Is this a bug report?

Did you try recovering your dependencies?

yarn --version
1.3.2

Environment

1. node -v: v9.5.0
2. npm -v: 5.6.0
3. yarn --version (if you use Yarn): 1.3.2
4. npm ls react-scripts (if you haven’t ejected):
   template-react-app@0.1.0 /Users/gionagranata/WebstormProjects/template-react-app-copia
   └── react-scripts@1.1.1

Then, specify:

1. Operating system: MasOSX
2. Browser and version (if relevant): not relevant

Actually getting this exact issue on one of my projects with a wildly different setup. If it's a package causing the issue why would this be?

[Timer]

See #4053, reasoning is the same. For now I suggest you place your client code in an isolated folder with it's own node_modules.
