Spyder将无法连接到内核/ iPython控制台

由于昨晚我的笔记本电脑崩溃（原因不明），Spyder无法连接到内核。我得到这个错误：（JSON文件的名称每次我试图启动一个IPython的控制台时间变化）Spyder将无法连接到内核/ iPython控制台

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

这似乎并没有被相关matplotlib 1.5的问题，即我在这里看过其他地方 - 它使用1.4.3。

iPython（版本4.0.0）从命令行运行正常。

Mac 10.10.1（优胜美地）。 Spyder 2.3.7。 Python的64位2.7.10，QT 4.8.7 4.11.3达尔文

更新，包括日志

**进一步更新**

我删除，PyQt4的（API第2版）我用户目录中.spyder2 /文件夹下的所有文件，重新打开Spyder，并且它能够连接到iPython控制台。到现在为止还挺好。麻烦的是，当我添加一个路径到PYTHONPATH管理器（所以我可以导入外部模块，如nltk）时，我又回到了同样的错误。

追加一些日志到你的问题会很好。 – diegoperini

我有完全相同的问题。我试图让Spyder使用带有nltk的virtualenv，并获得相同的错误。删除'.spyder2 /'并不是真正的解决方案，因为它会重置所有Spyder设置，并且您又回到使用默认解释器。你有没有在这方面取得进展？ – silentser

@silentser - 我无法想象它。这个问题发生在我直接安装的Spyder中。我最终在安装过程中安装了Anaconda并使用Spyder。现在不需要添加路径到PYTHONPATH管理器，所以它工作正常。但是为什么另一个Spyder停止了这样的工作，我仍然不知所措。祝你好运。 –

有类似的问题，并能够通过创建一个新的virtualenv与安装相同的依赖关系解决它。现在Spyder正在与PYTHONPATH合作指向lib/python2.7/site-packages的新环境。
