调用“createsuperuser”时引发UnicodeEncodeError

Question

我正试图在带有PostGreSQL数据库的服务器上部署Django应用程序（2.1.5和python3.6.6）。 我不能像往常一样创建一个超级用户迁移

[alex@web574 myproject]$ python3.6 manage.py createsuperuser

我在谷歌上发现：

^{pr2}$

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utf-8编码。在

Answer 1

在运行createsuperuser命令之前，可以尝试使用^{}环境变量显式地将编码设置为UTF-8：

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