在Windows中的iPython笔记本 - 在启动时出错

Question

我想拼命地让ipython笔记本在Windows环境中工作。我安装了Continuum IO的Anaconda，这是Python的科学发行版。我想使用ipython笔记本，但出现以下错误。 ipython在终端工作正常。有什么想法吗？

更新：如以下要求，这里是我的系统上sys.path的输出。

['',

这里是错误：

Answer 1

我想出了一种方法来解决这个问题。我真的不认为我必须得到这个级别，但我完全卸载了我能找到的每一个可能的python实例。我

1. unisntalled蟒蛇CE
2. 去除PATH
3. 每参考蟒蛇编辑我的注册表清理出Python数据（但没有留下Python的文件夹）从列出的应用程序/漫游路径
4. 删除蟒蛇以上由@IanSR

基本上，我删除了每一个可能的引用到python我可以找到然后重新安装Anaconda CE。瞧瞧，蟒蛇安装（看来）已经按照分销商的预期工作。

这将有助于了解你的sys.path是什么。你可以这样做：

$ ipython 

In [1]: import sys 

In [2]: sys.path 

然后在这里分享输出。其次，要检查哪些文件在此目录中有：

C:\Users\btibert\AppData\Roaming\Python\Python27\site-packages\zmq\eventloop\platform 

理想情况下，你会看到auto.py那里，如果C:\Users\btibert\AppData\Roaming\Python\Python27\site-packages是在sys.path中那么为什么它不工作是个谜，但如果该文件不存在，该目录不存在，或者site-packages的路径不在sys.path中，那么需要首先解决这些问题。

让我们知道，我们可以尝试从那里拿走！
