Python 2.7 极其持久的错误

Question

我有这个模块

import os
import sys

sys.path.append("C:\pysec-master")

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "pysec-master.settings")

from pysec.models import *

"""get a file from the index. it may or may not be present on our hard disk. if it's not, it will be downloaded
the first time we try to access it, or you can call .download() explicitly"""
filing = Index.objects.filter(form='10-K',cik=1090872).order_by('-date')[0]

print filing.name

"""initialize XBRL parser and populate an attribute called fields with a dict of 50 common terms"""
x = latest.xbrl()

print x.fields['FiscalYear']

print x.fields

"""fetch arbitrary XBRL tags representing eiter an Instant or a Duration in time"""
print 'Tax rate', x.GetFactValue('us-gaap:EffectiveIncomeTaxRateContinuingOperations','Duration')

if x.loadYear(1): 
    """Most 10-Ks have two or three previous years contained in them for the major values. This call switches the contexts
    to the prior year (set it to 2 or 3 instead of 1 to go back further) and reloads the fundamental concepts.
    Any calls to GetFactValue will use that year's value from that point on."""

    print x.fields['FiscalYear']

    print x.fields

    print 'Tax rate', x.GetFactValue('us-gaap:EffectiveIncomeTaxRateContinuingOperations','Duration')

我现在正在尝试运行它一周，每当我按 F5 运行它时，我都会收到此错误：

如果您需要项目中的任何其他模块，请告诉我，我将编辑我的问题并将其放入。项目的原始文件是 here。

项目名为pysec-master，位于此目录：C:\pysec-master

项目的结构是这样的

C:\pysec-master(file)
|__C:\pysec-master\local_settings.py
|__C:\pysec-master\manage.py
|__C:\pysec-master\settings.py
|__C:\Python27\pysec(file)
   |__C:\pysec-master\pysec\__init__.py
   |__C:\pysec-master\pysec\example.py
   |__C:\pysec-master\pysec\models.py
   |__C:\pysec-master\pysec\xbrl.py
   |__C:\pysec-master\pysec\xbrl_fundamentals.py

我的环境变量是：

Path --> C:\Python27;C:\Python27\Scripts;C:\pysec-master

PYTHONPATH --> C:\pysec-master;C:\;

当我输入sys.path 我得到

['C:\\Python27\\Lib\\idlelib', 'C:\\pysec-master', 'C:\\pysec-master\\pysec', 

'C:\\Windows\\system32\\python27.zip', 'C:\\Python27\\DLLs', 'C:\\Python27\\lib', 

'C:\\Python27\\lib\\plat-win', 'C:\\Python27\\lib\\lib-tk', 'C:\\Python27', 

'C:\\Python27\\lib\\site-packages', 'C:\\pysec-master']

我已经检查过：

• 要符合的环境变量
• 设置DJANGO_MODULE_SETTINGS

那么问题是什么，我该如何解决？

Answer 1

您的DJANGO_SETTINGS_MODULE 环境变量设置为pysec-master.settings，这是错误的，原因有两个：

• pysec-master 不是有效的 Python 包名（不允许使用 -）。
• 如果它是一个有效的包名，它不会作为一个包被找到（即使你的PYTHONPATH 上有C:）因为它没有__init__.py

对于您的配置，DJANGO_SETTINGS_MODULE 可能应该只是 settings
