Compilation fails with undefined function erlang:get_stacktrace/0

[sezaru]

Environment

• Elixir & Erlang/OTP versions (elixir --version):

Erlang/OTP 24 [erts-12.0.2] [source] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1] [jit]

Elixir 1.12.0 (compiled with Erlang/OTP 24)

• Operating system:
  Ubuntu 20.04

Current behavior

Compiling a code that depends on sleeplocks which in case depends on rebar3_hex fails with the following error with new OTP 24:

===> Fetching rebar3_hex v6.11.4
===> Version cached at /home/sezdocs/.cache/rebar3/hex/hexpm/packages/rebar3_hex-6.11.4.tar is up to date, reusing it

** (Mix) Could not compile dependency :sleeplocks, "/home/sezdocs/.mix/rebar3 bare compile --paths /home/sezdocs/project/endpoints/_build/dev/lib/*/ebin" command failed. You can recompile this dependency with "mix deps.compile sleeplocks", update it with "mix deps.update sleeplocks" or clean it with "mix deps.clean sleeplocks"

I tried this with both Elixir 1.12.1 and 1.12.0, and also OTP 24.0.1 and 24.0.2.

Please run mix local.rebar to update your Rebar installation. Or if you have Rebar3 locally installed (which rebar3 will tell you the location), then update it too. This issue is cause by an incompatible Rebar version with Erlang OTP 24.

[sezaru]

Unfortunately, that didn't work, I think I already have the latest version (6.11.4).

This is the output of the command anyway:

$ mix local.rebar
/home/sezdocs/.mix/rebar already exists, overwrite? [Yn] Y
* creating /home/sezdocs/.mix/rebar

/home/sezdocs/.mix/rebar3 already exists, overwrite? [Yn] Y
* creating /home/sezdocs/.mix/rebar3

I don't know why, but changing my HEX_MIRROR fixed it.

What I did was the following:

HEX_MIRROR=https://cdn.jsdelivr.net/hex mix local.hex
HEX_MIRROR=https://cdn.jsdelivr.net/hex mix local.rebar

“ 6.11.4” is not a valid Rebar version but glad it was addressed. This is not an Elixir issue after all, just outdated Rebar.

the same happens inside docker, using the image hexpm/elixir:1.12.1-erlang-24.0.2-alpine-3.13.3

docker run -it hexpm/elixir:1.12.1-erlang-24.0.2-alpine-3.13.3 sh

It installs version 3.13.3 by default

/ # mix local.rebar
/ # ~/.mix/rebar3 --version
rebar 3.13.3 on Erlang/OTP 24 Erts 12.0.2

But using the jsdelvr cdn, it installs 3.15.1

/ # HEX_MIRROR=https://cdn.jsdelivr.net/hex mix local.rebar
/ # ~/.mix/rebar3 --version
rebar 3.15.1 on Erlang/OTP 24 Erts 12.0.2

At this point i'm not even sure where I can report this, or where the issue is. Any pointer?

[josevalim]

Ok, I can reproduce it. It seems Hex is returning the wrong Rebar but the mirror is using a cache with the correct answer. This is a regression on the server, we are investigating. Thanks!

[josevalim]

Fixed, thanks!

Doesn't appear fixed for me.

My Elixir version is:

Erlang/OTP 24 [erts-12.0] [source] [64-bit] [smp:32:32] [ds:32:32:10] [async-threads:1] [jit]

Elixir 1.11.3 (compiled with Erlang/OTP 23)

I tried running mix local.rebar, removing ~/.mix/ and ~/.cache/rebar3 and installing rebar again, removing project build and deps files, using the jsdelivr cdn, but I still get this error:

===> Fetching rebar3_hex v6.11.4

You can recompile this dependency with "mix deps.compile sleeplocks", update it with "mix deps.update sleeplocks" or clean it with "mix deps.clean sleeplocks"

What am I doing wrong?

[josevalim]

@rinpatch just to be sure, what does which rebar3 return? Also, what does ~/.mix/rebar3 --version return? Finally, if you are using asdf, remember you need to rehash the paths or similar after you install rebar3.

hi hi i'm having the same issue as @rinpatch
ss1: using mix local.rebar
ss2: using HEX_MIRROR=https://cdn.jsdelivr.net/hex mix local.rebar
