awso-async.0.9.0 is not installed. Install it? [Y/n] y
  * No agreement on the version of ocaml-base-compiler:
    - (invariant) -> ocaml-base-compiler = 4.14.2
    - awso-async -> ocaml >= 5.3.0 -> ocaml-base-compiler >= 5.3.0~
    You can temporarily relax the switch invariant with `--update-invariant'
  * Incompatible packages:
    - (invariant) -> ocaml-base-compiler = 4.14.2
    - awso-async -> ocaml >= 5.3.0 -> ocaml-variants < 5.6.1~
  * Missing dependency:
    - awso-async -> ocaml >= 5.3.0 -> ocaml-variants < 5.6.1~ -> system-msvc
    unmet availability conditions: 'os = "win32"'
