Question

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。我收到了这个错误：

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

（每次尝试启动iPython控制台时，json文件的名称都会更改。）

这似乎与matplotlib 1.5问题没有关系，我在其他地方已经看过 - 它使用的是1.4.3。

iPython（版本4.0.0）从命令行运行良好。

Mac 10.10.1（约塞米蒂）。 Spyder 2.3.7。达尔文的Python 2.7.10 64位，Qt 4.8.7，PyQt4（API v2）4.11.3

**进一步更新**

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

Answer 1

有一个类似的问题，并且能够通过创建一个安装了相同依赖项的新virtualenv来解决它。现在，Spyder正在使用PYTHONPATH指向新环境的lib/python2.7/site-packages。

Spyder不会连接到kernel / iPython控制台
