只有Scrapyd没有模块名Django_项目.设置

Question

此错误仅在命令scrapyd-deploy上发生。在

Packing version r240-master
Deploying to project "foo_bot" in http://localhost:6802/addversion.json

项目结构如下：

^{pr2}$

scrapy.cfg

[settings]
default = foo_bot.settings

[deploy:local]
url = http://localhost:6801/
project = foo_bot

[deploy:development]
url = http://localhost:6802/
project = foo_bot
version = GIT

[deploy:deployment]
url = http://localhost:6800/
project = foo_bot
version = GIT

foo_bot/foo_bot/settings.py

import os
import sys
import django

########## PATH CONFIGURATION
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
FALSE_BASE_DIR = os.path.dirname(BASE_DIR)
#WORKSPACE_DIR = os.path.dirname(FALSE_BASE_DIR) // fail with just scrapy crawl bar
WORKSPACE_DIR = '/'.join([os.path.expanduser('~'), 'workspace'])
BOT_NAME = 'foo_bot'
########## END PATH CONFIGURATION

########## DJANGO CONFIGURATION
DJANGO_PROJECT_PATH = '/'.join([FALSE_BASE_DIR, 'foo_project'])

try:
    from settings_dev import *
except ImportError:
    pass

import os

########## PATH CONFIGURATION
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
FALSE_BASE_DIR = os.path.dirname(BASE_DIR)
WORKSPACE_DIR = os.path.dirname(FALSE_BASE_DIR)
PROJECT_NAME = 'foo_project'
########## END PATH CONFIGURATION

foo_project/foo_project/wsgi.py

import os

from django import conf
from django.core.wsgi import get_wsgi_application

conf.ENVIRONMENT_VARIABLE = 'DJANGO_SETTINGS_MODULE'
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'foo_project.settings')

application = get_wsgi_application()

我使用virtualenv在activate脚本的末尾设置环境变量PYTHONPATH和{}，如下所示：

export PYTHONPATH="/home/dev/workspace/fufu/foo_project"
export DJANGO_SETTINGS_MODULE="foo_project.settings"

我在fufu/foo_bot运行scrapy crawl bar，它运行成功（并通过djangoitem保存到数据库）。在

我在fufu/foo_project运行django-admin.py，它运行成功，没有任何警告。在

我运行python manage.py在fufu/foo_project，它成功运行，没有警告。在

我用用户dev和virutalenvdev_venv运行scrapyd-deploy development -p foo_bot。在

它将按上述方式返回错误。在

使用用户dev和端口6802，在{}调用{}

However, I have another user deploy with a project copy at /home/deploy/workspace/fufu/ with only different on the from settings_dev to from settings_deploy and those absolute paths.

I run scrapyd-deploy deployment -p foo_bot with user deploy and virutalenv deploy_venv.

It runs perfectly.

The scrapyd is called at /home/deploy/workspace/ with user deploy and port 6800.

我怎么解决这个问题？我看过所有的线程，我不知道为什么dev用户失败，而{}用户工作正常。在

好的，我知道了。 因为os.path.dirname()会给我一条空路径。在

foo_bot/foo_bot/settings.py

########## PATH CONFIGURATION
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
#FALSE_BASE_DIR = os.path.dirname(BASE_DIR)
#WORKSPACE_DIR = os.path.dirname(FALSE_BASE_DIR) // fail with just scrapy crawl bar
WORKSPACE_DIR = '/'.join([os.path.expanduser('~'), 'workspace'])
FALSE_BASE_DIR = '/'.join([WORKSPACE_DIR, 'fufu'])
BOT_NAME = 'foo_bot'
