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:

如@mudasobwa的评论中所述
在
{:plug, "~> 1.3"}
文件中加上明确的mix.ex
。
解决了这个问题。
感谢所有试图提供帮助的人。

:crypto.rand_bytes/1
是removed 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。
