【问题描述】：

我正在尝试借助 tutorial 将我的第一个应用程序部署到数字海洋。

当我尝试运行 sudo supervisorctl restart [appname] 时，我收到以下错误。（这只是部分错误）

     [2019-01-16 09:10:49 +0000] [2653] [ERROR] Exception in worker process

    return _bootstrap._gcd_import(name[level:], package, level)
ModuleNotFoundError: No module named 'authSection'

我在服务器中的设置是

和主管配置文件

#!/bin/sh
[program:productUploader]
command=/home/srimal/django_project/bin/gunicorn_start
user=srimal
autostart=true
autorestart=true
redirect_stderr=true
stdout_logfile=/home/srimal/logs/gunicorn-error.log

还有 gunicorn_start 文件

#!/bin/bash

NAME="productUploader"
DIR=/home/srimal/django_project
USER=srimal
GROUP=srimal
WORKERS=3
BIND=unix:/home/srimal/run/gunicorn.sock
DJANGO_SETTINGS_MODULE=productUploader.shadesProductUploader.settings
DJANGO_WSGI_MODULE=productUploader.shadesProductUploader.wsgi
LOG_LEVEL=error

cd $DIR
source /home/srimal/django_project/bin/activate

export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DIR:$PYTHONPATH

exec /home/srimal/django_project/bin/gunicorn    ${DJANGO_WSGI_MODULE}:application \
 --name $NAME \
 --workers $WORKERS \
 --user=$USER \
 --group=$GROUP \
 --bind=$BIND \
 --log-level=$LOG_LEVEL \
 --log-file=-

我做错了什么？

【问题讨论】：

发布您的 productUploader.shadesProductUploader.settings 文件，您可能错过了安装依赖项或将其添加到 INSTALLED_APPS。
setting.py 文件位于 shadesProductUploader 文件夹下。我将只添加已安装的应用程序部分，因为完整的文件对于 stackoverflow 来说太长了。
INSTALLED_APPS = ['authSection'，'mainSection'，'django.contrib.humanize'，'django.contrib.admin'，'django.contrib.auth'，'django.contrib.contenttypes' , 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ]
productUploader 文件夹是否包含__init__.py？

【解决方案1】：

看起来productUploader 目录似乎是一个python 包，这是基于您在DJANGO_SETTINGS_MODULE 和DJANGO_WSGI_MODULE 的虚线路径中传递它的事实。因此，您也应该对INSTALLED_APPS 中的应用程序执行相同操作：

INSTALLED_APPS = [
    'productUploader.authSection',  # Use full path
    'productUploader.mainSection',  # Use full path
    'django.contrib.humanize',
    'django.contrib.admin', 
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles',
]
