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?)
    lawz must match >=0.1.1 && <0.2, but the stack configuration has no specified version  (latest matching version is 0.1.1)
    rings must match >=0.1.3 && <0.1.4, but the stack configuration has no specified version  (latest matching version is 0.1.3)
needed since profunctor-optics is a build target.
 Some different approaches to resolving this:
   * Recommended action: try adding the following to your extra-deps in /home/joel/tmp/haskell-playground/stack.yaml:
 - lawz-0.1.1@sha256:08753bcd245ac05351bd0f6dea2567db1ccaeb5d0ed40e2ddb3f4ae68d759974,1210
