透析器无法识别长生不老药功能,错误:0:未知的功能

我的电脑上安装了Elixir1.7.2,使用 asdf ,elixir和erlang otp 21 dialyzer github

{:dialyxir, "~> 1.0.0-rc.3", only: [:dev], runtime: false} 

mix dialyzer

Could not get Core Erlang code for: /home/sigu/.asdf/installs/elixir/1.7.2/lib/elixir/ebin/elixir_parser.beam

Recompile with +debug_info or analyze starting from source code  Could not get Core Erlang code for: /home/sigu/.asdf/installs/elixir/1.7.2/lib/logger/ebin/Elixir.Logger.ErlangHandler.beam

然后所有操作都会失败,并出现错误,包括elixir内置的函数,如 System.get_env/1

:0:unknown_function
Function System.get_env/1 does not exist.
