Jupyter Matlab的核心JSON错误

我真的不知道我的问题的根源是什么（是否Jupyter笔记本，MATLAB，matlab_kernel或pymatbridge），所以我想我只是张贴的问题在这里与所有的标签。Jupyter Matlab的核心JSON错误

我从远程服务器（Ubuntu的14.04）运行MATLAB内核Jupyter笔记本。为了设置MATLAB内核，我按照these的说明安装了pymatbridge和matlab_kernel。好像本身运行就好了（测试了几个简单的MATLAB命令输出和错误消息打印为预期）MATLAB的内核，当我在Jupyter笔记本调用它不是MATLAB本身工作正常，但是当我尝试运行另一通过

addpath('/path/to/function') 
y = function(x)

我收到以下错误MATLAB功能的笔记本：

任何想法可能会导致这个错误，而究竟是什么错误的手段？

也许它返回None，因为在你的命令是错误的？ add path与addpath？

addpath('/path/to/function')

哦拍，'添加路径'在我原来的问题只是一个错字;它已被更新。我想要说的是，我可以在任何通过MATLAB的接口或通过终端MATLAB MATLAB命令行直接做同样的呼叫，并且两个路径添加和函数调用做工精细。只有通过Jupyter笔记本内核才会引发错误。 – itf
