Error while installing node module in ReactJs

Question

I just cloned a React application from Git that doesn't have node_modules on it. I try to install with command npm install but unable to do it. Following error occurs when installing the npm.

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

I even tried with npm install --legacy-peer-deps but doesn't work. How can I fix this issue?
