Hello,

I had the same problem.

I deleted node_modules and run "npm install", now it's working.

@anagram3k can you try updating to 0.0.36, deleting your node_modules and running npm install again? Thanks!

[anagram3k]

use package.json from https://github.com/driftyco/ionic/blob/master/CHANGELOG.md#packagejson-updates

npm install @ionic/app-scripts@latest --save-dev
rm -rf node_modules
npm install

Everything works now.

@anagram3k This doesn't work for me :/

Any workaround?

the problem is the number of watches .
I resolve with this command : echo fs.inotify.max_user_watches=582222 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
