"Using MLAPI" 给出错误消息,即使我安装了 MLAPI

"Using MLAPI" gives error message, even when I have MLAPI installed

我有 MLAPI (https://docs-multiplayer.unity3d.com/docs/migration/install/index.html) installed with Tanks multiplayer (https://assetstore.unity.com/packages/templates/tutorials/tanks-multiplayer-mlapi-photon-mirror-69172#description),当我为 MLAPI 导入坦克多人游戏代码时,出现错误:"error CS0246 : 找不到类型或命名空间名称 'MLAPI'(是否缺少 using 指令或程序集引用?)“,即使已安装,我也不知道该怎么做
