Question

我在SciRuby中完全是菜鸟。我第一次使用SciRuby。我正在关注这个video 以概述如何使用SciRuby并绘制图表，图表等。当我转到localhost：8888并从右下拉创建新的笔记本（Ruby 2.2.3）

我在家（〜）dir

notebook

然后首先它说内核连接然后死内核消息一次又一次地弹出（在几秒的间隙内）。什么都没发生，我写的命令似乎没有任何效果。非常感谢这个问题解决了。

You should install rbczmq or ffi_rzmq before running iruby notebook. See README.

Answer 1

Ivan的回答让我感到惊讶。

除了声明iruby和nyaplot gems之外，还需要声明相应的ZeroMQ接口。

所以，在你的Gemfile中，

gem 'iruby'
gem 'nyaplot'
gem 'rbczmq' # or 'ffi-rzmq'
# any other gems you want to use should go here too

或者，如果您正在使用gemspec进行项目，则规范中需要以下两行：

gem.add_development_dependency 'iruby', '~>0.2'
gem.add_development_dependency 'rbczmq'

还有一个用于nyaplot，如果你正在使用它。

Answer 2

尝试将名为Gemfile的文件添加到您用来运行iruby的文件夹中，其中包含以下内容：

gem 'iruby'
gem 'nyaplot'
# any other gems you want to use should go here too

Answer 3

这种方法帮助了我：
我在SciRuby's GitHub页面后面的jupyter笔记本中安装了ruby内核，当天运行良好。但过了几天，我再次运行它，内核开始死了。
我不知道背后的确切原因，但我再次按照相同的方法，它安装了一些额外的宝石，它工作了!!
按照这一点

sudo apt install libtool libffi-dev ruby ruby-dev make
sudo apt install libzmq3-dev libczmq-dev
gem install cztop iruby
iruby register --force

再次运行笔记本

jupyter-notebook

内核在创建iruby笔记本时死亡
