Question

我试图在我的Windows 7计算机上启动一个Jupyter Notebook服务器，但在输入后我仍然收到这个奇怪的，看似无法检测的错误：

jupyter notebook

进入cmd.exe

C:\Users\zfleeman>jupyter notebook

这看起来更像是Windows问题，而不是Python问题。有人可以给我一些建议吗？我只需要启动我的笔记本电脑服务器。

Answer 1

我刚遇到同样的问题！正如Ben所说，显然是Tornado 4.5的错误

我解决了安装以前的软件包Tornado 4.4.3

的问题

pip install tornado==4.4.3

然后我在cmd.exe中运行Jupyter Notebook：

jupyter notebook

Answer 2

您是否安装了colorama？如果您已安装colorama但未调用colorama.init()，则在刚刚发布的Tornado 4.5中看起来像是一个错误。

Answer 3

禁用颜色：在第112行的文件c:\python27\lib\site-packages\tornado\log.py中查找color=True并将其更改为color=False。或者从this repository

安装适用于Windows的curses模块

Answer 4

在更新Anaconda Python发行版时，Windows 10上的Python 2.7存在同样的jupyter问题。为Tornado日志文件设置color = False有助于解决问题。

没有支持的彩色终端库Python / Jupyter
