It seems that the GitHub registry we have setup for the preview builds isn't mirroring packages from npm.
As a consequence, you may see installation failures non-preview @metamask packages when using an .npmrc file setup to point at the GitHub registry. I've found that I can get past the error by ensuring the non-preview packages are installed locally before putting the .npmrc file in-place. This is a viable workaround but it requires frequently adding and removing this file, which is rather inconvenient.
