python - python manage.py dumpdata 无法序列化数据库

Question

我正在尝试运行命令 python manage.py dumpdata > data.json

但是，我收到这样的回溯：

CommandError: Unable to serialize database: 'charmap' codec can't encode characters in position 1-4: character maps to <undefined>
Exception ignored in: <generator object cursor_iter at 0x0000020E11353820>
Traceback (most recent call last):
  File "C:\Users\Illia\Desktop\MyDjangoStuff\greatkart\venv\lib\site-packages\django\db\models\sql\compiler.py", line 1625, in cursor_iter
    cursor.close()
sqlite3.ProgrammingError: Cannot operate on a closed database.

如何解决这个问题？

Answer 1

set PYTHONIOENCODING=utf-8之前运行python manage.py dumpdata > data.json已经解决了这个问题。
