Unable to resolve dependency tree when running npm install

[scottdlai]

I created a project by running bsb -init rescript-test -theme react-hooks from the Getting Started Guide

Output

Hey, new ReasonReact user here, I run into similar problem (MacOS Big Sur 11.1, npm 7.0.15, node v15.4.0, bsb 8.4.2).
As a workaround, I resolved dependencies by running this in the project:

npm i -D bs-platform@"^7.1.1".

BTW, on Linux with npm 6.14.6, node v14.6.0, bsb 8.4.2 it npm installs fine.

Wow, @miles-d solution works

Thanks so much!

This is not good for the platform, have any contributors actually looked into this?

Released a new version (0.10.0) that should fix any installation issue with latest bs-platform (v9). Let me know if you find any issues and will try to fix them.

Thanks for reporting those and sorry for the late response/fix.
