Steps to reproduce:

1. Follow the instructions in the readme for building on ubuntu.
2. When you run npm install you get the following error:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: [email protected]
npm ERR! Found: [email protected]
npm ERR! node_modules/react

npm ERR! node_modules/react-file-input
