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.
Check your OTP version and the version of elixir, especially which OTP version was used to compile it.
Both OTP versions need to be either greater than or equal to 21 or lesser than that. It’s not allowed to have one at 21 and one at 20.
My guess is that you have installed a current OTP and also are using a precompiled elixir version. Those are compiled with OTP 19 as far as I remember.
I have updated the original post with more information about the error. I am sure the PLT tables are not being built correctly, but at this point I have no idea on how to fix it.
After a long time of waiting, it finally finished, but now I have the following warnings/errors:

PLT is up to date!
No :ignore_warnings opt specified in mix.exs and default does not exist.

Am I missing some config flag?
I am using the {:dialyxir, "~> 1.0.0-rc.4", only: [:dev], runtime: false}, perhaps it is not stable enough?
Please try again with master, if the error remains please file a bug report at https://github.com/jeremyjh/dialyxir/issues and use one of the older RCs until the issue has been resolved and a new release (candidate) is available.
@NobbZ Thanks for the input, I have now created issues in the project’s page.
Once ( if ) the issue gets resolved, I will updated this discussion so future readers can also benefit from my findings or in case someone goes through the same.
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).
asdf install erlang 21.1.1
asdf install elixir 1.7.4-otp-21
asdf global erlang 21.1.1
asdf global elixir 1.7.4-otp-21
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/archives and 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.
