无法启动JupyterNotebook
我无法在 Anaconda 上启动 Jupyter。我正在使用windows，我怎样才能摆脱这个错误？错误说：
Traceback (most recent call last):
File "C:UsersUseranaconda3Scriptsjupyter-notebook-script.py", line 6, in
from notebook.notebookapp import main
File "C:UsersUseranaconda3libsite-packagesnotebooknotebookapp.py", line 64, in
raise ImportError(_("The Jupyter Notebook requires tornado >= 5.0, but you have %s") % tornado.version)
ImportError: The Jupyter Notebook requires tornado >= 5.0, but you have 4.5.3
回答
您可能可以将其从系统中删除，然后使用 for python 将其重新打开
sudo apt-get remove python-tornado
sudo pip install tornado
同样，如果需要，您可以为 python 3 运行它
sudo apt-get remove python3-tornado
sudo pip3 install -U tornado
或者您可以尝试以下方法升级龙卷风
sudo pip install tornado --upgrade
