Hi @adrianparr,

Thanks for the report. This is a common issue with NPM 7/8 due to its change in peer dependency management.

While the error is technically correct since @imgix/gatsby does not explicitly state that it is compatible with Gatsby 4, you should be able to safely ignore it and continue with installation.

You can use npm install gatsby-source-prismic --legacy-peer-deps until @imgix/gatsby updates its package.

You can find more detailed installation instructions, including gatsby-source-prismic's own peer dependencies, on this page: Install the Gatsby Source Plugin - Prismic

Hi angeloashmore,

Thank you for your speedy reply. I'll give it a try. Cheers.
