Question

我在7号窗口，python 2.7.2，pandas 0.11.0，django 1.4，wsgi和apache 2.2。我有一个pandas脚本，如果我直接使用python运行它也可以工作，并且也可以在ipython中运行％run。但是，当我在我的视图中运行pandas时，我得到“LookupError：unknown encoding：cp0”。只有在视图中的pandas中使用ols时才会发生这种情况。我也有点困惑为什么py3compat.py正在进入图片，因为我正在使用python 2.7。另外，我已经看到一些关于在str（）中包装打印变量的帖子，但我不确定这将如何适用于此。整个追溯是：

LookupError: unknown encoding: cp0

非常感谢！

Answer 1

关闭Spyder。

打开Anaconda Prompt并输入：set PYTHONIOENCODING = UTF-8。或者，创建一个名为“PYTHONIOENCODING”且值为“UTF-8”的环境变量。

输入spyder重新开始。

Answer 2

我也遇到了这个问题，并且使用了很多方法。但是我也失败了，但是，当我重新启动Spyder并重新运行我的程序时，这个问题已经解决了，这太棒了，我建议你可以试试这个意思

Answer 3

我也使用spyder遇到了这个问题但是当我打开一个新的控制台时，它再次运行起来很容易解决。

LookupError：未知编码：cp0
