Question

我有一个django项目，带着gunicorn。我有以下gunicorn_start：

#! /bin/bash

NAME="ostabs2"
DJANGODIR=/srv/osmium/ostabs2
SOCKFILE=/srv/osmium/run/gunicorn.sock
USER=tabuser
GROUP=webapps
NUM_WORKERS=3
DJANGO_SETTINGS_MODULE=ostabs2.settings
DANGO_WSGI_MODULE=ostabs2.wsgi

echo "Starting $NAME as 'whoami'"

cd $DJANGODIR
source /srv/osmium/venv/bin/activate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH

exec gunicorn ${DJANGO_WSGI_MODULE}:application \
  --preload \
  --name $NAME \
  --workers $NUM_WORKERS \
  --user=$USER --group=$GROUP \
  --log-level=debug \
  --bind=unix:$SOCKFILE \
  --log-file=ostabsgun.log

运行

gunicorn ostabs2.wsgi:application

命令行上的

工作正常，但gunicorn_start脚本给出：

Traceback (most recent call last):
  File "/srv/osmium/venv/bin/gunicorn", line 11, in <module>
    sys.exit(run())
  File "/srv/osmium/venv/local/lib/python2.7/site-packages/gunicorn/app/wsgiapp.py", line 74, in run

    self.app.wsgi()

    return self.load_wsgiapp()
  File "/srv/osmium/venv/local/lib/python2.7/site-packages/gunicorn/app/wsgiapp.py", line 52, in load_wsgiapp
    return util.import_app(self.app_uri)
  File "/srv/osmium/venv/local/lib/python2.7/site-packages/gunicorn/util.py", line 356, in import_app
    __import__(module)
ValueError: Empty module name

什么会导致此错误？项目中是否存在错误，或者缺少依赖项？我检查了所有文件和目录的用户权限，tabuser具有完全的读/写访问权限。如何找出导致此问题的原因？

更新：我已经按照this问题的建议，数据库定义是正确的（我可以在本地和服务器上运行syyncdb）。安装的应用程序部分中没有空字符串，我已将整个应用程序中的引用删除到不再使用的库中还有什么可以导致这个错误吗？

使用--preload运行gunicrn_start.sh：错误清空模块名称
