Question

我刚刚在Windows 10上为jupyter笔记本安装了R内核，并且在post中遇到与OP相同的错误。下面粘贴的是当我点击＆＃34; Kernel error＆＃34;按钮。

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))
  File "C:\Python27\lib\site-packages\notebook\services\sessions\handlers.py", line 56, in post
    model = sm.create_session(path=path, kernel_name=kernel_name)

    kernel_name=kernel_name)

  File "C:\Python27\lib\subprocess.py", line 882, in _execute_child
    startupinfo)
WindowsError: [Error 2] The system cannot find the file specified

我尝试了很多事情，而且我不确定我是否会让事情变得更糟。

- 我已将C:\Program Files\R\R-3.2.2\bin添加到我的系统路径中，因此可以在命令行上运行R.我还尝试了将C:\Program Files\R\R-3.2.2\bin和C:\Program Files\R\R-3.2.2\bin\x64添加到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。

- 我尝试在RStudio中同时运行> IRkernel::installspec()和> IRkernel::installspec(user = FALSE)。我从那以后删除了%APPDATA%\jupyter\kernels中的.json内核文件，因为我试图删除我在笔记本中看到的R复制。

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

{"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。
