I have problem with LiveView.ex

Hello good friends I got some problem to compile and run my localhost with problem

== Compilation error in file lib/counter_web/live/counter_live.ex ==
** (CompileError) lib/counter_web/live/counter_live.ex:2: module Phoenix.LiveView is not loaded and could not be found
(elixir) expanding macro: Kernel.use/1

I wish someone can help me :slight_smile:

Have you fetched the dependencies with mix deps.get?

Inside my live folder, I create a file counter_live.ex

defmodule CounterWeb.CounterLive do
  use Phoenix.LiveView

  def mount(_session, socket) do
    socket = assign(socket, :count, 0)
    {:ok, socket}

  def render(assigns) do
    <h1> Count: <%= @count %> </h1>
    <label>Counter: 0</label>
    <button> + </button>
    <button> - </button>

yes All dependencies are up to date…

So which version of liveview are you using exactly, please tell us the version as specified in mix.exs and as resolved in mix.lock.
