我刚刚在 64 位 Windows 7 Professional 上全新安装了 IPython 笔记本。
我采取的步骤如下:
- 从 python.org 安装 Python 3.4.1
pip 安装 ipython[notebook]
pip 安装 pywin numpy pygments nodeenv
我可以正常打开笔记本。但是,当我选择File > Print Preview
或时,File > Download as HTML
出现 500 服务器错误。
堆栈跟踪如下:

我以为那nodeenv
是 node.js
关于如何修复此错误您有什么想法吗?
答案1
这有效:
Command Prompt
在“开始”菜单中右键单击。- 选择
Run as administrator
。 Yes
在用户帐户控制对话框中选择。ipython notebook
在出现的命令提示符窗口中运行。
基本上,由于某种原因,它必须以管理员身份运行。
