No supported color terminal library Python/Jupyter

问题:

I'm trying to start a Jupyter Notebook server on my Windows 7 machine, but I keep getting this odd, seemingly unsearchable error after typing:

jupyter notebook 

into cmd.exe

C:\Users\zfleeman>jupyter notebook Traceback (most recent call last):   File "c:\python27\lib\runpy.py", line 174, in _run_module_as_main     "__main__", fname, loader, pkg_name)   File "c:\python27\lib\runpy.py", line 72, in _run_code     exec code in run_globals   File "C:\Python27\Scripts\jupyter-notebook.EXE\__main__.py", line 9, in <modul e>   File "c:\python27\lib\site-packages\jupyter_core\application.py", line 267, in  launch_instance     return super(JupyterApp, cls).launch_instance(argv=argv, **kwargs)   File "c:\python27\lib\site-packages\traitlets\config\application.py", line 657 , in launch_instance     app.initialize(argv)   File "<decorator-gen-7>", line 2, in initialize   File "c:\python27\lib\site-packages\traitlets\config\application.py", line 87,  in catch_config_error     return method(app, *args, **kwargs)   File "c:\python27\lib\site-packages\notebook\notebookapp.py", line 1290, in in itialize     super(NotebookApp, self).initialize(argv)   File "<decorator-gen-6>", line 2, in initialize   File "c:\python27\lib\site-packages\traitlets\config\application.py", line 87,  in catch_config_error     return method(app, *args, **kwargs)   File "c:\python27\lib\site-packages\jupyter_core\application.py", line 239, in  initialize     self.parse_command_line(argv)   File "c:\python27\lib\site-packages\notebook\notebookapp.py", line 1007, in pa rse_command_line     super(NotebookApp, self).parse_command_line(argv)   File "<decorator-gen-4>", line 2, in parse_command_line   File "c:\python27\lib\site-packages\traitlets\config\application.py", line 87,  in catch_config_error     return method(app, *args, **kwargs)   File "c:\python27\lib\site-packages\traitlets\config\application.py", line 536 , in parse_command_line     flags=flags, log=self.log)   File "c:\python27\lib\site-packages\traitlets\traitlets.py", line 556, in __ge t__     return self.get(obj, cls)   File "c:\python27\lib\site-packages\traitlets\traitlets.py", line 535, in get     value = self._validate(obj, dynamic_default())   File "c:\python27\lib\site-packages\traitlets\config\application.py", line 226 , in _log_default     _log_formatter = self._log_formatter_cls(fmt=self.log_format, datefmt=self.l og_datefmt)   File "c:\python27\lib\site-packages\tornado\log.py", line 154, in __init__     raise RuntimeError("No supported color terminal library") RuntimeError: No supported color terminal library 

This looks like more of a Windows problem than a Python problem. Can somebody give me some advice? I just need to launch my Notebook server.

回答1:

I just had the same problem!. As Ben said, apparently is an error of Tornado 4.5

I solved installing the previous package, Tornado 4.4.3

pip install tornado==4.4.3 

And then I just run the Jupyter Notebook in cmd.exe:

jupyter notebook 

回答2:

Do you have colorama installed? This looks like an error in the just-released Tornado 4.5 if you have colorama installed but do not call colorama.init().

回答3:

Disable color: In file c:\python27\lib\site-packages\tornado\log.py on line 112 look for color=True and change it to color=False. Or install curses module for Windows from this repository

回答4:

Had the same jupyter problem for Python 2.7 on windows 10 upon updating the Anaconda Python distribution. setting color=False for Tornado log file helped solve the problem.
