Question

我正在尝试在Ubuntu 14.04上安装和运行Jupyter。安装似乎没问题，但是当我打开浏览器并尝试打开Python笔记本时，浏览器会弹出一个窗口，其中包含连接失败标题：

无法建立与笔记本电脑服务器的连接。笔记本电脑将继续尝试重新连接。检查网络连接或笔记本服务器配置。

问题出在服务器端：Jupyter无法找到 nbextensions 资源，如下面的警告线所示：

404 GET /nbextensions/widgets/notebook/js/extension.js

之前已经提出此错误，但没有建议的解决方案为我解决。我在Ubuntu 16.04上遇到了同样的问题。

这是我的配置：

~$ python -V
Python 3.5.3
~$ pip3 -V
pip 9.0.1 from /opt/python3.5/lib/python3.5/site-packages (python 3.5)
~$ jupyter --version
4.2.1
~$ jupyter notebook --version
4.3.2

这是服务器上的Jupyter输出：

~$ jupyter notebook --ip=192.168.2.15 --port=8080 --no-browser

Answer 1

需要加载nbextensions

安装pip3 install ipywidgets

更改档案：~/.jupyter/nbconfig/notebook.json

{
  "load_extensions": {
    "jupyter-js-widgets/extension": true
  }
}

其他套餐：

pip3 install jupyter-js-widgets-nbextension
pip3 install nbextensions

重新运行jupyter Notebook
