sciruby - 创建 iruby notebook 时内核死机

Question

我完全是 SciRuby 的菜鸟。我第一次使用 SciRuby。我正在关注这个 video 了解如何使用 SciRuby 并绘制图形、图表等。当我转到 localhost:8888 并从右侧下拉菜单创建新笔记本时 (Ruby 2.2.3)

我在家(~)目录

然后一开始它说 Kernel connecting，然后 dead kernel 消息一次又一次地弹出(在几秒钟的间隔内)。什么都没有发生，我正在写的命令似乎没有效果。请解决这个问题，非常感谢。

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

Answer 1

Ivan 的回答给了我提示。

除了声明 iruby 和 nyaplot gem 之外，您还需要声明适当的 ZeroMQ 接口(interface)。

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 处理项目，则需要在规范中包含以下两行:

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

如果您使用的是 nyaplot，还有一个。
