I'm not sure how to install (npx) a package from github registry when that package is depending on one or multiple packages from the public npm registry.

I tried:

npm_config_registry=https://npm.pkg.github.com npx @octopol/development

But it fails because some of the dependencies are located on the public npm registry:

npm ERR! code E404
npm ERR! 404 Not Found - GET https://npm.pkg.github.com/@era-ci%2futils - npm package "utils" does not exist under owner "era-ci"
npm ERR! 404
npm ERR! 404  '@era-ci/utils@^2.0.27' is not in this registry.
npm ERR! 404 You should bug the author to publish it (or use the name yourself!)
npm ERR! 404
npm ERR! 404 Note that you can also install from a
npm ERR! 404 tarball, folder, http url, or git url.

I'm not sure how all github-npm-registry customers are using this registry. What am I missing here?
