I'm pretty new to the forum, so I'm sorry if this question has already been answered. I looked around, and although I saw that some had similar issues, I couldn't find the solution to my problem on any previous posts. So - here goes...

我正在运行Mac OS X 10.11.5，Jupyter笔记本电脑版本4.2.1，R版本3.2.2

I'm running Mac OS X 10.11.5, Jupyter notebook version 4.2.1, R version 3.2.2

我使用以下命令为Jupyter Notebook安装了R内核-

I installed the R kernel for Jupyter notebook with the following command -

conda install -c r r-irkernel

现在，当我启动Jupyter笔记本电脑时，我看到"R"作为笔记本"下方右侧下拉菜单中的选项之一出现.但是，当我尝试创建R笔记本时，内核崩溃，并且在终端中出现以下错误:

Now, when I launch Jupyter notebook, I see 'R' appears as one of the options in the drop down menu on the right hand side under 'notebooks.' However, when I try to create an R notebook, the kernel crashes and I get the following error in terminal:

有什么想法我可以从这里去吗?

Any idea where I can go from here?

谢谢！
