unknown command: mix. Perhaps you have to reshim?

[soltex1]

Describe the Bug

I got an error unknown command: mix. Perhaps you have to reshim? after installing elixir and erlang, and running mix.

I have added asdf reshim and the absolute path of mix (/home/user/.asdf/shims/mix), and it didn't solve the issue.

Steps to Reproduce

run the following shell script on ubuntu 18.04:

#!/bin/bash
set -e

export DEBIAN_FRONTEND=noninteractive

cd /tmp

# Install asdf - language/tools version manager
git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.10.2

. $HOME/.asdf/asdf.sh
. $HOME/.asdf/completions/asdf.bash

echo -e '\n. $HOME/.asdf/asdf.sh' >> ~/.bashrc
echo -e '\n. $HOME/.asdf/completions/asdf.bash' >> ~/.bashrc

asdf plugin add erlang
asdf plugin add elixir
asdf install erlang 21.3.2
asdf global erlang 21.3.2
asdf install elixir 1.8.1
asdf global elixir 1.8.1

asdf reshim

# Get the application code
git clone ...
cd /tmp/app

# Install dependencies
export HOME=/tmp/app
mix local.hex --force
mix local.rebar --force
mix deps.get --force

....

Expected Behaviour

be able to use mix without any errors

Actual Behaviour

I got an error: unknown command: mix. Perhaps you have to reshim?

Environment

ASDF VERSION:

ASDF ENVIRONMENT VARIABLES:
ASDF_DIR=/home/ssm-user/.asdf

ASDF INSTALLED PLUGINS:

asdf plugins affected (if relevant)

elixir and erlang

Manually downloading kerl as you are doing should not be necessary. Can you explain why you are doing that?

Also, overriding $HOME as you are doing and not setting $ASDF_DIR is likely causing the problem. I'd suggest not changing $HOME unless necessary.

Moved to the elixir plugin as this doesn't seem to an issue with asdf core.

I am manually downloading kerl because I had an error once where kerl wasn't found. I will remove that.

I really need to override $HOME as it fixes an issue with elixir.

I tried to set all these env vars ASDF_CONFIG_FILE, ASDF_DATA_DIR, and ASDF_DIR as this:

export ASDF_CONFIG_FILE=~/.asdf
export ASDF_DATA_DIR=~/.asdf
export ASDF_DIR=~/.asdf

And now I am getting another error after I run mix: No version is set for command mix.

What else should I try?

[Stratus3D]

Did you verify elixir is installed with asdf current? And if so, what does type -a mix print?

[soltex1]

@Stratus3D Yes, elixir is installed, and type -a mix returns mix is /root/.asdf/shims/mix.

I have added these 2 lines (again) before running any mix command and after overriding the $HOME and it worked:

asdf global erlang 21.3.2
asdf global elixir 1.8.1

[soltex1]

@Stratus3D As soon as I override the HOME env var, asdf tries to find the .tool-versions at HOME instead of using the ASDF_DIR. How do I change the .tool-versions path?

I've the same problem, it's actually kind of interesting.
