本文主要是介绍(20210129已解决)SyntaxError: Non-ASCII character ‘\xe6‘ in file filename.py , but no encoding decla，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

• Overview

  如题，运行程序出现上述提示。

• 原因解析

  这个问题经常是出现在crontab设置运行python时。

  同样的程序，在IDE中直接运行是正常的。

  The reason why it works differently in console and in the IDE is, likely, because of different default encoding set. You can check it by running:L

  import sys
  print(sys.getdefaultencoding())
  

  The default for Python2 is ASCII, while Python3 utf-8.

• 解决方案

  Add this code for encoding at the just begin of the code source:

  # -*- coding: utf-8 -*-
