我正在开发一些 django 应用程序，但仍然很菜鸟。想使用脆皮形式，但 Eclipse 和 django 无法识别它。
尝试运行服务器或 shell：
$ python manage.py runserver
有时候是这样的：
Traceback (most recent call last):
File "manage.py", line 10, in <module>
execute_from_command_line(sys.argv)
File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 385, in execute_from_command_line
utility.execute()
File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 354, in execute
django.setup()
File "/usr/local/lib/python2.7/dist-packages/django/__init__.py", line 21, in setup
apps.populate(settings.INSTALLED_APPS)
File "/usr/local/lib/python2.7/dist-packages/django/apps/registry.py", line 85, in populate
app_config = AppConfig.create(entry)
File "/usr/local/lib/python2.7/dist-packages/django/apps/config.py", line 87, in create
module = import_module(entry)
File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
__import__(name)
ImportError: No module named crispy-forms
这是我最近与views.py一起添加到站点文件夹中的forms.py，它抱怨crispy_forms的导入未解决...：
from django.contrib.auth.forms import UserCreationForm
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout, ButtonHolder, Submit
from wx.lib.pubsub.core import kwargs
class RegistrationForm(UserCreationForm):
def __init__(self, *args, **kwargs):
super(RegistrationForm, self).__init__(*args, **kwargs)
self.helper = FormHelper()
self.helper.layout = Layout(
'username',
'password1',
'password2',
ButtonHolder(
Submit('register',
'Register',
css_class='btn-prima'
)
)
)
这是我的 settings.py 的一部分：
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'polls',
'crispy-forms',
)
...
CRISPY_TEMPLATE_PACK = 'bootstrap'
我正在运行 virtualenv，我的 venv-dir 看起来像这样：
venv/bin$ ls -la
total 2916

我无意中输入了：
pip 安装 python
今天，似乎确实如此。这会对它有什么影响吗？我的意思是，确保不存在软件冲突不是 virtualenv 的任务吗？
不管怎样，在我弄清楚这一点之前，我现在无法进行任何 Django 工作，有什么帮助吗？

更新 2：安装新的 django-project、新的 virtualenv、所有新的..同样的事情发生
(abc)nr1@kali:~/workspace/websites/abc$ pip install django-crispy-forms
收集 django-crispy-forms
使用缓存的 django-crispy-forms-1.4.0.tar.gz
安装收集的包：django-crispy-forms
为 django-crispy-forms 运行 setup.py install
成功安装django-crispy-forms-1.4.0

我现在尝试将 Crispy_forms 安装到一个完整的项目中，查看我的 virtualenv，我看到它在那里：
nr1@kali:~/Envs/abc/local/lib/python2.7/site-packages$ ls -la

所以，很清楚了。 Django 甚至不知道它安装了它。怎么可能？？ virtualenv 说它在那里，但 django 看不到它？？？哇...
