Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires root/req 1.* -> satisfiable by root/req[1.0.0].
    - root/req 1.0.0 requires dep/pkg ^1 -> found dep/pkg[1.0.0, 1.0.1, 1.0.2] but it conflicts with your temporary update constraint (dep/pkg:^2).
