Ignore a platform specific dependency to be bootstraped

[Kapcash]

Hello!

I'm using Lerna 5.3.0 with Nx enabled and yarn workspace.

My monorepo consists of several web apps, all sharing a common layer (a package call "shared").
And I have this package which requires a npm module which is only supported on windows and MacOS (not linux). So this package cannot be installed on a linux CI/CD.

Is there a way to exclude this package to be bootstraped (i.e. avoid installing its dependencies) when I run yarn install or lerna bootstrap?

I'm deploying to heroku using the heroku/nodejs buildpack, so I have no control on the yarn command and can't use the --ignore-platform option that would probably have made the trick... :(

Any idea to avoid this error while installing a platform specific dependency at bootstrap?
