从3移植到2.7:ImportError:无法导入名称

[英]Backporting from 3 to 2.7: ImportError: cannot import name

After reading this , and crying a lot, I'm trying to make my Django app work with Python 2.7. 看完这篇文章 ,哭了很多之后,我试图使我的Django应用程序与Python 2.7一起使用。

Here's my Django web dir: 这是我的Django网站目录:

├── locale
│   ├── en
│   ├── fr
│   └── sv
├── produits
│   ├── migrations
│   └── templatetags
├── pyweb
├── templates
│   └── produits
├── third_party
│   ├── authomatic_0_1_0
│   ├── defusedxml-0.4.1
│   ├── google_appengine_1_9_25
│   ├── python-openid_2_2_5
│   └── python3-openid
└── uploads

The most important to notice is that I've tried to add all my "external" module into a folder third_party . 需要注意的最重要的一点是,我尝试将所有“外部”模块添加到文件夹third_party

In my views.py , the following code was working: 在我的views.py ,以下代码正在工作:

from third_party.authomatic_0_1_0 import authomatic
from third_party.authomatic_0_1_0.authomatic import adapters
from third_party.authomatic_0_1_0.authomatic.providers import oauth1, oauth2

It was working because I added those lines in settings.py at the very beginning: 之所以起作用,是因为我一开始就在settings.py添加了这些行

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(BASE_DIR+'/third_party/defusedxml-0.4.1')
sys.path.append(BASE_DIR+'/third_party/python3-openid')
sys.path.append(BASE_DIR+'/third_party/google_appengine_1_9_25')
sys.path.append(BASE_DIR+'/third_party/authomatic_0_1_0')

But now, with python 2.7 it doesnt work anymore. 但是现在,在python 2.7中它不再起作用了。 What should I do to make it work? 我应该怎么做才能使其正常工作? And what is a good practice in Python (because Pycharm doesn't recognize all the subfolders of third_party )? 在Python中有什么好的做法(因为Pycharm不能识别third_party所有子文件夹)?

Two problems: (1) encoding, so I added in all files at the very beginning: 两个问题:(1)编码,因此我在一开始就添加了所有文件:

# coding=UTF-8

(2) Decorator python_2_unicode_compatible : needed this for all my models with __str__ implemented, for example: (2)Decorator python_2_unicode_compatible :我实现了__str__所有模型都需要装饰器,例如:

@python_2_unicode_compatible
class Texte(models.Model):
    texte = models.CharField(max_length=200)

    def __str__(self):
        return self.texte
