Question

我收到一个错误，ModuleNotFoundError: No module named ‘rest_framework’ when I run command python manage.py runserver 。回溯说

ModuleNotFoundError: No module named 'rest_framework'

我已经运行命令 pip3 install djangorestframework ，当我再次运行这个命令时，要求已经满足：/usr/local/lib/python3.6/site-packages 中的 djangorestframework 显示在终端中。Python 版本是 3.6.2。我的代码有什么问题？我应该如何解决这个问题？我使用 Anaconda 虚拟环境。

Answer 1

您是否在设置中添加了 rest_framework？

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

也许这篇 文章 会对你有所帮助。看一看。

Answer 2

看起来好像 pip3 install 已经将包安装到 /usr/local/lib/python3.6/site-packages ，而不是你的环境 /Users/xxx/anaconda/envs/env/lib/python3.6/site-packages 。

如果您使用 python -m pip ，那么该包将安装在您运行 python manage.py runserver 时使用的同一版本的 python 中。这是 Python 文档 中建议的命令。

 python -m pip install djangorestframework
