Error when running 'npm install' and 'npm start' - react-native

Question

I ran npm install in my project directory.
But I get this error while running npm install:
D:\Personal\██████████████████████████████████████████████████████████████\rn-starter-main>npm install

npm install --force installed the packages, but when I run npm start, I get the following error:
D:\Personal\████████████████████████████████████████████████████████\rn-starter-main>npm start

Unable to find expo in this project - have you run yarn / npm install yet?
For the conflicting peer dependency error, I tried:
npm install --legacy-peer-deps and
npm install --force
But none of them seems to have worked. This error is still persisting.
For the expo not found error, I tried commands like:
npm cache clean,
expo install,
expo update,
npm add expo
expo rebuild etc.
I thought this error might be due to older expo versions like 36 and 37 that I've worked with, so, I uninstalled all of Node and NPM and downloaded them again from https://nodejs.org/en/ , but I still get the same "conflicting peer dependency" and "Unable to find expo" errors. Could you please help me with this? Thank you.

Answer 1

Running the command npm install -g expo-cli fixes both the errors. These errors are just due to npm not being installed globally.
