python - 查找错误 : unknown encoding: cp0

Question

我在 window 7、python 2.7.2、pandas 0.11.0、django 1.4、wsgi 和 apache 2.2 上。我有一个 pandas 脚本，如果我直接用 python 运行它就可以正常工作，也可以在 ipython 中使用 %run 运行。但是，当我在我的 View 中运行 pandas 时，我得到“LookupError:未知编码:cp0”。只有在 View 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 在我使用 python 2.7 时进入画面。另外，我看过一些关于在 str() 中包装打印变量的帖子，但我不确定这在此处如何应用。整个追溯是:

非常感谢!

关闭 Spyder。

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

键入 spyder 重新开始。
