I have a Gatsby starter (taylorbryant/gatsby-starter-tailwind) that uses gatsby-plugin-postcss which is not compatible with the version of gatsby installed in my machine like a few other plugins used in the starter. You can see the warning I get when trying to build for production.
warn Plugin gatsby-plugin-postcss is not compatible with your gatsby version 3.14.2 - It requires gatsby@^2.0.0
How can I downgrade Gatsby to a specific version, maybe just locally?
