Instructions to run Elixir on Android

bitli

In case this is handy for other people, here is how you can run Elixir on Android:

Install https://termux.com/
apt update; apt upgrade to have your system up to date.
Install Erlang with apt install erlang, you should be able to run erl.
(check if an Elixir package was created so you can avoid the trouble of the remaining lines )
Install wget with apt install wget (otherwise you will get bad address on any wget request).
Create a directory, and cd to it, for example: mkdir elixir; cd elixir.
Download the precompiled package from the link named Precompiled.zip file for the latest release in the page http://elixir-lang.org/install.html#precompiled-package.At time of this writing the command wget https://github.com/elixir-lang/elixir/releases/download/v1.4.2/Precompiled.zip should do this.
Unzip the files with unzip Precompiled.zip.
Go to directory bin.
Download the file termux-fix-shebang from the source at https://raw.githubusercontent.com/termux/termux-packages/master/packages/termux-tools/termux-fix-shebang. You can use wget https://raw.githubusercontent.com/termux/termux-packages/master/packages/termux-tools/termux-fix-shebang.
Execute sh termux-fix-shebang elixir iex elixircin the bin directory (sh is required as the path of the shebang of the script is not compatible with termux).
Execute which env and edit the first line of mix to set the path of command envto the one found by the command which.
Add export PATH=$PATH:$HOME/elixir/bin to your .bashrc or execute the command on your terminal.
You can then mix and iex. An Android phone is not exactly a convenient development platform, but it was useful to me to learn Elixir when waiting for whatever.

Termux is awesome, but you might inform at the top of the post that this is the guide only for Android 5.0 and above. Thanks for the guide!

Thanks for that!
When I apt install wget, Im asked to validate with [Y/n].
If I press y or Y:
No command y found, did you mean Command [ from package coreutils, Command k from package kona etc.
And pressing Enter directly does nothing
Any idea please?

Please try apt install --yes wget, for the older interface to apt, that meant to not ask but assume the operator knows what he is doing and install/remove everything. Can’t check though if it is still valid on the new interface which is used by termux.

Can you copy and paste or screenshot the exact error message you get? Can you also show the output of ls -lah ~/.mix?

That looks correct. And the error message?

this is the error
sh: 1: /data/data/com.termux/files/home/.mix/rebar3: not found
** (Mix) Could not compile dependency :ranch, “/data/data/com.termux/files/home/.mix/rebar3 bare compile --paths “/data/data/com.termux/files/home/hello/_build/dev/lib/*/ebin”” command failed. You can recompile this dependency with “mix deps.compile ranch”, update it with “mix deps.update ranch” or clean it with “mix deps.clean ranch”
