在Windows上使用IPython笔记本500服务器错误

Question

我刚刚在Windows 7 Professional 64位上安装了全新的IPython笔记本.

我采取的步骤是:

1. 从http://python.org安装Python 3.4.1
2. > pip install ipython[notebook]
3. > pip install pywin numpy pygments nodeenv

我可以打开笔记本了.

但是,当我选择File > Print Preview或File > Download as HTML我得到500服务器错误.

堆栈跟踪是:

安装node.js和Pandocs没有帮助.

有关如何修复此错误的任何想法？

我把它作为 IPython团队的一个问题提出来了.

Answer 1

这有效:

1. 右键单击Command Prompt"开始"菜单中的.
2. 选择Run as administrator.
3. 选择Yes在用户帐户控制对话框.
4. 运行ipython notebook中所产生的命令提示符窗口.

基本上,它必须由于某种原因以管理员身份运行.
