错误： error CS0683: UniRx.ReactiveCollection<T>.IReactiveCollection<T>.get_Item(int)' explicit method implementation cannot implementUniRx.IReactiveCollection<T>.this[int].get' because it is an accessor

   int Test { get; }  
}

{  
	//原
   int IExample.get_Test() { return 0; } // CS0683  
   //修改后
   int IExample.Test { get{ return 0; } } // correct  
}

错误：CS433:类型“MonoBehaviour同时存在于UnityEngineCoreModuleVersion0.0.0.0.Cultureneutral PublicKeyTokennull和“UnityEngineVersion0.0.0.0,CultureneutralPublicKeyTokennull中

删掉UnityEngine.dll

UNITY某个新版本后，把UnityEngine.dll的东西全部拆解到其它DLL了，主要核心功能在UnityEngine.coreModule.dll中，其它功能比如UnityEngine.Coremodule等。 而UnityEngine.dll完全是一个空壳，打开看里面全是空类，空代码。

错误：Unity打包WebGL在网页运行出现“To use diopen,you need yo use Emscript's linking support”问题解决方法。

解决方案

**错误：** $LOAD_DATA_FROM_SUBPACKAGE is not defined

1.检查打包的路径是否有中文，如果有中文，则可能会导致minigame/wasmcode/.webgl.wasm.code.unityweb.wasm.br代码分包文件无法生成

2.在转换小游戏时，要确保代码分包和资源首包的加起来的文件大小不能超过20M

错误：An error occurred while resolving packages: Project has invalid dependencies: com.unity.package-manager-ui: Package [com.unity.package-manager-ui@2.1.2] cannot be found Package com.unity.textmeshpro@2.0.0 has invalid dependencies: com.unity.ugui: Package [com.unity.ugui@1.0.0] cannot be found

把工程目录下的Packages目录中的manifest.json删掉, 然后再自动生成

错误：error CS0433: The imported type System.Xml.XmlNode is defined multiple times

方法一：将Plugins文件夹中System.Xml.dll移除

方法二：File - Build Setting - Player Setting - Other Settings - Scripting Runtime Version - 改为.Net 4.x

错误：Errors during import of AudioClip Assets/Resources/sounds/effects/Battle_TroopB_Shoot3.wav: FSBTool ERROR: The format of the source file is invalid, see output for details. FSBTool ERROR: Internal error from FMOD sub-system.
 

• 方法一：检查音频文件的采样率：Unity可能无法处理某些特定的采样率。尝试将音频文件的采样率更改为44100Hz或48000Hz。

• 方法二：重新导入音频文件：右键 - ReImport
