As I'm using Elixir/OTP 20.2.2, I expected to be able to install `elixir 1.6.1-otp-20.2.2`:

$ asdf install elixir 1.6.1-otp-20.2.2
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   243    0   243    0     0    729      0 --:--:-- --:--:-- --:--:--   729
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of /…/elixir-precompiled-1.6.1-otp-20.2.2.zip or
        /…/elixir-precompiled-1.6.1-otp-20.2.2.zip.zip, and cannot find /…/elixir-precompiled-1.6.1-otp-20.2.2.zip.ZIP, period.

Bob seems to build Elixir for every officially supported OTP version, but from [what I can see](https://github.com/hexpm/bob/blob/master/README.md#elixir-builds):

> These builds are available at `https://repo.hex.pm/builds/elixir/{REF}-otp-{OTP_MAJOR_VERSION}.zip` […]

it is only builds precompiled off of the major versions of OTP that are exposed. Installing `elixir 1.6.1-otp-20` worked:

$ asdf install elixir 1.6.1-otp-20
# …
$ elixir --version
Erlang/OTP 20 [erts-9.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:10] [hipe] [kernel-poll:false]

Elixir 1.6.1 (compiled with OTP 20)

Hence, I'm suggesting to replace `-otp-${OTP_VERSION}` by `-otp-${OTP_MAJOR_VERSION}` for improved clarity.

Elixir plugin for asdf version manager


Elixir requires Erlang to be installed. You can use the asdf-erlang plugin to install Erlang versions.

asdf plugin-add elixir https://github.com/asdf-vm/asdf-elixir.git

Elixir precompiled versions

Precompiled Elixir packages are built by Bob whenever a git push or a new release is made at the elixir repo.

These precompiled packages are built against every officially supported OTP version, however if you only specify the elixir version, like 1.4.5, the downloaded binaries will be those compiled against the oldest OTP release supported by that version.

If you would like to use precompiled binaries built with a more recent OTP, you can append -otp-${OTP_MAJOR_VERSION} to any installable version that can be given to asdf-elixir.

So, for example, to install Elixir 1.5.0 and take advantage of the new features from OTP-20 you might install version 1.5.0-otp-20.

Be sure to also install the correspoding Erlang/OTP version with asdf-erlang, and to have both selected versions in your .tool-versions file.

Compiling from a git reference

You can compile your own elixir from a commit reference from the elixir github repository.

.tool-versions file

You can specify the version to install with a line like so in your .tool-versions file:

elixir ref-<commit reference>

Using the CLI

You can install the version using: asdf install elixir ref:<commit reference>.

You can then set the local/global version to your new version with asdf local elixir ref-<commit reference> or asdf global elixir ref-<commit reference>.

Elixir escripts support

This plugin supports elixir escripts adding them to your path just like any other elixir binary. Whenever you install a new escript with mix escript.install you need to asdf reshim elixir in order to create shims for it.


Check asdf readme for instructions on how to install & manage versions of Elixir.
