Background
I am trying dialyxir to find out if it is worth it, however I have a bunch of errors on the compile phase and I want to fix them.
What did you do?
Created a pet project to try out dialyzer with dialyxir.
mix new dialzyer_projectcd dialyzer_project- Install
dialyxirglobally - Added the dialyxir dependency
mix dialyzer
After this, I see a ton of red messages on my screen:

Seems that every possible Erlang package has this issue.
But astonishingly enough, the command still analyses the project and still shows errors. I have installed erlang and elixir using asdf.
Question
How can I fix the compile errors?

Fixed the issue. Turns out I had a lingering version of dialyxir isntalled globally with asdf
elixir 1.7.3-otp-21. I had to go to~/.asdf/installs/elixir/1.7.3-otp-21/.mix/archivesand manually delete the dialyxir folder.Once I did that, everything worked out perfectly. So as a cautionary tale of advise for future readers, never install dialyxr locally and globally.
If you have dialyxir installed globally, make sure none of your projects has a local reference to it, or you will be in for a world of pain.
Special thanks to @NobbZ for helping out with the Git issue.

You need to
asdf local elixir 1.7.3-otp-21.That will get you the Elixir that is precompiled with the correct version of OTP.

Please try again with master, if the error remains please file a bug report at Issues · jeremyjh/dialyxir · GitHub and use one of the older RCs until the issue has been resolved and a new release (candidate) is available.

Thanks for the tip @jeremyjh.
I’ve been struggling with Dialyzer usage and didn’t realise it was because I needed to install the appropriate Elixir/OTP version when using asdf (as below).

Well, except for very few exceptions, do not use
mix archive.installat all.This is why I also PR’d and removed global installation instructions from the README.
