trueDry install with the current Coq version:
opam install -y --show-action coq-io-hello-world.1.2.0 coq.8.4.5[NOTE] Package coq is already installed (current version is 8.4.5).
The following dependencies couldn't be met:
- coq-io-hello-world -> coq-io >= 4.0.0 -> coq >= 8.5 -> coq-core -> ocaml >= 4.09.0
base of this switch (use `--unlock-base' to force)
- coq-io-hello-world -> coq-io >= 4.0.0 -> coq >= 8.5 -> ocaml >= 4.05.0
base of this switch (use `--unlock-base' to force)
Your request can't be satisfied:
- No available version of coq satisfies the constraints
No solution found, exiting
Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:
opam remove -y coq; opam install -y --show-action --unlock-base coq-io-hello-world.1.2.0truetrueNo files were installed.
