尝试为Jupyter笔记本安装irkernel,我面临以下问题:

IRkernel::installspec()
# Results in
# Error in IRkernel::installspec() : 
# jupyter-client has to be installed but âjupyter kernelspec --versionâ exited with code 1.

这与一个事实有关:在Windows上,需要一个破折号。事实上,这是行不通的:

> jupyter kernelspec --version
Error executing Jupyter command 'kernelspec': [Errno 'jupyter-kernelspec' not found] 2

在这种情况下:

> jupyter-kernelspec --version
5.2.2

有办法解决这个问题吗?

我发布了 Error executing Jupyter command 'kernelspec' 此处发布: Jupyter commands work only with a dash (e.g. jupyter-kernelspec instead of jupyter kernelspec)

为了安装R内核,我使用的解决方法是调整 installspec function's code 并在本地执行这个经过调整的版本。

修改内容是替换:

17: exit_code <- system2('jupyter', c('kernelspec', '--version'), FALSE, FALSE)
42: args <- c('kernelspec', 'install', '--replace', '--name', name, user_flag, prefix_flag, file.path(tmp_name, 'kernelspec'))
43: exit_code <- system2('jupyter', args)

通过:

17: exit_code <- system2('jupyter-kernelspec', '--version', FALSE, FALSE)
42: args <- c('install', '--replace', '--name', name, user_flag, prefix_flag, file.path(tmp_name, 'kernelspec'))
43: exit_code <- system2('jupyter-kernelspec', args)

编辑更好、更简单的解决方案: Jupyter commands work only with a dash (e.g. jupyter-kernelspec instead of jupyter kernelspec)
