解决django项目报错很离谱的报错之RuntimeError: populate() isn't reentrant

 

 

1.看到这个报错是不是很懵逼

2.去修改这个文件

/usr/local/lib/python3.6/site-packages/django/apps/registry.py

 

3.到最后面发现是包安装的不够 就会报错

celery==5.0.5
mongoengine==0.22.1
djangorestframework==3.12.2
django-cors-headers==3.7.0

yum install python3-devel gcc -y

pip3 install mysqlclient==2.1.1
