Question

我正在尝试使用PostGreSQL数据库在服务器上部署Django应用程序（2.1.5和Python 3.6.6）。我像往常一样执行了“ makemigrations”和“ migrate”，然后无法使用命令“ createsuperuser”创建超级用户：

[alex@web574 myproject]$ python3.6 manage.py createsuperuser
Nom d'utilisateur (leave blank to use 'alex'): 
Traceback (most recent call last):

    input_value = self.get_input_data(field, message)

    raw_value = input(message)
UnicodeEncodeError: 'ascii' codec can't encode character '\xe9' in position 8: ordinal not in range(128)

我在Google上发现要添加：

# -*- Coding: utf-8 -*-

位于文件顶部，但不起作用，结果与变量DEFAULT_CHARSET（https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-DEFAULT_CHARSET）相同。我的PostGreSQL数据库要求utf-8编码。

Answer 1

这可能是由于标准输入法所使用的编码不支持在input()提示符下键入的字符引起的。

在运行UTF-8命令之前，您可以尝试使用PYTHONIOENCODING环境变量将编码明确设置为createsuperuser：

export PYTHONIOENCODING="UTF-8"; python3.6 manage.py createsuperuser

Answer 2

我认为这是与这里相同的问题： previous post 您必须添加

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

在每个文件的开头

包含正确的编码

调用'createsuperuser'时引发UnicodeEncodeError
