升级Elixir后，“Phoenix.HTML.Engine.init / 1未定义或私有”和“Plug.Conn .__ struct __ / 1未定义”等错误

Question

我升级到Elixir 1.3。当我尝试使用mix phoenix.server启动我的Phoenix应用时出现错误：

== Compilation error on file web/views/page_view.ex ==
** (UndefinedFunctionError) function Phoenix.HTML.Engine.init/1 is undefined or private

尝试通过升级lib来修复它，我遇到了其他错误：

** (CompileError) lib/poison/parser.ex:11: Poison.SyntaxError.__struct__/1 is undefined, cannot expand struct Poison.SyntaxError

和

== Compilation error on file lib/plug/test.ex ==
** (CompileError) lib/plug/test.ex:53: Plug.Conn.__struct__/1 is undefined, cannot expand struct Plug.Conn
    (stdlib) lists.erl:1353: :lists.mapfoldl/3

有什么想法吗？

Answer 1

似乎为我修复的是迫使依赖项重新编译：

mix deps.compile --force

如果在尝试运行测试时遇到错误，请尝试：

MIX_ENV=test mix deps.compile --force
