在加载Jupyter Notebook Extensions时出错

我正在使用OS Sierra与OS Sierra,并运行
Python 3.6.1和Jupyter Notebook Server 5.0.0

我按照
https://github.com/ipython-contrib/jupyter_contrib_nbextensions中提到的说明安装了Jupyter Notebook扩展

虽然笔记本电脑在我的系统上工作正常,但我无法查看nbextensions选项卡.以下是我在终端中运行jupyter notebook时看到的错误日志.我在SO上看到了一些相关的问题,但它们似乎是关于安装特定的扩展.

此外,其中一个解决方案似乎是建议pip install jupyter_nbextensions_configurator,但从下面的输出中可以看出,我已经安装了扩展.

Requirement already satisfied: traitlets in /usr/local/lib/python3.6/site-packages (from jupyter_nbextensions_configurator)
Requirement already satisfied: tornado in /usr/local/lib/python3.6/site-packages (from jupyter_nbextensions_configurator)

但是,在日志中,您会注意到ModuleNotFoundError:没有名为’jupyter_nbextensions_configurator’的模块是错误消息之一.

我在这里错过了什么?谢谢!

最佳答案 我有同样的问题.这是我如何解决它.

我已经下载了Anaconda python版本3.7.我的系统上已经安装了Python 3.6.7.

如果我这样做,我会收到此错误:

pip install jupyter_contrib_nbextensions

为了解决这个问题,我做了:

python3.7 -m pip install jupyter_contrib_nbextensions

我没试过这个,但这也可以解决你的问题:

conda install -c conda-forge jupyter_nbextensions_configurator

所以我想这个问题是因为你的系统上有多个版本的Python. Anaconda使用的那个和“普通pip”使用的那个可能是不同的.
