Jupyter Notebook 500：内部服务器错误

问题描述 投票：9回答：8

我想学习如何使用Jupyter Notebook。到目前为止，我已经设法下载并安装它（使用pip），但是我无法打开它。

我打开它打开它：

jupyter notebook

在我的终端。它在我的浏览器中打开，其中包含以下URL：

http://localhost:8888/tree

我得到一个大的：

500 : Internal Server Error

信息。有人能指出我出错的方向吗？

我的终端中的完整错误消息：

尝试按建议更新ipython时，会生成以下错误消息：

有类似的问题。使用此命令升级ipython后修复了它

sudo pip install --upgrade "ipython[all]"

注意：确保使用双引号和[all]键入ipython

我也遇到过这个问题。我的根本原因是我已经安装了具有root权限的Jinja2（在我知道之前使用过sudo pip install）。

我的解决方案是使用sudo pip uninstall卸载Jinja2（这是必需的，因为它是以root权限安装的），并重新运行pip install jupyter以使用常规用户权限重新安装它。

$ sudo pip uninstall Jinja2
$ pip install jupyter

虽然使用sudo在这里安装工程，但从长远来看会使问题变得更糟，因为它的所有软件包都安装了root权限，导致将来与其他软件包一起出现这样的问题。这有点像踢，可以在路上。

只要它有效，许多人当然不会在意。但对于那些我认为我会提到的人。

没有办法确定违规包是什么，但它可能是堆栈跟踪中的一个。我注意到Jinja2是我早期在Python中隐约记得的那个，所以我从那里开始工作。

尝试先升级jupyter hub

pip install --upgrade jupyterhub


pip install --upgrade --user nbconvert

在Windows 10上也为我工作。

我有同样的问题，我的解决方案是将Jinja2包更新为版本Jinja2-2.8。

要更新它，我使用easy_install命令如下：

sudo easy_install -U python-jinja2[all]

之后，修复了500：内部服务器错误。

我在2009年3月22日有这个问题，对我有用的是更新conda然后使用pip升级jupyter：

conda update --all
pip install jupyter --upgrade

我有同样的问题，有点痛苦，直到我设法解决它。为我工作的神奇线条是

conda install -c conda-forge jupyter_contrib_nbextensions
