部署Scrapy时发生ValueError [英] ValueError while deploying Scrapy

问题描述

我正在尝试使用 scrapyd-deploy 命令部署Scrapy，现在它会引发下一个错误：

I am trying to deploy Scrapy with scrapyd-deploy command and now it throws next error:

    "status": "error"}

first_scrapy中的第24行和第25行。设置为：

Line 24 and 25 in first_scrapy.settings are:

import django
django.setup()

这是 my_project.settings.LOGGING ：

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'file': {
            'level': 'WARNING',
            'class': 'logging.FileHandler',
            'filename': os.path.join(BASE_DIR, 'debug.log'),
        },
        'mail_admins': {
              'level': 'ERROR',
              'class': 'django.utils.log.AdminEmailHandler'
        },
    },
    'loggers': {
        'django': {
            'handlers': ['file'],
            'level': 'WARNING',
            'propagate': True,
        },
    },
}

和 BASE_DIR = os.path.dirname（os.path.dirname（os.path。 abspath（__ file __）））


由于我无法理解 settings.LOGGING 中有什么问题，但是我可以不能得到什么。您能帮我吗？

这不是重复的。这是类似的问题，但是我有不同的原因导致此错误-我没有创建。我已经检查了该问题上显示的所有内容-并且可以在本地服务器上使用。

And BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

As I unserstand something is wrong in settings.LOGGING but I can't get what. Can you help me?
This is not duplicate. That is the similar question, but I have different reasons of this error - I don't create.I have checked everything as it is shown on that question - and it works on local sever.

推荐答案

由于 BASE_DIR 是从草率方面声明和使用的，因此您在该设置文件中设置的所有内容的形式为：

As BASE_DIR is declared and used from scrapy side, everything you set inside that settings file in the form of:

os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

将引用scrapy工作的路径，在错误中显示为：

would make reference to the path where scrapy works, shown in the error as:

/tmp/first_scrapy-1526919848-13w8cqlm.egg

因此最好在设置文件中定义自己的 LOG_DIR ，而不使用当前路径，在一个已知文件夹中，您可以使用：

So better define your own LOG_DIR in the settings file, not using the current path, in a know folder you can use:

LOG_DIR = '/path/to/logs/'

'filename': os.path.join(LOG_DIR, 'debug.log')

或者在项目的其他文件中设置环境变量（也许在Django中）轻松从设置文件中获取：

Or, set an environment variable in other file of your project (maybe in django) easily to grab from settings file:

任何其他 .py 文件：

import os
os.environ['LOG_DIR'] = '/path/to/log/'

在 settings.py 文件中：

LOG_DIR=os.environ['LOG_DIR']

'filename': os.path.join(LOG_DIR, 'debug.log')

也您可以登录 / tmp 使用相对路径，如下所示：

Also you could log to /tmp using the relative path, as follows:

'filename': os.path.join(BASE_DIR, '..', 'debug.log')
