What is the current behavior?

When running yarn with the minimum specified node version, the command fails with the following output stating @angular/[email protected] needs a higher version

error @angular/[email protected]: The engine "node" is incompatible with this module. Expected version ">= 8.9.0".

Expected behavior:

Running yarn with node version matching the minimum specified version, the command should succeed and all dependencies should be installed.

Minimal reproduction of the problem with instructions:

nvm install 8.6
nvm use 8.6
yarn

Version of affected browser(s),operating system(s), npm, node and ngrx:

app	version
ngrx	6.0.0-beta.1
node	< 8.9.0
