Phoenix错误:模块未加载/不可用

我正在关注编程凤凰书,正在编写实现登录/注销经过身份验证的用户的部分,并且收到错误我不知道该怎么做:

我检查过并仔细检查了我的代码,但看不到任何内容.
我的项目文件在这里:https://github.com/bordeltabernacle/learning-phoenix/tree/master/rumbl

据我所知,Rumbl.Auth.init函数存在于auth.ex控制器文件中,我不确定该Rumbl.Router.Helpers文件是什么或如何加载它.当我删除router.ex文件中唯一的新行时,由于应用程序正在运行,我得到了同样的错误.
我恐怕还不够了解自己.

我认为你应该尝试清理deps,然后在上传之前再次进行编译

所以试试吧

mix deps.clean --all
mix deps.get
mix deps.compile
mix phoenix.server

祝好运

你有错字 https://github.com/bordeltabernacle/learning-phoenix/blob/master/rumbl/web/controllers/auth.ex

import Comeonin.Bcypt, only: [checkpw: 2]

应该

import Comeonin.Bcrypt, only: [checkpw: 2]
