Steps to reproduce:

? Which template would you like to use?: Custom JavaScript Component
? What kind of component do you want to build?: Output component
? What do you want to name your component?  Name must be dash-delimited and all lowercase. E.g. 'my-component-name' abc
? Enter destination directory: ../abc
Setting up abc component package...

cd ../abc
npm install
npm run build
pip install -e .
cd example-app 
shiny run app.py

This is caused by a name conflict between your module (abc) and the built in python abc module "Abstract Base Class". I'm not sure there's much we can do to protect folks against that error, so I'm going to go ahead and close this.
