Unable to install dependencies

Unable to install dependencies

tjdevries opened this issue a year ago · comments

Sorry, maybe I'm just doing this completely wrong, but I was trying to build this to run the examples for myself, but I wasn't able to.

When I try and run:

$ opam update
...
$ opam install .
vcaml on  master via 🐫 v5.0.0 (5.0.0) 
❯ opam install .               
[vcaml.v0.15.0] synchronised (no changes)
[ERROR] Package conflict!
  * Missing dependency:
    - man_in_the_middle_debugger
    unknown package

No solution found, exiting

Maybe there is something super obviously I need to do that I'm just not aware of because I'm relatively new at Ocaml. Would love your thoughts, thanks!

Ah, maybe I just needed to run:

$ opam repo add janestreet-bleeding https://ocaml.janestreet.com/opam-repository

That seems to have fixed it (might want to make a note somewhere in the docs. Just found it by happenstance searching the package name on sourcegraph haha)

It appears I may have spoken too soon:


vcaml on  master via 🐫 v4.14.1 (5.0.0) took 4s 
❯ opam install .

The following actions will be performed:
  ∗ install jsonaf v0.15.0  [required by vcaml]
  ∗ install vcaml  v0.15.0*

Our libraries on github haven't been updated for OCaml 5.0 yet, it's coming soon (next few weeks?) but if you're just trying to build VCaml, I'd recommend downgrading your opam switch to OCaml 4.12

Cool, I'll give that a shot this week. I was hoping to try 5.0 to play with some of the new features and explore ocaml (I'm relatively new to the language), but it's no problem either way.

Thanks for the reply.

hmm, i wasn't able to build with 4.12 or 4.14. Sorry to be a bother

@tjdevries I will reach out to you directly and work with you on debugging your opam environment and getting it built.
