python - 加载 Jupyter Notebook 扩展时出错

Question

我正在使用带有 OS Sierra 的 Macbook，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 上看到了一些相关问题，但它们似乎与安装特定扩展有关。

此外，其中一个解决方案似乎建议pip install jupyter_nbextensions_configurator，但从下面的输出可以看出，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: No module named 'jupyter_nbextensions_configurator' 是错误消息之一。

我在这里错过了什么？谢谢!

我遇到了同样的问题。这是我解决它的方法。

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，我会得到这个错误:

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

所以我猜问题是因为您的系统上有多个版本的 Python。 Anaconda 使用的和“普通 pip”使用的可能不同。
