When I run my ReactJS, I get this error: 

Unhandled Rejection (Error): Material-UI: react@16.3.0 or greater is required.
▶ 15 stack frames were collapsed.

How do I fix this?

    As respectfully as I can ask, did you even attempt to solve this at all? Did you even read the error? `react@16.3.0 or greater is required` -- What version of React are you running, and is it 16.3.0 or greater? – Mark C. Oct 14 '18 at 22:45

The Material-UI version which you are using requires react version greater than 16.3.0 do you need to install the latest React

To install go to the root folder where package.json is available, execute below command

  npm i -s react

The above command will install React latest version which will fix the issue for you

Or

  npm i -s react@16.3.0

The above command will install React version 16.3.0 which will fix the issue for you

Make sure you update react-dom as well when you update react
