django项目民意调查坚持使用自己的包步骤
我是Python和Django的新手，请原谅我，如果这个问题看起来很愚蠢。我跟随django tutorial并且在您使用自己的套餐时遇到了这个步骤
应用mysite有效且没有错误。
我已根据教程设置了所有必需的文件。
我已经python3 setup.py sdist（在django-polls文件夹中）
django-polls-0.1.tar.gz
django-polls/dist/个文件
$ cd ..
$ pip3 install --user django-polls/dist/django-polls-0.1.tar.gz
Processing ./django-polls/dist/django-polls-0.1.tar.gz
Requirement already satisfied (use --upgrade to upgrade): django-polls==0.1 from file:///home/viet/webdev/django-polls/dist/django-polls-0.1.tar.gz in /home/viet/.local/lib/python3.6/site-packages
Building wheels for collected packages: django-polls

然后教程说：
幸运的是，您的Django项目现在应该再次正常工作。跑 服务器再次确认这一点。
如何？ manage.py或/django-polls
/home/viet/.cache/pip/wheels/ff/ec/8b/85c031efa2ba719d6bd909d20f61ca6b106c79345a1e875f08个文件
所以我尝试了这个：
$ pip3 uninstall django-polls
Uninstalling django-polls-0.1:

我此时已经迷失了。
更新
感谢您的建议，我现在理解我需要将文件夹/polls从我的文件夹/mysite移到文件夹/django-polls
所以树看起来像这样：
~/webdev$ ls -a
django-polls mysite
$ cd django-polls/
s$ ls -a
. dist docs MANIFEST.in README.rst
.. django_polls.egg-info LICENSE polls setup.py
我参加了/webdev：
$ pip3 install --user django-polls/dist/django-polls-0.1.tar.gz
Processing ./django-polls/dist/django-polls-0.1.tar.gz
...
Successfully built django-polls
$ cd mysite/
$ python3 manage.py migrate

The above exception was the direct cause of the following exception:

工作正常时会出现TemplateDoesNotExist错误？< / p>

新错误：

之前运行正常，我尝试在虚拟环境中启动服务器，但该应用程序无法识别已安装的Django。

答案 0 :(得分：2)
本教程packaging your app section中的第2步指示将民意调查应用程序从项目目录移至django-polls。
如果此时你运行开发服务器，django将抛出一个异常，因为polls在已安装的应用程序中列出，但在python可见的任何路径中都不存在。
安装软件包时，pip会在python安装的site-packages目录中安装django-polls软件包。
此时，运行migrate，应该使用site-packages中的民意调查应用程序。
答案 1 :(得分：1)
1）对于你问题的第一部分：我很想念，抱歉。 @Paulo和@Vishal已经很好地解释了。
2）对于第二部分：您已经成功安装了django-polls app，所以
您的服务器运行并找到polls应用，但无法找到'polls / index.html'模板。这就是为什么你看到下面的错误：
TemplateDoesNotExist: polls/index.html, polls/question_list.html
您应该检查模板文件是否在正确的位置。
如果您在虚拟环境中安装了path_to_virtualenv\Lib\site-packages\polls\templates\polls应用，则模板位于django-polls目录中。否则（系统范围的安装），您可以查看python_path\Lib\site-packages\polls\templates\polls
到目前为止，你可能已经解决了这个问题，很抱歉由于某些原因最近回答。我希望它有所帮助。
答案 2 :(得分：1)
这是我的案子出现错误：
django.template.exceptions.TemplateDoesNotExist：民意调查/index.html，民意调查/question_list.html
我遵循此指南：https://docs.djangoproject.com/en/2.2/intro/reusable-apps/
而且，我正在使用virtualenv。
这是我的文件夹结构：
(venv) ☁ mrdulin tree -L 1 | grep 'django'
├── django-codelab
├── django-polls
由MANIFEST.in文件的文件名引起的错误。我从指南中复制了文件名。但是不知何故，文件名的开头有一个空白空间。这意味着文件名是
当我运行python setup.py sdist命令时，输出如下：

现在，template，static，docs目录中的文件已复制到dist目录。
然后，将目录更改为django-codelab，运行以下命令：
pip3 install ../django-polls/dist/django-polls-0.1.tar.gz
将polls应用程序添加到INSTALLED_APPS列表中：
INSTALLED_APPS = [
'polls',
# 'polls.apps.PollsConfig',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]
运行服务器：
python manage.py runserver
它完美地工作！ 因此，本教程是正确的。请检查您的步骤，并仔细编码
答案 3 :(得分：1)
您应验证
django-民意调查
已根据您启动的命令成功安装
df = pd.read_csv('file.csv')
df['age'] = df['death'] - df['birth']
我在Windows上，如果成功，它将安装在内部
pip install --user django-polls/dist/django-polls-0.1.tar.gz
如果您只看到
C:\Users\{username}\AppData\Roaming\Python\Python37\site-packages
-->django_polls-0.1-py3.7.egg-info
-->polls
然后您应该仔细检查-->django_polls-0.1-py3.7.egg-info
是否正确（包括缩进），然后再次运行setup.cfg
如果所有操作都正确，则在提取python setup.py sdist目录的项目（以前使用过的同一项目）内，像之前（manage.py）一样运行服务器
polls（请记住）D:\websiteprojects\djangotutorial01\mysite>python manage.py runserver
文件夹不再位于该文件夹中
polls但是它仍然可以运行，因为它已成功安装在内部
