Spyder將無法連接到內核/ iPython控制檯

由於昨晚我的筆記本電腦崩潰（原因不明），Spyder無法連接到內核。我得到這個錯誤：（JSON文件的名稱每次我試圖啓動一個IPython的控制檯時間變化）Spyder將無法連接到內核/ iPython控制檯

IOError: Could not find u'kernel-1809.json' in ['.', '~/Library/Jupyter/runtime']

這似乎並沒有被相關matplotlib 1.5的問題，即我在這裏看過其他地方 - 它使用1.4.3。

iPython（版本4.0.0）從命令行運行正常。

Mac 10.10.1（優勝美地）。 Spyder 2.3.7。 Python的64位2.7.10，QT 4.8.7 4.11.3達爾文

**進一步更新**

我刪除，PyQt4的（API第2版）我用戶目錄中.spyder2 /文件夾下的所有文件，重新打開Spyder，並且它能夠連接到iPython控制檯。到現在爲止還挺好。麻煩的是，當我添加一個路徑到PYTHONPATH管理器（所以我可以導入外部模塊，如nltk）時，我又回到了同樣的錯誤。

追加一些日誌到你的問題會很好。 – diegoperini

我有完全相同的問題。我試圖讓Spyder使用帶有nltk的virtualenv，並獲得相同的錯誤。刪除'.spyder2 /'並不是真正的解決方案，因爲它會重置所有Spyder設置，並且您又回到使用默認解釋器。你有沒有在這方面取得進展？ – silentser

@silentser - 我無法想象它。這個問題發生在我直接安裝的Spyder中。我最終在安裝過程中安裝了Anaconda並使用Spyder。現在不需要添加路徑到PYTHONPATH管理器，所以它工作正常。但是爲什麼另一個Spyder停止了這樣的工作，我仍然不知所措。祝你好運。 –

有類似的問題，並能夠通過創建一個新的virtualenv與安裝相同的依賴關係解決它。現在Spyder正在與PYTHONPATH合作指向lib/python2.7/site-packages的新環境。
