How to resolve "Missing write access to /usr/local/lib/node_modules" when install expo-cli?

Software Required
- NPM version 6.4.1

Problems

• I'm exploring React and try to install expo-cli by executing command "npm install -g expo-cli", error as shown below is displayed

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules
npm ERR! path /usr/local/lib/node_modules
npm ERR! code EACCES
npm ERR! errno -13
npm ERR! syscall access
npm ERR! Error: EACCES: permission denied, access '/usr/local/lib/node_modules'

• I know this is a common problem and solutions is available over the internet, I think this is necessary to write a small little note for my own jot down.

Steps

• Run command below to resolve the permission problem

$ mkdir ~/.npm-global
$ npm config set prefix '~/.npm-global'
$ export PATH=~/.npm-global/bin:$PATH
$ source ~/.profile

• Run command below to install expo-cli

$ mkdir ~/.npm-global
$ npm config set prefix '~/.npm-global'
$ export PATH=~/.npm-global/bin:$PATH
$ source ~/.profile
$ npm install -g expo-cli

• You are good to create your React project now.
