Failed to compile 1.16

[ilkka]

I just came back to one repo after a few weeks of not doing anything, and I noticed that I couldn't compile it any more. This is what I was seeing doing mix deps.compile with DEBUG=1:

** (Mix) Could not compile dependency :hackney, "escript.exe "c:/Users/Ilkka/.mix/rebar3" bare compile --paths="c:/Users/Ilkka/Code/my-project/_build/dev/lib/*/ebin"" command failed. You can recompile this dependency with "mix deps.compile hackney", update it with "mix deps.update hackney" or clean it with "mix deps.clean hackney"

I'm getting hackney as a dependency of timex, which depends on ~> 1.0. I added my own dependency to {:hackney, "== 1.15.2"} and that completely fixed the issue for me

I'm on Win 10 and elixir --version output is

Erlang/OTP 23 [erts-11.0] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1]

Elixir 1.10.3 (compiled with Erlang/OTP 21)

I suffered the same issue (on MacOS) and @ilkka 's solution worked for me also.

Here's a minimal example that has the problem: https://github.com/ilkka/hackney_compile_test

All I did was mix new followed by adding the Hackney dep, and mix deps.compile fails.

Hrm so did you try rather to add mix as dep to your app? I think mix need to be updated. I got the same issue until I upgraded rebar3 and I wonder if something changed in hex or such. Let me know.

I was getting compilation errors too on Macos (fine on Linux/CI). Had to re-install/update rebar via mix local.rebar, and everything compiles now.

@ashutoshrishi 's procedure fixed it for me as well. Man, I wish there had been even a tiny indication somewhere in there about something being somehow out of date (I guess?).
