Failed to start Phoenix App after Elixir 1.3.0 upgrade

Hi,

I have a Phoenix app running fine with Elixir 1.2.x. Upgraded to Elixir 1.3.0 this morning and now failed to compile and run the app :frowning: I tried reps.clean and that didn’t help.

fchan$  mix deps.clean --all && mix deps.update —all
<< All the output from deps.clean and deps.update>>
chan:gauge fchan$ mix phoenix.server

** (Mix) Could not compile dependency :erlware_commons, "/Users/fchan/.mix/rebar3 bare compile --paths         "/Users/fchan/chaos/gauge/_build/dev/lib/*/ebin"" command failed. You can recompile this dependency with "mix     deps.compile erlware_commons", update it with "mix deps.update erlware_commons" or clean it with "mix deps.clean     erlware_commons"
fchan:gauge fchan$

My Erlang, Elixir and Phoenix version

fchan:gauge fchan$ mix phoenix.new -v
Phoenix v1.1.4
fchan:gauge fchan$ mix --version
Erlang/OTP 18 [erts-7.3] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

Mix 1.3.0
fchan:gauge fchan$

Still pretty new to Elixir, Phoenix and Erlang and help is much appreciated.

Thanks

Did you try to fix with rebar3 update ?

thanks for your reply.

Still pretty new to Elixir and Erlang, do I need to install rebar3? or it’s like a task that can be executed with mix ?

Try this

$ mix local.rebar
$ rm -rf deps
$ rm -rf _build
$ mix deps.get

I’m just trying to think something :wink: If you can, could you maybe post your app so we can try to debug it locally? I’m not an expert myself though :wink: Cf is on hex https://hex.pm/packages/cf so it should be downloaded by mix without problems :confused:

This works

fchan:gauge fchan$ mix local.rebar
/Users/fchan/.mix/rebar already exists, overwrite? [Yn] Y
* creating /Users/fchan/.mix/rebar
/Users/fchan/.mix/rebar3 already exists, overwrite? [Yn] Y
* creating /Users/fchan/.mix/rebar3
fchan:gauge fchan$ mix phoenix.server

Thanks a lot for your help :slight_smile:

Can someone shed some light what happened? I’m guessing mix local.rebar force update on Erlang related dependency and hence trigger an upgrade and solve the issue?

Try to upgrade your phoenix app to 1.1.6. Also take a look at this thread.

You probably hit some bug in rebar. When you run mix local.rebar you will update to the latest version of rebar that the elixir team has published.
