jupyter笔记本的R内核在安装时死机

Question

我刚刚在Windows 10上为jupyter笔记本安装了R内核,并且在这篇文章中得到了与OP相同的错误.下面粘贴的是单击"内核错误"按钮时显示的错误.

Traceback (most recent call last):
  File "C:\Python27\lib\site-packages\notebook\base\handlers.py", line 436, in wrapper
    result = yield gen.maybe_future(method(self, *args, **kwargs))

    model = sm.create_session(path=path, kernel_name=kernel_name)

    startupinfo)
WindowsError: [Error 2] The system cannot find the file specified

我尝试了很多东西,但我不确定自己是否会让情况变得更糟.

- 我已添加C:\Program Files\R\R-3.2.2\bin到我的系统路径,因此可以在命令行上运行R. 我还尝试了添加C:\Program Files\R\R-3.2.2\bin和C:\Program Files\R\R-3.2.2\bin\x64我的系统路径以及用户路径的所有组合.在新笔记本下拉菜单下的笔记本用户界面中,我实际上现在看到两个R选项,我似乎无法摆脱它.

-I've试图同时运行> IRkernel::installspec(),并> IRkernel::installspec(user = FALSE)在RStudio.我从那以后删除了.json内核文件,%APPDATA%\jupyter\kernels因为我试图删除我在笔记本中看到的R复制.

- 我尝试在内容中添加kernel.json文件C:\Users\[username]\.ipython\kernels\R_kernel

{"argv": ["C:/Program Files/R/R-3.2.0/bin/R.exe","-e","IRkernel::main()",
"--args","{connection_file}"],
"display_name":"R"
}

这些都没有奏效.任何帮助表示赞赏.Python 2在我的笔记本上运行良好.
