无法在Jupyter笔记本中加载IRKernel

Question

我对论坛很新,所以如果这个问题已经得到解答,我很抱歉.我环顾四周,虽然我看到有些人有类似的问题,但在以前的任何帖子中我找不到解决问题的方法.所以 - 这里......

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

我使用以下命令为Jupyter笔记本安装了R内核 -

conda install -c r r-irkernel

现在,当我推出Jupyter笔记本时,我看到'R'显示为"笔记本电脑"右侧下拉菜单中的一个选项.但是,当我尝试创建一个R笔记本时,内核崩溃,我在终端中收到以下错误:

WARNING:root:kernel b42781ab-ebb1-45eb-8a54-d3801106fb94 restarted

知道我可以从哪里去吗？

谢谢!

在我的Mac上更新'R'后,我遇到了类似的问题.

以下步骤解决了我的问题

install.packages(c('pbdZMQ', 'repr', 'devtools'))  
devtools::install_github('IRkernel/IRdisplay')
devtools::install_github('IRkernel/IRkernel')
IRkernel::installspec()
