python - 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“迁移”，然后无法使用命令“createsuperuser”创建 super 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)
  File "/home/alex/webapps/global_hse_project/lib/python3.6/Django-2.1.5-py3.6.egg/django/contrib/auth/management/commands/createsuperuser.py", line 194, in get_input_data
    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，与变量 DEFAULT_CHARSET ( https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-DEFAULT_CHARSET ) 的结果相同。我的 PostGreSQL 数据库要求使用 utf-8 编码。

Answer 1

这可能是因为用于标准输入的编码不支持在 input() 提示符下输入的字符。

您可以尝试使用 PYTHONIOENCODING 将编码显式设置为 UTF-8运行 createsuperuser 命令之前的环境变量:

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