我正在运行一个django应用程序与mariadb。它以前工作得很好，但是我把这个项目闲置了一段时间，现在我刚回来，我不知道为什么它现在坏了。
当尝试运行python manage.py makemigration时，我得到以下错误:
File "manage.py", line 16
) from exc
^
SyntaxError: invalid syntax
这是我的管理。py:
#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys
def main():
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'MyDB.settings')
try:
from django.core.management import execute_from_command_line
except ImportError as exc:
raise ImportError(
"Couldn't import Django. Are you sure it's installed and "
"available on your PYTHONPATH environment variable? Did you "
"forget to activate a virtual environment?"
) from exc
execute_from_command_line(sys.argv)
if __name__ == '__main__':
main()
现在我要说实话了。我也许知道是什么问题。我不用venv。我在这个系统上安装了多个装置。问题是我不记得我在这个项目中使用了什么。我有python 2.7和python 3。Python 2.7运行Django 1.11, Python 3运行Django 2.2.7。
当我在python 3中运行manage.py时，它返回以下内容:
Traceback (most recent call last):

The above exception was the direct cause of the following exception:

Did you install mysqlclient?
现在这看起来像一个数据库错误，我。但是我以前和MariaDB一起工作的很好。我甚至按照django页面和mariadb页面上的安装指南进行了完全的卸载和重新安装。我现在真的要被这事困住了。有人能给我指个方向吗?
编辑:我已经尝试了解决方案，如安装pymysql和其他问题。但到目前为止，我似乎还没能找到答案。
尝试使用python3运行应用程序(如果您正在使用python3)。X而不是python only
