入门：使用`mix deps.get`安装后无法在elixir shell中运行功能

Question

我正在按照自述文件中的指示将mint与mint一起安装。但是，当我尝试执行示例代码时，出现错误：

hex

由于我是Exixir的初学者，所以我确定我已经错过了一些简单的事情。这是我的安装方式：

---

在docker中运行：

iex(1)> {:ok, conn} = Mint.HTTP.connect(:http, "httpbin.org", 80)
** (UndefinedFunctionError) function Mint.HTTP.connect/3 is undefined (module Mint.HTTP is not available)
    Mint.HTTP.connect(:http, "httpbin.org", 80)

创建新项目：

docker run -it --rm  elixir /bin/sh

编辑

# mix new kv
* creating README.md
* creating .formatter.exs
* creating .gitignore
* creating mix.exs
* creating lib
* creating lib/kv.ex
* creating test
* creating test/test_helper.exs
* creating test/kv_test.exs

Your Mix project was created successfully.
You can use "mix" to compile it, test it, and more:

    cd kv
    mix test

Run "mix help" for more commands.

，因此kv/mix.exs块现在看起来像：

deps

更改目录并运行安装，选择

  defp deps do
    [
      # {:dep_from_hexpm, "~> 0.3.0"},
      # {:dep_from_git, git: "https://github.com/elixir-lang/my_dep.git", tag: "0.1.0"}
      {:castore, "~> 0.1.0"},
      {:mint, "~> 0.4.0"}
    ]
  end

以安装Y：

hex

这似乎有效。我也可以运行测试：

9afa01708fef# cd kv
9afa01708fef# mix deps.get
Could not find Hex, which is needed to build dependency :castore
Shall I install Hex? (if running non-interactively, use "mix local.hex --force") [Yn] Y
* creating /root/.mix/archives/hex-0.20.1
Resolving Hex dependencies...
Dependency resolution completed:
New:
  castore 0.1.3
  mint 0.4.0
* Getting castore (Hex package)
* Getting mint (Hex package)

然后运行外壳程序：

9afa01708fef# mix test
==> castore
Compiling 1 file (.ex)
Generated castore app
==> mint
Compiling 1 file (.erl)
Compiling 22 files (.ex)
Generated mint app
==> kv
Compiling 1 file (.ex)
Generated kv app
..

在那一点上我运行

9afa01708fef# iex  
Erlang/OTP 22 [erts-10.5] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:1] [hipe]

（如该问题顶部的方框中的。）>

我在这里错过了什么？

我正在按照自述文件中的指示安装带有十六进制的薄荷。但是，当我尝试执行示例代码时，出现错误：iex（1）> {：ok，conn} = Mint.HTTP.connect（：http，“ httpbin.org”，80）** ...

对不起，我。解决方案是使用以下命令启动外壳：
