Error installing sudo-free NPM packages

Question

I have this difficulty, I wonder if it would be possible to run without sudo

MacBook-Air-de-Alan:~ collins$ npm i -g react-native-cli

Use nvim to edit the ~/. bashrc file and add these lines:

npm set prefix ~/.npm
PATH="$HOME/.npm/bin:$PATH"
PATH="./node_modules/.bin:$PATH"

After that, run the command:

source ~/.bashrc
