这是我的wsgi 文件

#!/usr/bin/python3
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/dj/")

from dj import app as application
application.secret_key = 'SECERET'

这是我的项目结构-

--var
---www
----dj(folder)
-----dj(folder) , dj.wsgi
------- __init__.py, static...

pip freeze 是否在已安装的软件包中返回 flask_login？ 您的日志显示找不到 flask_login 模块。
