请对此帮助。我的系统确实安装了Elixir版本1.3，并且我使用的是asdf。

这是mix.exs文件https://pastebin.com/wd9jPGdq

您可以在混合文件中降级down剂要求，然后尝试再次编译。在您的mix.exs文件中，更改：

...
version: "0.1.0",
elixir: "~> 1.6",
start_permanent: Mix.env() == :prod,
...

收件人

...
version: "0.1.0",
elixir: "~> 1.3",
start_permanent: Mix.env() == :prod,
...

然后在您的终端中运行以下命令：

mix do clean, deps.clean --all
mix deps.get
mix compile

或者，您可以升级计算机中安装的elixir版本。
