在更新到我的系统之后 - MAC,我的凤凰应用程序编译得很好,但是无论何时我遇到任何路线都会抛出此错误。

  

服务器:localhost:4000(http)请求:GET /   **(退出)引发了异常:       **(UndefinedFunctionError)函数:crypto.rand_bytes / 1未定义或私有。你的意思是:

  * rand_seed/0
  * rand_seed/1

    (crypto) :crypto.rand_bytes(20)

如@mudasobwa的评论中所述

  

{:plug, "~> 1.3"}文件中加上明确的mix.ex

解决了这个问题。

:crypto.rand_bytes/1removed in OTP 20。您应该使用:crypto.strong_rand_bytes/1代替。

在这种情况下,您似乎需要更新插件才能拥有this commit。您可以运行mix deps.update plug来执行此操作。
