I don't think this package is currently published to npm with --access=public:
$ curl https://registry.npmjs.org/@mapbox/eslint-plugin-mapbox
{"error":"Not found"}
This is an issue for node-pre-gyp which depends on it (transitively through @mapbox/eslint-config-mapbox) mapbox/node-pre-gyp#930.
If possible could this package be made public?
