ImportError: No module named crispy-forms

pythondjangodjango-crispy-forms

提问by beowwwulf

I'm working on some django apps, pretty noob still. Would like to use crispy-forms, but eclipse and django doesnt recognize it.

我正在开发一些 django 应用程序，仍然很菜。想使用脆皮形式，但 eclipse 和 django 无法识别它。

Trying to runserver or shell:

尝试运行服务器或外壳：

$ python manage.py runserver

this happens:

有时候是这样的：

This is the forms.py I recently added to the site-folder alongside views.py, and it complains about unresolved import of crispy_forms...:

这是我最近与views.py一起添加到站点文件夹中的forms.py，它抱怨未解决的crispy_forms导入...：

from django.contrib.auth.forms import UserCreationForm

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',

I accidentally managed to type in: pip install python today, and it seems it did. Could that have any impact on it? I mean, isnt it virtualenv's task to make sure there is no software-conflicts?

我今天不小心输入了：pip install python，似乎确实如此。这对它有什么影响吗？我的意思是，确保没有软件冲突不是 virtualenv 的任务吗？

Anyway, I cant get any Django-work going now until i figure this out, any help out there?

无论如何，在我弄清楚之前，我现在无法进行任何 Django 工作，有什么帮助吗？

So, its clear. Django doesn't even recognize that its installed it. How can that be?? virtualenv says its there, but django cant see it??? wtx...

所以，很清楚。Django 甚至不承认它安装了它。怎么可能？？virtualenv 说它在那里，但 django 看不到它？？？重量...

Ok, so I found by chance(almost) another post, this one: Getting stuck at Django error: No module named registration

好的，所以我偶然（几乎）找到了另一篇文章，这篇文章：陷入 Django 错误：没有名为注册的模块

and thought it might have something to do with pythonpath.

并认为它可能与pythonpath有关。

so then I tried easy_install, like suggested:

所以我尝试了easy_install，就像建议的那样：

 $ easy_install -Z django-crispy-forms
    Searching for django-crispy-forms
    Best match: django-crispy-forms 1.4.0
    Adding django-crispy-forms 1.4.0 to easy-install.pth file

    Using /home/nr1/Envs/abc/lib/python2.7/site-packages
    Processing dependencies for django-crispy-forms
    Finished processing dependencies for django-crispy-forms

Now it works! I still think there might be something missing with the pythonpath, because I keep getting this in eclipse:

现在它起作用了！我仍然认为 pythonpath 可能缺少一些东西，因为我一直在 eclipse 中得到这个：

SignUpView Found at: __module_not_in_the_pythonpath__

, and I would like someone to clarify it, so feel free to contribute here...

，我希望有人澄清它，所以请随时在这里做出贡献......

but django and crispy_forms now works together. YippikayeyMF!!

但是 django 和crispy_forms 现在可以一起工作了。YippikayeyMF！！

You have to make sure that you install crispy-forms into the virtualenv.

您必须确保将crispy-forms 安装到virtualenv 中。

  1. Activate VirtualEnv (where env is the directory/name of your virtual environment):

    source env/bin/activate

  2. Install crispy-forms

    pip install django-crispy-forms

  1. 激活 VirtualEnv（其中 env 是虚拟环境的目录/名称）：

    源环境/bin/激活

  2. 安装脆皮形式

    pip 安装 django-crispy-forms

回答by Abhishek Agarwala

As per the documentation : http://django-crispy-forms.readthedocs.org/en/latest/install.html#installing-django-crispy-forms, you have to add 'crispy_forms' not 'crispy-forms' to your Installed Apps list.

根据文档：http: //django-crispy-forms.readthedocs.org/en/latest/install.html#installing-django-crispy-forms ，您必须将“crispy_forms”而不是“crispy-forms”添加到您的已安装的应用程序列表。

I use PyCharm for my Django projects. I get exactly the same error as you but in PyCharm until I change the Python interpreter used by PyCharm for the project. I have to, for each project, select the Python interpreter that resides in the relevant virtalenv folder to get the IDE (PyCharm) to recognize the installed modules. I suspect that the Pythonpath lurks somewhere in the background...

我将 PyCharm 用于我的 Django 项目。我得到与您完全相同的错误，但在 PyCharm 中，直到我更改 PyCharm 用于项目的 Python 解释器。对于每个项目，我必须选择位于相关 virtalenv 文件夹中的 Python 解释器，以使 IDE (PyCharm) 识别已安装的模块。我怀疑 Pythonpath 潜伏在后台的某个地方...

Doesn't Eclipse allow you to select the interpreter to use for a project? That's where I'd start looking.

Eclipse 不允许您选择用于项目的解释器吗？那就是我开始寻找的地方。

Good luck!

祝你好运！

I came across the same problem and figured out an alternate way around.

我遇到了同样的问题并想出了另一种方法。

  1. Exit Virtualenv.
  2. Do a fresh pip install of crispy form at the root directory.
  3. Go back to Virtualenv and make migrations followed by migrate.
  1. 退出 Virtualenv。
  2. 在根目录中执行新的脆皮形式的 pip 安装。
  3. 返回 Virtualenv 并进行迁移，然后进行迁移。

I think the django installation needs that all third party app be installed inside and as well outside the virtual env.
I would really appreciate if someone could help me with inside details behind the reason.

我认为 django 安装需要将所有第三方应用程序安装在虚拟环境内外。
如果有人可以帮助我了解原因背后的内部细节，我将不胜感激。

回答by Johnny Camby

All the above answers are missing one thing. Please cross check the location of your 'External Libraries' on the drive first before you do any of the above advises. Reason: - You be using an IDE that points to a different python directory, that is for guys who have install python more than once.

以上所有答案都缺少一件事。在执行上述任何建议之前，请先交叉检查驱动器上“外部库”的位置。原因： - 您使用的 IDE 指向不同的 python 目录，这适用于多次安装 python 的人。

  • don't think your 'virtualenv' is pointing to the right directory were your 'External Libraries' are stored. So if you go ahead and install in a wrong directory then such error will ok
  • 不要认为您的“virtualenv”指向正确的目录，因为您的“外部库”已被存储。所以如果你继续安装在错误的目录中，那么这样的错误就可以了

回答by Toguko

I solve this problem right now, I realize that the crispy-form installed version was the python 2.7 version, but I'm using Django-1.10 with python 3.5, and I think this is your problem too.

我现在解决了这个问题，我意识到安装的版本是 python 2.7 版本，但我使用的是 Django-1.10 和 python 3.5，我认为这也是你的问题。

Try: pip3 install --user django-crispy-forms

尝试： pip3 install --user django-crispy-forms
