我最近按照这里的说明安装了ipython:http://ardiyu07.blogspot.com/2012/04/ipython-012-installation-in-cygwin.html。
当我运行'ipython --pylab'
时,出现以下错误消息。我搜索了一下,发现了关于这个错误的帖子,但是在不同的上下文中。当我使用--pylab参数启动ipython时会发生这种情况。我知道这与matplotlib gui交互有关,但不确定究竟是什么。我很欣赏这个指导。
$ ipython --pylab

setuptools的我不知道,如果是Tkinter的使用Cygwin兼容。你需要使用cygwin吗?你可以在Windows上安装IPython&matplotlib而不需要cygwin。 – 2013-03-24 18:56:35
感谢您的反馈。我对cygwin有其他依赖关系,这就是为什么我想保持与运行时环境一致的原因。带有上面引用的安装说明的网站似乎表明,ipython和matplotlib应该可以与cygwin一起工作,因为这些说明适用于cygwin。 – codingknob 2013-03-24 20:05:30
看来您现在需要在Cygwin中为tkinter安装X11 - 链接的帖子可能使用的是旧版本。 http://cygwin.com/ml/cygwin/2012-02/msg00115.html – 2013-03-24 20:54:39
