Elixir“在注册表中找不到软件包：：hackney”问题

Question

我正在尝试将覆盖范围添加到我的项目中，但是不断遇到问题。

我尝试了错误中的所有建议此列表底部的消息。

我有一个大型项目，希望增加覆盖范围进行单元测试，但所有保险范围内的炸弹同样。

我用only混合了deps（）开始了一个干净的项目“ bug”另外，以使干扰最小化。

任何帮助将不胜感激。

版本：

rebar3 --version
rebar 3.13.2 on Erlang/OTP 22 Erts 10.4.3

elixir --version
Erlang/OTP 22 [erts-10.4.3] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [hipe]
Elixir 1.9.4 (compiled with Erlang/OTP 22)

erl --version
Erlang/OTP 22 [erts-10.4.3] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [hipe]
Eshell V10.4.3  (abort with ^G)

deps中的mix.exs

defp deps() do
  [
    #{:coverex, "~> 1.5", only: [:test], runtime: false},
    {:excoveralls, "~> 0.13.0", only: [:test], runtime: false},
    {:idna, "~> 6.0.1"},
  ]
end

我使用了不同版本的Coverex和Excoveralls，但结果是相同的。

我注意到：

"Bad dependency version for httpoison (and others...)"

但是我也不知道该怎么办。

错误/警告消息似乎与依赖项有关。依赖关系不应该自己解决吗？

这样做：

rm -rf〜/ .cache / rebar3〜/ .mix deps _build mix deps.get

十六进制会告诉您是否有新版本可用，据我所知，通过mix local安装和使用的rebar版本。rebar由您使用的mix（solixer）版本决定。它受exact版本匹配的限制，而不是（语义）范围的限制。

因此，当十六进制告诉您可以在mix deps.get之后进行更新时，最好运行mix local.hex，而您应该在每次更新长生不老药之后运行mix local.rebar。

每周执行一次。某种与依赖性有关的棘手错误……
