Answer 1

You don't have write access to the directory

/usr/local/lib/node_modules/react-native-cli

As you're going to install the library globally, you need admin permissions, so do that as root using sudo command:

sudo npm install -g react-native-cli

Answer 2

if the error persists and showing you that the symlink is already exists

npm ERR! EEXIST: file already exists, symlink '../lib/node_modules/react-native-cli/index.js' -> '/usr/local/bin/react-native'
npm ERR! File exists: /usr/local/bin/react-native

add --force

sudo npm install -g react-native-cli --force
