Unexpected Error: Unknown configuration tag "INDEX" #1339

Open heptarri opened 1 month ago

heptarri commented 1 month ago

When I create a new project following Your First OCaml Program, The vscode editor show me 5 errors:

Unknown configuration tag "INDEX" ocamllsp
Unknown configuration tag "INDEX" ocamllsp
Unknown configuration tag "INDEX" ocamllsp
Unknown configuration tag "SOURCE_ROOT" ocamllsp
Unknown configuration tag "UNIT_NAME" ocamllsp

I don't know weather the ocaml-lsp has something wrong or my configuration is wrong. Looking forward to the solution.

Thanks for your report @heptarri. What version of OCaml and ocaml-lsp-server are you using ? You can run opam list to show the versions. And opam update && opam upgrade to update. Recent versions of ocaml-lsp-server should either understand these configuration directive or ignore them.

I have the same error.

When I use opam upgrade to get the new version of ocaml-lsp-server, it said:


The following packages are not being upgraded because the new versions conflict with other installed packages:
  - base.v0.17.1
  - ocaml-config.3
  - ocaml-lsp-server.1.18.0
  - omd.2.0.0~alpha4
  - ppx_yojson_conv_lib.v0.17.0
  - sexplib0.v0.17.0
  - stdio.v0.17.0
  - uucp.15.1.0
  - uuseg.15.1.0
However, you may "opam upgrade" these packages explicitly, which will ask permission to downgrade or uninstall
the conflicting packages.
Nothing to do.

Could you provide the output of opam list ? If you are using a version of ocaml-lsp-server that is older than 1.15.0 it would explain the issue.

FWIW: Had a similar issue after a fresh installation on Ubuntu 22.04 LTS after running opam update && opam upgrade

Opam upgrade:

Everything as up-to-date as possible (run with --verbose to show unavailable upgrades).

The following packages are not being upgraded because the new versions conflict with other installed packages:
  - base.v0.17.1
  - ocaml-config.3
  - ocaml-lsp-server.1.18.0
  - omd.2.0.0~alpha4
  - ppx_yojson_conv_lib.v0.17.0
  - sexplib0.v0.17.0
  - stdio.v0.17.0
  - uucp.15.1.0
  - uuseg.15.1.0
However, you may "opam upgrade" these packages explicitly, which will ask permission to downgrade or uninstall the
conflicting packages.
Nothing to do.
