I am getting 500 Internal Server Error when I migrated my django app from
python2.7 to python3.6. I have created a new virtualenv, and created all
the apps individually. The virtualenv is defined in uwsgi.ini file
home = /home/netadc/.venvs1/netadc
I have installed all the packages using pip3.6. I am not sure what I am
missing. Every config in uwsgi is same as python2.7 when it was working.I
am using uwsgi 2.0.13. I have restarted nginx as well. Is there a separate
uwsgi for python3 which I cannot locate? The socket permissions are also
same as before. Please help.
The command to start wsgi is :- /home/netadc/.venvs1/netadc/bin/uwsgi
--ini /home/netadc/apps/netadc/netadc/uwsgi/netadc_uwsgi.ini --enable-
threads
In wsgi logs, i see :- --- no python application found, check your startup
logs for errors ---
[pid: 13634|app: -1|req: -1/3] x.x.x.x () {42 vars in 1029 bytes} [Mon Dec
17 09:04:40 2018] GET /netadc/home => generated 21 bytes in 0 msecs
(HTTP/1.1 500)
The access logs in nginx show :- x.x.x.x - - [17/Dec/2018:09:05:43 -0700]
"GET /netadc/home HTTP/1.1" 500 32
Nothing comes up in nginx error logs.
When I do manage.py shell, I see :- ImportError: bad magic number in
'lib': b'\x03\xf3\r\n'
I removed all the .pyc files, but then sometimes manage.py shell hangs up
and sometimes it opens fine. But again after sometime, I will get the
magic number error as above.
When I revert the virtualenv back to my previous virtualenv in the
uwsgi.ini file which uses python2.7, I get some error logs on uwsgi.
home = /home/netadc/.venvs/netadc Log :- File
"./ivpn/rest_appviewx.py", line 29
print('Server IP has NAT already. So no QIP update needed.', end=' ')
