Jupyter笔记本500：内部服务器错误

Question

我想了解如何使用Jupyter Notebook。到目前为止，我已经设法下载并安装它（使用pip），但我无法打开它。在我的终端

jupyter notebook 

：

我通过键入打开它。它在我的浏览器中打开，用网址：

http://localhost:8888/tree 

，我只是得到一个大：

500 : Internal Server Error 

消息。有人能指出我发生什么问题的正确方向吗？

在我的终端完整的错误消息：

当试图更新IPython的作为建议，制备以下错误消息：

Answer 1

当时有类似的问题。升级IPython中使用此命令

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

注后修正它：确保用双引号键入IPython的和[all]

Answer 2

我也遇到了这个问题。在我的情况下，根本原因是我已经有Jinja2安装了根权限（在我知道更好之前使用了sudo pip install）。

我的解决方案是卸载Jinja2与sudo pip uninstall（这是必需的，因为它安装了根权限），并重新运行pip install jupyter重新安装它与常规用户权限。

$ sudo pip uninstall Jinja2 
$ pip install jupyter 

在使用sudo在这里安装工程，它使从长远来看问题更严重，因为它的所有包都用root权限安装，导致这样在未来与其他产品进行进一步的问题。这有点像踢，可以在路上。

许多人不会在乎，只要它有效。但对于那些我认为我会提及的人。

无法确切知道有问题的软件包是什么，但它可能是堆栈跟踪中的一个。我注意到Jinja2是我在Python初期隐约记得的，所以我从那里开始并且工作。

Answer 3

我有同样的问题，我的解决方案是更新Jinja2包到版本Jinja2-2.8。

要更新它，我用的easy_install命令如下：

sudo easy_install -U python-jinja2[all] 

在此之后，500：内部服务器错误是固定的。
