我无法将第二个文件上传到我的共享点列表（附件）。但是第一个文件作为附件在列表中正确上传。我已经使用了所有的必要引用。代码在此行中断：
$.getScript(scriptbase + "SP.RequestExecutor.js", function ()
错误来自interner explorer而不是chrome。错误如下：Sys.InvalidOperationException: Type SP.PostMessageRequestInfo has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.
任何人都可以告诉我们是什么问题。
