You may need to add fusion-plugin-universal-events to your project

That fixed it! Should be added when you run yarn create fusion-app my-fusion-app

peer dependency was missing so I added it

Perfect!

from fusion-cli.

This is most likely caused by being on yarn >1.10.0 and not on the latest version of fusion-cli

You can fix this by running either uber-web upgrade --match fusion --force (to upgrade all fusion packages in lockstep), yarn upgrade fusion-cli (to upgrade only fusion-cli), or downgrading yarn (via brew, but not recommended since new machines may not have brew formulas for older yarn versions)

(From FusionJS - fusion dev EADDRINUSE)

Could you give that a try and let us know if that resolves it?

from fusion-cli.

I cant access the instance of Stack Overflow (its probably for Uber employees).

uber-web upgrade --match fusion --force

I dont have uber-web. Is this an uber internal cli?

yarn upgrade fusion-cli

Just ran this, and it blew up (when I run yarn dev):

error: (client) ./node_modules/fusion-plugin-react-router/dist/browser.es2017.es.js
Module not found: Error: Can't resolve 'fusion-plugin-universal-events' in '/Users/user/Development/fusion-app/node_modules/fusion-plugin-react-router/dist'

from fusion-cli.

Ah yeah, uber-web upgrade is an internal CLI utility we use to upgrade Fusion dependencies (built on top of yarn upgrade).

Ideally you are on the latest versions for all fusion-* packages (which that tool would help with). Does yarn upgrade-ing all of the Fusion.js packages resolve this?

You may need to add fusion-plugin-universal-events to your project if you do not have it already, as fusion-plugin-react-router has a peerDependency on it.

from fusion-cli.

error: (client) ./node_modules/fusion-plugin-react-router/dist/browser.es2017.es.js
Module not found: Error: Can't resolve 'fusion-plugin-universal-events' in '/Users/user/Development/fusion-app/node_modules/fusion-plugin-react-router/dist'

I actually ran into this myself recently, the peer dependency was missing so I added it: fusionjs/fusion-plugin-react-router@7c9ffb4. But this hasn't been published in a new version just yet.
