Latest update appears to break asdf install

[dobs]

Example .tool-versions contents:

erlang 22.1
elixir 1.9.4-otp-22

We're seeing reproduce-able failures in a project where Elixir previously installed successfully by running:

asdf uninstall elixir 1.9.4-otp-22
asdf plugin-update elixir
asdf install

Locally the failures look like:

erlang 22.1 is already installed
==> Checking whether specified Elixir release exists...
==> Downloading 1.9.4-otp-22 to /var/folders/8t/bcy9yfg90c56_4m_36wmtyrm0000gp/T//elixir-precompiled-1.9.4-otp-22.zip

you might want to add one of the following in your .tool-versions file:

elixir 1.6.1
elixir 1.6.5
elixir 1.6.6
elixir 1.7.3
elixir 1.7.4-otp-21
elixir v1.6.1
elixir v1.7.4
elixir 1.7.3-otp-21
elixir 1.9.1
elixir 1.8

elixir 1.8

And on CircleCI:

==> Copying release into place
/usr/bin/env: 'elixir': No such file or directory
/usr/bin/env: 'elixir': No such file or directory

My current hunch is that this relates to the double mix lines here, as it would explain the duplicate error messages: e7e9e5d#diff-81fd2adb13518cfcf88c004b912c4d9fR22

I manually installed elixir this way:

• extract the zip folder listed in the output from the temp folder (here /var/folders/8t/bcy9yfg90c56_4m_36wmtyrm0000gp/T//elixir-precompiled-1.9.4-otp-22.zip)
• copy its content to ~/.asdf/installs/elixir/1.9.4-otp-22 (with the folder name being the version you were trying to install)
• run cp ~/.asdf/shims/erlang ~/.asdf/shims/elixir
• edit ~/.asdf/shims/elixir and replace erlang with elixir -- I also updated the comment with the version (not sure it's parsed)
• run cp ~/.asdf/shims/elixir ~/.asdf/shims/mix
• edit ~/.asdf/shims/mix and replace elixir with mix

Now you should have mix and elixir available.
You can do mix local.hex and mix local.rebar to be ready to go.

This is also breaking our CI pipeline, is there a way to install the previous commit with ASDF? (Apart from forking and manually reverting the commit)

[eamontaaffe]

@dvic it looks like you are unable to select a version for the plugins: asdf-vm/asdf#166

This is breaking our CI pipeline too 😢.

[sneako]

Also seeing this behaviour, but I was able to successfully install after checking out the last commit before yesterday's release:

cd ~/.asdf/plugins/elixir
git checkout 254fec762111c89f11a947d15f4d7af24f80efab

[dobs]

@dvic We've forked for the time being, but adding a line like the one @sneako provided to your CI steps should also work as a temporary workaround.

Making the git ref a CI parameter (defaulting to master) might be a good future-proofing step.

[dvic]

@sneako @dobs nice workaround, easier than forking, will use that, thanks!

Quick followup, the revert PR has been accepted so things should be working again.
