没有支持的彩色终端库Python/Jupyter

Question

我正在尝试在我的Windows 7机器上启动一个Jupyter Notebook服务器,但在输入后我仍然收到这个奇怪的,看似无法检测到的错误:

jupyter notebook

进入cmd.exe

C:\Users\zfleeman>jupyter notebook

这看起来像是一个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

我只是遇到了同样的问题!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

然后我只需运行Jupyter笔记本cmd.exe:

jupyter notebook
