Runtime error while compiling Phoenix: "error parsing file ".../OTP-PUB-KEY.hrl, got: {:error, :enoent}"

I truncated the error message in the title to save space. The full error message is below:

==> phoenix
Compiling 67 files (.ex)

== Compilation error in file lib/mix/tasks/phx.gen.cert.ex ==
** (RuntimeError) error parsing file /usr/lib/erlang/lib/public_key-1.6.7/include/OTP-PUB-KEY.hrl, got: {:error, :enoent}

could not compile dependency :phoenix, "mix compile" failed. You can recompile this dependency with "mix deps.compile phoenix", update it with "mix deps.update phoenix" or clean it with "mix deps.clean phoenix"

I’m new to Elixir/Phoenix but I know that :enoent means that the file couldn’t be found. Correct me if I’m wrong but it seems like the OTP-PUB-KEY.hrl file from my erlang library is missing…? I tried searching for information on that file (looks like an RSA public key) but I couldn’t find much that seemed to help with this issue. Any help/suggestions would be really appreciated.

What is your erlang version? This is strange because in my 21.3.8 otp the public_key has a 1.6.6 version. Also ls /usr/lib/erlang/lib/ might help

I’m running Erlang/OTP 22:

Erlang/OTP 22 [erts-10.4] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1]

ls /usr/lib/erlang/lib/ ?

How did you install erlang?

Here’s what I get when I run ls /usr/lib/erlang/lib/:

I installed Erlang via the Ubuntu Elixir 1.8.2 package from the Erlang website (which included Erlang 22 as well).

Just in case:

ls /usr/lib/erlang/lib/public_key-1.6.7/include/

May be you have no read rights from this file?

8

That might be the case:

ls: cannot access '/usr/lib/erlang/lib/public_key-1.6.7/include/': No such file or directory

If that is the issue, is there a way to grant myself read rights?

)) Just one last try:

ls /usr/lib/erlang/lib/public_key-1.6.7/

That got us something:

It’s got just the one directory, ebin:

So certainly not the include directory that the compiler seems to be looking for and the public key is a .beam file.

Looks like you have invalid/incomplete installation

I recomment you two options:

  1. Reinstall erlang

  2. Use asdf with asdf-erlang and asdf-elixir which allows you to have different versions of erlang and elixir for different projects

Personally I prefer an asdf

Reinstalling did the trick. Thanks for the help!

On a fresh debian bullseye install , sudo apt install erlang-dev did the trick

On a fresh ubuntu install, there was a public_key-1.13 but no public_key-1.6.7. I created a symlink, and so far it works…
