ex_cldr is not compiling with Elixir 1.7.2

[glafontant]

I ran mix deps.get per the installation docs. I opted to go with the manual process rather than Docker. The only hex package not to compile for the phoenix app is ex_cldr. I received the following compilation error

could not compile dependency :ex_cldr, "mix compile" failed. You can recompile this dependency with "mix deps.compile ex_cldr", update it with "mix deps.update ex_cldr" or clean it with "mix deps.clean ex_cldr"

Here is output from mix hex.info

Hex:    0.20.5
Elixir: 1.7.2
OTP:    22.0.7

Researching this error it appear to occur when a machine has 2 different versions of Elixir installed. I have two versions of Elixir as I have 1.9.1 as my default and 1.7.2 for this application. To resolve this error I ran the following commands.

mix clean; mix deps.clean --all; rm -rf _build

Ran mix deps.get and did not see the error. Unfortunately when I tried to create the DB by running mix ecto.create. The same compilation error returned. Has any seen this error or any tips how to manage hex dependancies with 2 versions of Elixir? Is there a version of RVM or RBENV for Elixir? Thank you.

Hi,

I'm also getting the same issue in mix ecto.create.

@glafontant Did you manage to get this issue resolved?
