error in 'npm run build'

Thanks so much for making your code available on github! I tried following your build instructions, and got the following errors while running 'npm run build':

Do you know what I can do to fix this? Thanks very much!

How to add documents once at the web screen ?

Hi David, thanks too for yr code and the nice setup to serve the web page locally in the browser.

I get a message that npm is deprecated and replaced on Arch Linux. It does not prevent me from installing and running install scripts though.
Most importantly, I'm missing something basic about how to add documents for analysis.
Does one add them in txt format ? and whatever the format, "exactly" how ?
I've added document using their local path-names, but results make no sense as txt doc contents do not seem to be parsed. Instead the path-names appear to be parsed. ???
Last what would be extra nice would be adding to yr README.md file, a path to uninstall everything (for people, who like me don't want to launch a VM) after trying 'lda-topic-modelling' engine out.
Thanks.
