Regarding the Webpack warning, it seems like you have more than one folder in node_modules with the same name but different casing. Have you checked that error? Did you find the offending modules?
@floydhartford Did you get this working?
I’m having exactly the same issue.
Following quick start, or cloning a project that works on mac both have exactly the same result.
npm ls react: -- @frontity/core@1.14.3 – react@17.0.2
It seems like a problem with npm 7 and how it handles the peerDependencies, which differs from npm 6. Do you have a React package installed with a peerDependency of React 16 or lower?
