Elixir：mix deps.get 请求失败（403）并且没有缓存副本

Question

I am attempting to start using ratatouille in a project. This is, I believe, the latest version of rataouille from github.

I started a new project for my learnings:

mix new rata_count

In the ratatouille installation instructions I use the deps:

  defp deps do
    [{:ratatouille, "~> 0.5.0"} ]
  end

Other than this deps code, the rest of mix.exs is as generated with "mix new rata_count". I have added no additional code to this project.

mix deps.get responds:

mix deps.get
Resolving Hex dependencies...
Dependency resolution completed:
New:
  asciichart 1.0.0
  elixir_make 0.6.0
  ex_termbox 1.0.1
  ratatouille 0.5.0
* Updating ratatouille (Hex package)
* Getting ex_termbox (Hex package)
Request failed (403)
** (Mix) Package fetch failed and no cached copy available (https://repo.hex.pm/tarballs/ex_termbox-1.0.1.tar)

A search reveals nothing for this error.

I was able to compile and run the github examples of ratatouille. All the examples worked as specified. Now I cannot seem to use rataouille in my projects.

My system is Centos 7, elixir 1.9.4, Erlang/OTP 22 [erts-1-.4.3] 64 bits.

How do I resolve this error? Should I create a cached version? How do I create a cached version?

Is hex down?

https://hex.pm/packages/ex_termbox has:

Delete your mix.lock file (which has, presumably, chosen to pin 1.0.1).

Alternatively, your top-level project should specify an exact version of ex_termbox :

  defp deps do
    [
      {:ratatouille, "~> 0.5.0"},
      {:ex_termbox, "1.0.0"}
    ]
  end

...and then delete mix.lock and the deps directory, before running mix deps.get again.

Answer 2

I ran into this issue as well and nothing I tried fixed it. A day later, I tried running mix deps.get again and had no problems. So it may just be a server-side issue.

Answer 3

Roger Lipscombe suggested I use the top level mix.exs deps as:

  defp deps do
    [{:ratatouille, "~> 0.5.0"}, {:ex_termbox, "1.0.0"}]
  end

This worked.

I noticed that deps/ratatouille/mix.exs also used a dependency of {:ex_termbox, "1.0"}. I don't understand why ratatouille could not find this, but I can now proceed.

Thank you Roger for your advice and timely replies. :)
