Unable to run pre hooks for 'compile', command 'erl_vsn' not found. in 3.1.0

Hi guys,

I'm trying to upgrade from 3.0 to 3.1, but I'm getting the following error on both my dev machine and in CI:

===> Fetching rebar_erl_vsn ({pkg,<<"rebar_erl_vsn">>,<<"0.1.7">>})
===> Downloaded package, caching at /home/john/.cache/rebar3/hex/default/packages/rebar_erl_vsn-0.1.7.tar
===> Compiling rebar_erl_vsn
===> Compiling elli
===> Unable to run pre hooks for 'compile', command 'erl_vsn' not found.
** (Mix) Could not compile dependency :elli, "/home/john/.asdf/installs/elixir/1.6.3/.mix/rebar3 bare compile --paths "/home/john/code/hc/dylan/_build/test/lib/*/ebin"" command failed. You can recompile this dependency with "mix deps.compile elli", update it with "mix deps.update elli" or clean it with "mix deps.clean elli"

It seems that since 3.0, rebar_erl_vsn was added to rebar.config, could this be the source of the issue?

I'm running Erlang 20.3.6 and Elixir 1.6.3.

Hi friends, any update here? It'd be great to use the latest Elli

Looks like maybe a Mix issue to me. As a workaround could override the elli hooks in your rebar.config.

The above issue is closed, does that mean this is fixed?

@lpil I believe so, but you'll need to ensure you're running rebar3 v 3.6.0 or higher.

• https://github.com/erlang/rebar3/releases/tag/3.6.0
• run compile provider in default namespace from bare erlang/rebar3#1810

It works! Shall we close this?

@johnhamelink ?

FWIW, John and I work together at Honeycomb TV, we've resolved the issue in the projects in question :)
