我刚刚生成了一个新的实时视图应用程序，phx.new --live并且不断收到此错误：

复制信息

我用的是凤凰版1.5.3

然后我生成了一个“组织”模块mix phx.gen.live Orgs Org orgs name:string email_end:string avatar_url:string description:string

      scope "/orgs", TopicalWeb.OrgLive do
        live "/", Index, :index
        live "/new", Index, :new
        live "/:id/edit", Index, :edit

        live "/:id", Show, :show
        live "/:id/show/edit", Show, :edit
      end

我发现我的 phoenix_live_view 版本太旧了：

-      {:phoenix_live_view, "~> 0.12.0"},
+      {:phoenix_live_view, "~> 0.13"},

注意：您可能想运行mix hex.search phoenix_live_view以找出最新版本：
