不能全新安裝

Question

我做了後運行`jupyter notebook`：

pip install --upgrade pip 
pip install jupyter 
jupyter notebook 

而且我得到以下錯誤：

Traceback (most recent call last): 
    File "/usr/local/bin/jupyter-notebook", line 7, in <module> 
    from notebook.notebookapp import main 
    File "/Library/Python/2.7/site-packages/notebook/notebookapp.py", line 61, in <module> 
    from .services.kernels.kernelmanager import MappingKernelManager

    File "/Library/Python/2.7/site-packages/dateutil/tz/_common.py", line 2, in <module> 
    from six.moves import _thread 
ImportError: cannot import name _thread 

感謝。

似乎一些Matplotlib用戶有類似的問題（請參閱there），並通過重新安裝dateutil解決它。

sudo pip uninstall python-dateutil 
sudo pip install python-dateutil==2.2 

您可能想要使用較新的版本（最新版本爲2.6）嘗試。
