我試圖運行matlabs appdesigner，但我得到這個錯誤：無法啓動appdesigner

我使用Arch Linux的，我安裝了Matlab的2016B，我還安裝了庫列在AUR matlab軟件包中，沒有成功。我還安裝了ncurses5軟件包並安裝了oracle-jdk8。我該如何解決這個錯誤？
你正在運行的代碼是什麼？只是'appdesigner'？還是你想加載一些現有的AppDesigner應用程序？這個錯誤可能意味着'uifigure'句柄被存儲爲'double'（這在以前的MATLAB版本中通常會遇到），看看'isvalid'是一種圖形對象的方法......默認情況下，MATLAB R2016b（at至少在Windows上）使用'Java 1.7.0_60-b19'（參見'version -java'）。 –
這是由於在matlab提示符處輸入appdesigner而造成的 – tofiffe
嘗試在'appdesigner'之前運行'dbstop if error'，那麼當它中斷時，'obj.WebWindow'的內容是什麼？它在函數中說，當「_MATLABWindow進程可以意外終止時，執行此代碼，就像從任務管理器或Linux kill command_」一樣。難道系統上的某些東西在它準備好之前就會殺死web窗口？ –
