Building Troika

[timluther]

Hi,
I'm trying to build troika from source (on windows 11) but I'm having problems and I'm not sure if its an issue with the library or my setup.
I can run 'npm install' but when I try to build using 'npm run build' I get the following error:

build
lerna exec --ignore=troika-examples -- rollup -c $LERNA_ROOT_PATH/rollup.config.js

Does anybody have any ideas?
