无法使用 Django 启动主管

Question

我有一个 Django 应用程序，我使用 Celery 来运行后台任务。 我正在使用主管将 celery 作为服务运行，但是当我运行时：sudo supervisorctl reread，它给了我以下错误：

Traceback (most recent call last):
File "/home/user/.local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 578, in _build_master
ws.require(__requires__)
File "/home/user/.local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 895, in require
needed = self.resolve(parse_requirements(requirements))
File "/home/user/.local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 786, in resolve
raise VersionConflict(dist, req).with_context(dependent_req)
 pkg_resources.VersionConflict: (supervisor 4.0.0.dev0 (/home/user/.local/lib/python3.6/site-packages), 
  Requirement.parse('supervisor==3.3.1'))

During handling of the above exception, another exception occurred:

用supervisiord配置文件更新：-

supervisord.conf：

; supervisor config file

[unix_http_server]
file=/var/run/supervisor.sock   ; (the path to the socket file)
 chmod=0700                       ; sockef file mode (default 0700)

 [supervisord]
 logfile=/var/log/supervisor/supervisord.log ; (main log 
  file;default 
   $CWD/supervisord.log)
  pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default 
 supervisord.pid)
 childlogdir=/var/log/supervisor            ; ('AUTO' child log dir, default $TEMP)

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = 
supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL  for a 
unix socket

; The [include] section can just contain the "files" setting.  This
; setting can list multiple files (separated by whitespace or
; newlines).  It can also contain wildcards.  The filenames are
; interpreted as relative to this file.  Included files *cannot*
; include files themselves.

[include]
files = /etc/supervisor/conf.d/*.conf

Celery 配置文件：

celery_proj_worker.conf

; ==================================
; celery worker supervisor example
; ==================================
; the name of your supervisord program
 [program:proj_worker]
; Set full path to celery program if using virtualenv

; If supervisord is run as the root user, switch users to this UNIX 
 user account before doing any processing.
user=me

 ; If true, this program will start automatically when supervisord is 
 started
  autostart=true
 ; May be one of false, unexpected, or true. If false, the process will never be autorestarted. If unexpected, the process will be restart when the program exits with an exit code that is not one of the exit codes associated with this process’ configuration (see exitcodes). If true, the process will be unconditionally restarted when it exits, without regard to its exit code.
  autorestart=true
  ; The total number of seconds which the program needs to stay running after a startup to consider the start successful.
 startsecs=10
 ; Need to wait for currently executing tasks to finish at shutdown. ; Increase this if you have very long running tasks.
 stopwaitsecs = 600 
 ; When resorting to send SIGKILL to the program to terminate it ; send SIGKILL to its whole process group instead, taking care of its children as well.
 killasgroup=true
 ; if your broker is supervised, set its priority higher so it starts first
priority=998

欢迎提出任何建议。 提前致谢。

基于supervisor documents，它在任何版本的Python 3下都不能工作。
