Elixir & Phoenix：将 memcache_client 库添加到应用

Question

我想在我的 Phoenix 应用程序中使用这个库来连接到 Memcache：https://github.com/tsharju/memcache_client

当我运行我的服务器出现此错误时：

** (exit) exited in: :gen_server.call(Memcache.Client.Pool, {:checkout, #Reference<0.0.1.768>, true}, 5000)
    ** (EXIT) no process: the process is not alive or there's no process currently associated with the given name, possibly because its application isn't started
              :erlang.send(Memcache.Client.Pool, {:"$gen_cast", {:cancel_waiting, #Reference<0.0.1.768>}}, [:noconnect])

我知道有一个文档说：

Also, remember to add :memcache_client to your :applications list if you wish that the application is started automatically.

但我不明白我应该在我的 Phoenix 应用程序中做什么。有什么帮助吗？谢谢！

Answer 1

在mix.exs中，将:memcache_client添加到函数application/0中的键:applications:

def application do
  [mod: {MyApp, []},
   applications: [:phoenix, :phoenix_pubsub, :phoenix_html, :cowboy, :logger, :gettext,
                  :phoenix_ecto, :postgrex]]
end

->

def application do
  [mod: {MyApp, []},
   applications: [:phoenix, :phoenix_pubsub, :phoenix_html, :cowboy, :logger, :gettext,
                  :phoenix_ecto, :postgrex, :memcache_client]]
end

Answer 2

解决了。只需编辑 mix.exs 文件。 returns 应用列表中有一个方法应用：

def application do
[mod: {MyApp, []},
 applications: [:phoenix, :phoenix_pubsub, :phoenix_html, :cowboy, :logger, :gettext,
                :phoenix_ecto, :postgrex, :memcache_client]] # add memcache_client here

结束
