Tallstack theme - ERESOLVE unable to resolve dependency tree

Hi, I'm trying to install the tallstack theme into Wave but I'm getting 'ERESOLVE unable to resolve dependency tree'

npm  ERR!  code ERESOLVE
npm  ERR!  ERESOLVE unable to resolve dependency tree
npm  ERR! While resolving: **undefined**@**undefined**
npm  ERR! Found: **tailwindcss**@**2.2.6**
npm  ERR!  node_modules/tailwindcss

npm  ERR! Could not resolve dependency:
npm  ERR!  peer **tailwindcss**@"**^1.0**" from **@tailwindcss/custom-forms**@**0.2.1**

npm  ERR! Fix the upstream dependency conflict, or retry
npm  ERR! this command with --force, or --legacy-peer-deps
npm  ERR! to accept an incorrect (and potentially broken) dependency resolution.

I've tried updating everything with no joy - I tried to --force the command on a backup version which seemed to work but then the watch command didn't work with this error: Unknown argument: --hide-modules which maybe an outdated webpack thing? Any ideas guys?
