Compilation error when running with elixir-lsp

[sashaafm]

Hello, I've been using elixir-lsp with vim for some time now and it always worked perfectly.

Recently, for whatever reason I can't figure out, elixir-lsp fails to work properly because it can't compile hackney, throwing this error (this is the log from elixir-lsp running with CoC in vim):

I'm not sure if this is actually a problem with hackney or something else related to elixir-lsp or CoC.

I'm running this in Mac OS 10.15.5 with Elixir 1.10.4 and OTP 23.

If it helps I'm using elixir-lsp version 0.5.0, Vim 8.2 and the latest CoC.

@sashaafm Can you try upgrading the version of rebar3 that you're using in that installation? It just helped me fix a similar issue compiling telemetry:

After upgrading from rebar3 version 3.6.1 to 3.13.1 it compiled successfully.

@axelson I upgraded to the most recent version but I'm still getting the same issue ☹️

@sashaafm did you try to clean any local folder in the repository ? also did you tried the suggested command line to update the deps? There is an issue with older version of rebar3 and hex.pm to retrieve latest packages.

[benoitc]

bump. @sashaafm did you try what I'm describing above?

[benoitc]

no answer since awhile. closing the issue then.
