Phoenix: Could not compile dependency :ranch

Stack Overflow discussion

FYI: just tried this and ranch compiles without error:

$ docker pull ubuntu:19.04
$ docker run -ti --rm ubuntu:19.04 /bin/bash
# cat /etc/lsb-release
# apt update
# apt install git
# git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.7.2
# echo -e '\n. $HOME/.asdf/asdf.sh' >> ~/.bashrc
# echo -e '\n. $HOME/.asdf/completions/asdf.bash' >> ~/.bashrc
# . ~/.bashrc
# apt-get -y install build-essential autoconf m4 libncurses5-dev libwxgtk3.0-dev libgl1-mesa-dev libglu1-mesa-dev libpng-dev libssh-dev unixodbc-dev xsltproc fop

# asdf plugin-add elixir https://github.com/asdf-vm/asdf-elixir.git

# mix local.hex
# mix archive.install hex phx_new 1.4.6
# mix phx.new my_app --no-ecto
# cd my_app
# mix phx.server

To become functional the above is still missing:

• setting to a UTF-8 locale (default is POSIX)
• installing node.js

But at least it doesn’t seem to be some Ubuntu 19.04 weirdness.

I do find the leading space in Command ’ OTP’ not found a bit strange but I have no idea where that comes from.

Yea.. it looks like rebar3 is saying it failed to run the command rebar3 bare OTP. No idea where that would be coming from.

It fails when running the command mix archive.install hex phx_new 1.4.6.

I am out of ideas by now …

There are the usual suspects:

$ mix archive
  * hex-0.19.0
  * phx_new-1.4.6
$ mix archive.uninstall phx_new-1.4.6
$ mix archive.uninstall hex-0.19.0
$ mix archive
  No archives currently installed.
$ mix local.hex
$ mix archive.install hex phx_new 1.4.6

I presume this trouble only started once you tried to do anything with Phoenix?

Before that you had been using Elixir/Mix on this installation for a while?

How did you know to install all that stuff?

Various sources. e.g.:

• elixirgirls.com — Domain For Sale for $2,788 | Unstoppable Domains
• docker-asdf-elixir/Dockerfile at master · timefairy/docker-asdf-elixir · GitHub

I should have trimmed the GUI libs and included apt-utils, locales and inotify-tools.

Basically experiment and adjust when something is missing …

The issues started once I started trying to use Phoenix via the mix phx.server command.
This is a fresh project created with mix phx.new my_app_name --no-ecto. Running mix deps.get and any other mix command works without issue.

I have also run the commands you specified, but the issue remains the same.

have you tried mix deps.clean --all and then mix deps.get ?

Yes, the error remains.

I just found out what the error was.

Upon reviewing this comment it got me thinking …

This is the absolute path of the project:

/home/user/Workspace/Functional Web Development with Elixir, OTP, and Phoenix/islands_interface

Turns out, phx.server errors out because it is inside the folder Functional Web Development with Elixir, OTP, and Phoenix/. Turns out that space in ’ OTP’ is from the folder’s name.

To prove my theory I created a project called test under /home/user/Workspace/. Everything worked perfectly.
This proves that the issue here is the path, more specifically, the folder’s name. The conclusion I draw from here is that you can’t have a folder whose name has spaces and with the word “OTP” in it, or else rebar (and for some reason, ranch) won’t work.

Is this a bug? Should I report this behavior somewhere?
