box% stack install profunctor-optics
 Error: While constructing the build plan, the following exceptions were encountered:
 In the dependencies for profunctor-optics-0.0.2:
    coapplicative must match >=0.0.1 && <0.2, but the stack configuration has no specified version (no package with that name found,
                  perhaps there is a typo in a package's build-depends or an omission from the stack.yaml packages list?)
needed since profunctor-optics is a build target.
 In the dependencies for rings-0.1.3:
    base-4.9.1.0 from stack configuration does not match >=4.10 && <5.0  (latest matching version is 4.14.0.0)
    magmas must match >=0.0.1 && <1.0, but the stack configuration has no specified version  (latest matching version is 0.0.1)
needed due to profunctor-optics-0.0.2 -> rings-0.1.3
 Some different approaches to resolving this:
   * Build requires unattainable version of base. Since base is a part of GHC, you most likely need to use a different GHC version
    with the matching base.
 Plan construction failed.
