material-ui#21
react-tap-event-plugin#82

Below dependencies should be updated
material-ui@0.16.3
react-tap-event-plugin@2.0.0

I've updated and fixed (defensively) both material-ui@16.0.3 and react-tap-event-plugin@2.0.0

Hope that helps!

Should be solved by v1.0.3 release. Created a separate issue for updating dependencies including getting material-ui to v0.16.4 and tap-event-plugin to v2.1.0.

What worked for me:

• delete the node_modules/ folder
• npm install

[prescottprue]

@MadeInMoon Yes, that should fix it in an already generated project. If you update using npm i -g generator-react-firebase, then future projects should be good from the start.

You are probably getting this error because you need to update a dependency in your project package.json file. In my case:
"react-tap-event-plugin": "^1.0.0" to "react-tap-event-plugin": "^2.0.0"
after making that change, remove the node_modules folder:
rm -rf node_modules

then finally:
npm install
