我尝试构建一个针对SP16 FP2和SP Online的新Webpart .
https://docs.microsoft.com/en-us/sharepoint/dev/spfx/web-parts/get-started/build-a-hello-world-web-part
当我将程序包部署到我的SP16时，应用程序不会显示在我的其他站点上 .
在我的ULS日志中，我只有以下错误：
Unexpected Exception in SPDistributedCachePointerWrapper::InitializeDataCacheFactory for usage 'DistributedClientSideAppUpdateTimeCache' - Exception 'System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary. at System.Collections.Concurrent.ConcurrentDictionary`2.get_Item(TKey key) at Microsoft.SharePoint.DistributedCaching.SPDistributedCachePointerWrapper.InitializeDataCacheFactory()'.
我有什么想法我做错了吗？
