /Users/kraen.hansen/Repositories/react-native-node-api/apps/macos-test-app
└── (empty)
node -v:
v22.19.0
npm -v:
10.9.3
yarn --version:
N/A
xcodebuild -version:
Xcode 16.2
Build version 16C5032a

Steps to reproduce the bug

Following the steps https://microsoft.github.io/react-native-windows/docs/rnm-getting-started, while also passing --skip-install to the @react-native-community/cli init call:

1. npx @react-native-community/cli init MacOSTestApp --skip-install --version 0.78 --directory ./macos-test-app
2. cd macos-test-app
3. npx react-native-macos-init

Expected Behavior

I'd expect to either:

1. init the MacOS app in the newly created app without having to install dependencies, this is needed because I want to do this only once -- or
2. get a nice error asking me to run npm install before initializing the MacOS part.

Actual Behavior

I get the following error when running the last command:

Reading application name from package.json…
Reading react-native version from node_modules…
Reading react-native-macos version from node_modules…
Latest matching version of react-native-macos for react-native@0.81.4 is react-native-macos@0.79.0.

Reproducible Demo

N/A

Additional context

Haven't dug more into this, but a workaround exists (running npm install or not passing --skip-install

any updates on that?

Getting the same error. Got the following message on running npx react-native-macos-init --verbose

I think it's expected you run yarn install, and maybe we can make that more clear in the getting started guide or in the output message?
