折腾：
【未解决】Django后台管理页面样式错乱
期间，去尝试运行：
python3 manage.py collectstatic --settings=conf.production.settings
去生成static的文件，结果出错：
[root@x-general-01 xx]# python3 manage.py collectstatic --settings=conf.production.settings Traceback (most recent call last): File "manage.py", line 8, in <module> from django.core.management import execute_from_command_line ModuleNotFoundError: No module named 'django' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "manage.py", line 14, in <module> ) from exc 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?
结果出错。
貌似没有进入虚拟环境？
之前管理应用用的是：
supervisorctl restart gunicorn
所以去看看：
[root@x-general-01 xx]# supervisorctl status gunicorn RUNNING pid 16353, uptime 1 day, 0:41:14 redis RUNNING pid 21685, uptime 29 days, 5:13:56 robotDemo RUNNING pid 21683, uptime 29 days, 5:13:56 robotDemo_CeleryBeat RUNNING pid 21684, uptime 29 days, 5:13:56 robotDemo_CeleryWorker RUNNING pid 21687, uptime 29 days, 5:13:56 [root@x-general-01 x]# supervisorctl status gunicorn gunicorn RUNNING pid 16353, uptime 1 day, 0:42:42
很明显是：
此处的supervisor管理的app的名字叫做：gunicorn（很弱智的起名，应该改为当前程序的名字x或xx或xxx）
然后要去看看supervisor的gunicorn配置是啥，然后再去看看是否用到了虚拟环境
supervisor 配置文件
找到了是：
[root@x-general-01 x]# cat /etc/supervisord.d/gunicorn.conf [program:gunicorn] directory=/root/xxx/web/server/x/ command=gunicorn --workers 4 --bind unix:/root/x/web/server/xServer.sock xServer.wsgi autostart=false autorestart=false stdout_logfile=/root/x/web/server/x/gunicorn.out.log stderr_logfile=/root/x/web/server/xx/gunicorn.err.log user=root group=root
但是还是没看到python用的是哪个版本，是系统的python3还是虚拟环境的？
再去找：
xx.wsgi
发现是：
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "conf.production.settings")
application = get_wsgi_application()
也没什么特殊的，没有找到哪里设置了python解析器的版本
然后重新安装试试：

也没有变化，之前都安装过了。
那为何：
python3 运行还会报错呢？
python3 manage.py ImportError: Couldn’t import Django
ImportError: Couldn’t import Django – Stack Overflow
推荐用虚拟环境
但是此处暂时不想去用，因为之前就没用，懒得去加

Can only get “manage.py runserver” if I use python3 instead of python – Google Groups
