testcontainers-mysql.0.1.0 is not installed. Install it? [Y/n] y
  * No agreement on the version of ocaml:
    - (invariant) -> ocaml-base-compiler = 4.14.2 -> ocaml = 4.14.2
    - testcontainers-mysql -> testcontainers -> ocaml >= 5.0
    You can temporarily relax the switch invariant with `--update-invariant'
  * Incompatible packages:
    - (invariant) -> ocaml-base-compiler = 4.14.2
    - testcontainers-mysql -> testcontainers -> ocaml >= 5.0 -> ocaml-variants >= 5.4.1~
