问题描述

尝试通过主管运行 gunicorn 脚本时出错。gunicorn 脚本在直接运行时运行良好。我在 ubuntu 16.04 主管版本:获取

pkg_resources.DistributionNotFound: The 'supervisor==3.2.0' distribution was not found and is required by the application

在跑步的时候

sudo supervisorctl reread

我运行 Django 应用程序的 gunicron 脚本:

#!/bin/bash

NAME="applicant_screening"                                  # Name of the application
DJANGODIR=/home/applicant-screening-system/screening_backend             # Django project directory
#SOCKFILE=/home/track_ip/run/gunicorn.sock  # we will communicte using this unix socket
USER=root                                        # the user to run as
#GROUP=webapps                                     # the group to run as
NUM_WORKERS=3                                     # how many worker processes should Gunicorn spawn
DJANGO_SETTINGS_MODULE=screening_backend.settings             # which settings file should Django use
DJANGO_WSGI_MODULE=screening_backend.wsgi                     # WSGI module name

echo "Starting $NAME as `whoami`"

# Activate the virtual environment
cd $DJANGODIR
source /home/screen-env/bin/activate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH

# Create the run directory if it doesn't exist
RUNDIR=$(dirname $SOCKFILE)
test -d $RUNDIR || mkdir -p $RUNDIR

# Start your Django Unicorn
# Programs meant to be run under supervisor should not daemonize themselves (do not use --daemon)
exec gunicorn ${DJANGO_WSGI_MODULE}:application \
  --name $NAME \
  --workers $NUM_WORKERS \
  --user=$USER \
  --bind=0.0.0.0:8000 \
  --log-level=debug \
  --log-file=-

解决方案


这是supervisor的要求和安装的python版本不匹配。为此,您需要:

  1. 安装 Python 2.7。(由于 supervisor 支持 2.* 并且对 3.* 的支持仍在开发中) https://askubuntu.com/a/981279

  2. 转到 /usr/bin/supervisorctl 文件。

  3. 将第一行更新为

!/usr/bin/python2

让主管使用安装的 python 2.7 而不是 python3。

Supervisorctl 更新文件

  1. 重新运行 supervisorctl 命令。
