仅限 Scrapyd - 没有模块名称 django_project.settings

Question

这个错误只发生在命令 scrapyd-deploy.

Packing version r240-master
Deploying to project "foo_bot" in http://localhost:6802/addversion.json
Server response (200):

我使用virtualenv在activate脚本末尾设置环境变量PYTHONPATH和DJANGO_SETTINGS_MODULE如下：

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

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

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

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

我运行 scrapyd-deploy development -p foo_bot 与用户 dev 和 virutalenv dev_venv.

它returns错误如上。

scrapyd 在 /home/dev/workspace/ 使用用户 dev 和端口 6802

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.

我该如何解决这个问题？我已经看到了所有线程，我不知道为什么 dev 用户失败但 deploy 用户工作。

好的，我知道了。这是因为 os.path.dirname() 会让我空路径。

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 = '/'.join([os.path.expanduser('~'), 'workspace'])
FALSE_BASE_DIR = '/'.join([WORKSPACE_DIR, 'fufu'])
BOT_NAME = 'foo_bot'
