Question

我安装了bootstrap4

$ pip install django-bootstrap4

它正在安装在此目录中

C:\Users\trade\techpit-match-env\Lib\site-packages

Django似乎正在查看此目录

C:\Users\trade\Anaconda3\lib\site-packages\django

当我将'bootstrap4'放入INSTALLED_APPS =（'bootstrap4'）变量然后运行时

$ python manage.py runserver

我收到此错误

C:\Users\trade\techpit-match-env\Scripts\techpit>python manage.py runserver

ModuleNotFoundError: No module named 'bootstrap4'

如何解决此错误？我通过使用复制和粘贴在django文件夹中安装了bootstrap4，但这没有用。任何帮助将不胜感激。

谢谢！

Answer 1

python -m pip install bootstrap4

这会将pip定位在python模块路径上，从而确保将bootstrap4安装在用于运行manage.py命令的同一python环境中。参见this。

Answer 2

我在做同样的课程，我得到了答案。通过我检查的步骤：

适当的虚拟环境
适当的库
检查 lib 文档

我发现了一些有趣的东西。这是已安装的应用程序密钥 INSTALLED_APPS 的顺序。

此配置键无效：

    INSTALLED_APPS = [
    # own applications
    'learning_logs',
    'users',
    # 3 party applications
    'bootstrap4'
    # django framework applications
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

但是这项工作

INSTALLED_APPS = [
    # own applications
    'learning_logs',
    'users',
    # django framework applications
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # 3 party applications
    'bootstrap4'
]

将 'bootstrap4' 移到最后修复加载此库。

问候，马辛

Answer 3

在 settings.py INSTALLED_APPS 中检查“bootstrap 4”后是否有逗号

应该是这样的：

INSTALLED_APPS = [
    # my apps
    'learning_logs',
    'users',
    # outside apps
    'bootstrap4',
    # django apps
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

ModuleNotFoundError：没有名为“ bootstrap4”的模块
