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

据我所知，Rumbl.Auth.init控制器文件中存在auth.ex函数，我不确定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的问题。

5 个答案:

答案 0 :(得分：18)

我认为你应该尝试清理deps，然后在上传之前再次编译

所以试试

mix deps.clean --all
mix deps.get
mix deps.compile
mix phoenix.server
祝你好运

答案 1 :(得分：8)

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

中输了错字 
import Comeonin.Bcypt, only: [checkpw: 2]

应该是

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

答案 2 :(得分：1)

您也可以删除_build目录并使用mix phoenix.server（Phoenix 1.2）或mix phx.server（Phoenix 1.3）重新启动服务器。

这样做将首次从头开始获取所有依赖项。我更喜欢这种方法，因为我不需要输入一堆命令，我只需要删除一个目录并在我的终端上重新运行最近的命令..这是mix phx.server。是的，我懒惰。

祝你好运。

答案 3 :(得分：0)

在我的情况下发生此错误是因为我意外地在test目录而不是lib目录中创建了一个模块。将其移至lib目录修复它。

答案 4 :(得分：0)

在我的总括项目中，我在support目录中添加了一个新的tests目录，并且测试中无法访问其中的.ex模块。

默认情况下，混合仅在lib目录中查找要编译的文件。您可以通过在project中将elixirc_paths添加到mix.exs来添加另一个目录。
