安装 RKernel [英] Installing RKernel

问题描述

尽管我付出了很多努力，但我还是无法在 Canopy 上为我的 IPython/Jupyter 笔记本安装 R 内核.

Despite all my efforts, I wasn't able to install the R kernel for my IPython/Jupyter notebook on Canopy.

我已严格遵守以下明确说明:http://www.michaelpacer.com/maths/r-kernel-for-ipython-笔记本(或者，http://irkernel.github.io/installation/)

I've closely followed the clear instructions given in: http://www.michaelpacer.com/maths/r-kernel-for-ipython-notebook (or, alternatively, http://irkernel.github.io/installation/)

一切顺利，直到在 Jupyter 上安装内核的最后一步:

All goes well until the last step that install the kernel on Jupyter:

IRkernel::installspec()

这是我收到的奇怪信息:

Here is the weird message I get:

File "/Users/julien/Library/Enthought/Canopy_64bit/User/bin/jupyter-kernelspec", line 8
from jupyter_client.kernelspecapp import KernelSpecApp.launch_instance
                                                      ^
SyntaxError: invalid syntax

我的配置如下:

• 配备 El Capitan 的 Macbook
• R 版本 3.2.2
• IPython 4.0.1
• Jupyter 4.0.6

推荐答案

事实证明文件jupyter-kernelspec"由于某种原因已损坏.我用下面的代码替换了它:

It turns out that the file "jupyter-kernelspec " was corrupted for some reason. I replaced it by the following code:

#!/usr/bin/env python
from jupyter_client.kernelspecapp import KernelSpecApp
def main():
    KernelSpecApp.launch_instance()
if __name__ == '__main__':
    main()

它解决了我的问题.
