I was using perfectly until upgraded Material UI 4.3 from 4.0.
Successfully installed Material-ui/core, but failing while coming to install icons package.
$ npm i @material-ui/icons
npm ERR! Cannot read property 'match' of undefined
npm ERR! A complete log of this run can be found in:

Delete your package.lock.json file and then run npm i it would work fine
