Firebase 4.3.0播放服务解析器错误

Question

我刚刚在Unity中安装了NullReferenceException: Object reference not set to an instance of an object GooglePlayServices.ResolverVer1_1.GenerateGradleProperties (System.Collections.Generic.Dictionary`2 properties) GooglePlayServices.ResolverVer1_1.GradleResolution (System.String destinationDirectory, System.String androidSdkPath, Boolean logErrorOnMissingArtifacts, System.Action`1 resolutionComplete) GooglePlayServices.ResolverVer1_1.DoResolutionUnsafe (Google.JarResolver.PlayServicesSupport svcSupport, System.String destinationDirectory, System.Action resolutionComplete) GooglePlayServices.ResolverVer1_1+<DoResolution>c__AnonStorey3.<>m__0 () GooglePlayServices.ResolverVer1_1.UpdateTryResolution () UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at C:/buildslave/unity/build/Editor/Mono/EditorApplication.cs:127) 一个新项目。首先我更新了版本处理程序并获得了成功消息，然后我选择了＆＃34; Play服务解析器 - ＆gt; Android解析器 - ＆gt;解决＆＃34; ，我收到了以下错误：

//my-filter.filter.js

function myFilter($filter){
    return filter(input){
        return $filter('currency')(input, 'X');;
    }
}

myFilter.$inject = ['$filter'];

export default myFilter;
