Esy: "esy install" fails to install packages

[ulrikstrid]

I wanted to play with opium and thought I should try esy as well. I cloned the example repo and tried to add opium. I was told that I need to have a higher version of OCaml so I changed it to 4.6.1 and tried again. Then I got the following output.

~/Projects/esy-ocaml-project master ~ esy add @opam/opium
esy add v0.0.70

Tried changing to another OCaml version without success.

When I first cloned the repo everything was working and I could do changes in the files and build etc.

[andreypopp]

This is a depsolver failure, the possible solution would be to add this to a package.json:

"resolutions": {
  "**/@opam/ppxlib": "0.3.0"
}

These lines will make sure we have a single ppxlib in our depgraph.

[ulrikstrid]

That solves my issue but I guess this should stay open as opening issues and getting hand holding is not sustainable 😄 Should probably rename the issue to something more descriptive?

[andreypopp]

I've renamed this issue to collect examples of failures which we need to validate against the new installer (once it ready).

Closing as we have new installer in 0.2.0.
