@sykespro It has been a hot minute since I dealt with this error. So, I cannot be 100% sure if this is how I cleared it or not but if you check out this thread I had an issue with yarn rw dev back in RW 0.37 that I resolved by running the following:
yarn --forcethen re-ranyarn rw devand the same error I first reported popped up again…
So, I ran
git clean -fdx -e .envthenyarn install
This cleared up a different error message when running yarn rw dev and I honestly cannot remember if I did this to clear up this error message I experienced in May and that you are now experiencing… but at the very least it may be worth a shot.
