没有名为 rest_framework 的模块答案

【问题标题】：No module named rest_framework没有名为 rest_framework 的模块

【问题描述】：

我在这里看到很多人遇到这个问题，我总是看到他们说其他使用 pip3 或只是 pip 安装它。

但在我的情况下，我已经使用 pip 或 pip3 多次卸载并安装了 id ，但它们似乎都不起作用。

我也在我的设置中添加了“rest_framework”，但似乎仍然无法正常工作。请帮帮我

EDIT
Here is my settings

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'agenda.apps.AgendaConfig',
    'rest_framework',

]

REST_FRAMEWORK = {
    # Use Django's standard `django.contrib.auth` permissions,
    # or allow read-only access for unauthenticated users.
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'
    ]
}

还是不行

【问题讨论】：

贴出你的代码，你用的是virtualenv吗？
如果您使用的是 virtualenv，请使用 source <virtualEnvName>/bin/activate 激活环境
如果您使用的是虚拟环境 (VE)，它将有自己的工具来安装您可以在 VE 中看到的模块。您可能正在使用 VE，甚至没有意识到它，这取决于您安装的内容。
你试过pip install djangorestframework吗？我只问是因为它是 pip install 与 import 不匹配的软件包之一。
@guillermochamorro 我没有使用 virtualenv INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions' , 'django.contrib.messages', 'django.contrib.staticfiles', 'agenda.apps.AgendaConfig', 'rest_framework', ] REST_FRAMEWORK = { # 使用 Django 的标准 django.contrib.auth 权限，# 或允许只读访问未经身份验证的用户。 'DEFAULT_PERMISSION_CLASSES'：['rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'] }

【解决方案1】：

尝试使用sudo pip install djangorestframework，我看到了其他 SO 问题，它似乎解决了问题。

【解决方案2】：

在 settings.py 文件中已安装的应用程序中，在 agenda.apps.AgendaConfig 之前添加 rest_framework。似乎agenda app 在初始化之前使用了一些 rest_framework 库。

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'rest_framework',
    'agenda.apps.AgendaConfig',


]

这个答案假设你已经成功安装了rest_framework并激活了virtualenv
