ModuleNotFoundError: No module named 'crispy'

ModuleNotFoundError: No module named 'crispy'

我想使用 crispy-forms 来制作博客,所以我尝试在我的代码中安装 crispy-forms,但它不起作用并且显示错误。

我喜欢下面,每个结果:

pip install django-crispy-forms

结果:

Requirement already satisfied: django-crispy-forms in /Users/eunwoo/PycharmProjects/PyShop/venv/lib/python3.8/site-packages (1.8.1)

pip3 install django-crispy-forms

结果:

Requirement already satisfied: django-crispy-forms in /Users/eunwoo/PycharmProjects/PyShop/venv/lib/python3.8/site-packages (1.8.1)

pip install -e git+git://github.com/maraujop/django-crispy-forms.git#egg=django-crispy-forms

结果:


Obtaining django-crispy-forms from git+git://github.com/maraujop/django-crispy-forms.git#egg=django-crispy-forms

和register.html(包括crispy.forms)

{% extends "base.html" %}
{% load crispy_forms_tags %}
{% block content %}

    <form method="POST">
        {% csrf_token %}
        <fieldset class="form-group">
            <legend class="border-bottom mb-4">Join Today Jin!</legend>
            {{ form|crispy }}
        </fieldset>
        <button class="btn btn-outline-info" type="submit">
            Sign Up

            Already Have An Account?
            <a href="#" class="ml-2">SIGN IN</a>
        </small>
    </div>

</div>
{% endblock content %}

那么我需要执行什么命令?

您应该在 INSTALLED_APPS 中使用 crispy_forms,而不是 cripsy.forms
