Some paths fail with argument error nofile about contex-samples

Agree! I tried on 3 different PCs running MacOS, Windows & Linux.

What version of Erlang & Elixir do you have installed?

[tanguilp]

$ asdf current
elixir         1.9      (set by /home/tangui/.tool-versions)
erlang         21.0     (set by /home/tangui/.tool-versions)
nodejs         13.5.0   (set by /home/tangui/.tool-versions)

[mindok]

Could you try running something like this in iex:
:erlang.float_to_binary(12.5, [:compact, decimals: 0])

If that fails then I think you have some issue with your installation as that's erlang kernel code - from http://erlang.org/doc/man/erlang.html#float_to_binary-2

[tanguilp]

$ pwd
/tmp/contex-samples

$ iex -S mix phx.server
Erlang/OTP 21 [erts-10.0] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe]

Cannot reproduce with:

$ asdf current
elixir         1.9.0    (set by /home/home/.tool-versions)
erlang         22.1 (set by /home/home/.tool-versions)

on another computer. May be a local problem, I suggest we close this issue, and reopen it later if needed.
