调用“createsuperuser”时引发 UnicodeEncodeError

Question

我正在尝试使用 PostGreSQL 数据库在我的服务器上部署我的 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'，然后我无法使用命令 '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)

我在谷歌上找到添加：

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

在文件的顶部，但它不起作用，结果与变量 DEFAULT_CHARSET ( https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-DEFAULT_CHARSET ) 相同。我的 PostGreSQL 数据库要求使用 utf-8 编码。

这可能是由于用于 stdin 的编码不支持在input()提示符下键入的字符这一事实造成的。

在运行命令之前，您可以尝试将编码显式设置为UTF-8使用PYTHONIOENCODING环境变量createsuperuser：

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