Phoenix开始抛出(UndefinedFunctionError)函数:crypto.rand_bytes/1未定义或私有

Question

在更新到我的系统 - MAC之后,我的凤凰应用程序编译得很好但是在我遇到任何路由时都会抛出此错误.

服务器:localhost:4000(http)请求:GET/**(退出)引发异常:**(UndefinedFunctionError)函数:crypto.rand_bytes/1未定义或私有.你是说其中一个:

  * 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

如果你们需要任何其他信息,请告诉我.

Answer 1

正如@mudasobwa的评论中提到的那样

{:plug, "~> 1.3"}在您的mix.ex文件中明确说明.

解决了这个问题.

谢谢所有试图提供帮助的人.

Answer 2

:crypto.rand_bytes/1在OTP 20中删除.你应该使用:crypto.strong_rand_bytes/1代替.

在这种情况下,您似乎需要更新插件以进行此提交.你可以跑来mix deps.update plug做这件事.
