我正在按照 O'Reilly 视频教程 ( http://shop.oreilly.com/product/0636920044260.do ) 中的说明在 MacOS 10.10.5 上运行新的 Jupyter notebook 安装。安装 miniconda 后，我为 R 内核创建了一个环境：
conda create -n jupyter_r -c r r-irkernel r-recommended r-essentials anaconda rpy2 -y
在那个环境中，我可以启动 jupyter notebook 并创建一个新的 R notebook。
但是，当我尝试执行时：
library(dplyr)
我收到一个死内核错误，内核在我的终端中重新启动。
我可以成功执行：
library(ggplot2)
library(lattice)
library(reshape2)
似乎只有库（dplyr）会导致崩溃。我还验证了 anaconda 和 miniconda 安装都会发生这种情况。
崩溃的输出是：

关于造成这种情况的任何建议？我发现了许多对 jupyter 内核自发崩溃的引用，但似乎没有任何内容与 dplyr 相关。
谢谢，
