lambda-term.1.13 is not installed. Install it? [Y/n] y
* Incompatible packages:
- (invariant) -> ocaml-base-compiler = 5.4.1
- lambda-term < 2.0 -> jbuilder -> ocaml < 5.0 -> dkml-base-compiler
You can temporarily relax the switch invariant with `--update-invariant'
* Incompatible packages:
- (invariant) -> ocaml-base-compiler = 5.4.1
- lambda-term < 2.0 -> jbuilder -> ocaml < 5.0 -> ocaml-variants (< 4.05.2~ | >= 4.06.0)
* Missing dependency:
- lambda-term < 2.0 -> jbuilder -> dune < 2.0 -> ocaml < 4.12 -> ocaml-base-compiler (<= 3.07+1 | = 3.07+2 | = 3.08.0 | = 3.08.1 | = 3.08.2 | = 3.08.3 | = 3.08.4 | = 3.09.0) | ocaml-system (<= 3.07+1 | = 3.07+2 | >= 3.08.0) | ocaml-variants < 3.09.1~
not available because the package is pinned to version 5.4.1
unmet availability conditions, e.g. 'sys-ocaml-version = "5.4.1" & (os != "win32" | sys-ocaml-libc = "msvc")'
no matching version
* Missing dependency:
- lambda-term < 2.0 -> jbuilder -> ocaml < 5.0 -> ocaml-variants >= 4.06.0 -> ocaml-beta
unmet availability conditions: 'enable-ocaml-beta-repository'
* Missing dependency:
- lambda-term < 2.0 -> jbuilder -> ocaml < 5.0 -> ocaml-variants >= 4.06.0 -> system-msvc
