elixir - Phoenix 开始抛出 (UndefinedFunctionError) 函数 :crypto. rand_bytes/1 is undefined or private

Question

在更新到我的系统 - MAC 之后，我的 phoenix 应用程序编译得很好，但是每次我遇到任何路线时都会抛出这个错误。

Server: localhost:4000 (http) Request: GET / ** (exit) an exception was raised: ** (UndefinedFunctionError) function :crypto.rand_bytes/1 is undefined or private. Did you mean one of:

  * rand_seed/0
  * rand_seed/1

    (crypto) :crypto.rand_bytes(20)
    (plug) lib/plug/request_id.ex:59: Plug.RequestId.generate_request_id/0
    (plug) lib/plug/request_id.ex:48: Plug.RequestId.get_request_id/2
    (plug) lib/plug/request_id.ex:42: Plug.RequestId.call/2
    (olars) lib/olars/endpoint.ex:1: Olars.Endpoint.phoenix_pipeline/1

    (plug) lib/plug/adapters/cowboy/handler.ex:15: Plug.Adapters.Cowboy.Handler.upgrade/4
    (cowboy) src/cowboy_protocol.erl:442: :cowboy_protocol.execute/4

我的 mix.exs

正如@mudasobwa 在评论中提到的

put an explicit {:plug, "~> 1.3"} in your mix.ex file.

修复了这个问题。
