Error after initial setup

[PabloCorso]

I'am experiencing an error after the initial setup. The solution I found was to install react-router-dom. Has anyone seen this?

Steps:

1. Create project

> npx create-epic-app@latest

? Would you like to set up deployment right now? No

2. Run project (error)

> npm run dev

> predev
> npm run build:icons --silent

> dev
> cross-env NODE_ENV=development MOCKS=true node ./server/dev-server.js

Sorry for the trouble! I've tried this myself and have not had any issues. I'm not sure what could be causing issues for you. What version of npm are you running?
