在Windows中的iPython筆記本 - 在啓動時出錯

Question

我想拼命地讓ipython筆記本在Windows環境中工作。我安裝了Continuum IO的Anaconda，這是Python的科學發行版。我想使用ipython筆記本，但出現以下錯誤。 ipython在終端工作正常。有什麼想法嗎？

更新：如以下要求，這裏是我的系統上sys.path的輸出。

['', 
'C:\\Anaconda\\scripts', 
'C:\\Anaconda\\lib\\site-packages\\distribute-0.6.45-py2.7.egg', 
'C:\\Anaconda', 
'C:\\Users\\btibert\\ C:\\Anaconda\\Scripts',

'C:\\Anaconda\\lib\\site-packages\\Pythonwin', 
'C:\\Users\\btibert\\AppData\\Roaming\\Python\\Python27\\site-packages\\IPython\\extensions'] 

這裏是錯誤：

Answer 1

我想出了一種方法來解決這個問題。我真的不認爲我必須得到這個級別，但我完全卸載了我能找到的每一個可能的python實例。我

1. unisntalled蟒蛇CE
2. 去除PATH
3. 每參考蟒蛇編輯我的註冊表清理出Python數據（但沒有留下Python的文件夾）從列出的應用程序/漫遊路徑
4. 刪除蟒蛇以上由@IanSR

基本上，我刪除了每一個可能的引用到python我可以找到然後重新安裝Anaconda CE。瞧瞧，蟒蛇安裝（看來）已經按照分銷商的預期工作。

這將有助於瞭解你的sys.path是什麼。你可以這樣做：

$ ipython 

In [1]: import sys 

In [2]: sys.path 

然後在這裏分享輸出。其次，要檢查哪些文件在此目錄中有：

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

理想情況下，你會看到auto.py那裏，如果C:\Users\btibert\AppData\Roaming\Python\Python27\site-packages是在sys.path中那麼爲什麼它不工作是個謎，但如果該文件不存在，該目錄不存在，或者site-packages的路徑不在sys.path中，那麼需要首先解決這些問題。

讓我們知道，我們可以嘗試從那裏拿走！
