加载 Jupyter Notebook 扩展时出错 [英] Error loading Jupyter Notebook Extensions

问题描述

我使用 Macbook 和 OS Sierra，运行 Python 3.6.1 和 Jupyter Notebook Server 5.0.0我按照 https://github.com/ipython-contrib/jupyter_contrib_nbextensions 上提到的说明安装了 Jupyter Notebook 扩展

I am using a Macbook with OS Sierra, and running Python 3.6.1 and Jupyter Notebook Server 5.0.0 I installed Jupyter Notebook extensions, following the instructions as mentioned on https://github.com/ipython-contrib/jupyter_contrib_nbextensions

虽然笔记本在我的系统上运行良好，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，但它们似乎与安装特定扩展有关.

While the notebooks work fine on my system, I cannot view the nbextensions tab. The following is the error log I see on running jupyter notebook in terminal. I have seen some related problems posted here on SO, but they seem to be about installing specific extensions.

此外，其中一种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.

Further, one of the solutions seemed to be suggest pip install jupyter_nbextensions_configurator, but as can be seen from the output below, I already have the extension installed.

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: No module named 'jupyter_nbextensions_configurator' 是错误消息之一.

However, in the logs, you will notice that ModuleNotFoundError: No module named 'jupyter_nbextensions_configurator' is one of the error messages.

我在这里错过了什么?谢谢！

What am I missing here? Thanks!

推荐答案

我遇到了同样的问题.这是我解决它的方法.

I had the same problem. Here is how I solved it.

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

I have downloaded Anaconda python version 3.7. I already had Python 3.6.7 on my system.

如果我这样做，我会得到这个错误:

I'd get this error if I did:

pip install jupyter_contrib_nbextensions

为了解决它，我做到了:

To solve it, I did:

python3.7 -m pip install jupyter_contrib_nbextensions

我还没有尝试过，但这也可以解决您的问题:

I have not tried this, but this could solve your problem too:

conda install -c conda-forge jupyter_nbextensions_configurator

所以我猜这个问题是因为你的系统上有多个版本的 Python.Anaconda 使用的一种和正常点"使用的一种.用途可能不同.

So I guess the problem is because of there being multiple versions of Python on your system. The one which Anaconda uses and the one which the "normal pip" uses are probably different.
