Can't find or choose sandboxes

[Fibii]

After following the installation guidelines, when I try to choose a sandbox using OCaml: Select a Sandbox for this Workspace I don't see any sandboxes, Opam switches doesn't contain anything either

This issue has been fixed by upgrading to opam v2.1.0, here's some info about the env If you want to reproduce this issue

charaf@fibi:~/Documents/programming/ocaml$ opam --version
2.0.5
charaf@fibi:~/Documents/programming/ocaml$ ocamllsp --version
1.4.1
charaf@fibi:~/Documents/programming/ocaml$ ocamlc -v
The OCaml compiler, version 4.08.1
Standard library directory: /home/charaf/.opam/ocaml-base-compiler.4.08.1/lib/ocaml
charaf@fibi:~/Documents/programming/ocaml$ opam switch

AFAIU, this is caused by #831

--global seems not supported in opam v < 2.1

[tizoc]

Same problem here, got it working again by upgrading opam to 2.1

[rgrinberg]

@Khady could you send a patch for this? We can check the version of opam first.

[Khady]

I'll have a look

• fixed in fix: restore compat with opam 2.0.x #884

[samouri]

I think I'm having this problem too. OCaml Platform extension can't find any sandboxes or opam switches:

opam  - 2.1.3
ocaml  - 4.14.0
ocamllsp - 1.14.2

opam switch:

#  switch   compiler      description
→  default  ocaml.4.14.0  default
