python - 模块未找到错误 : No module named 'rest_framework' I already installed djangorestframework

Question

我收到一个错误，ModuleNotFoundError: No module named 'rest_framework' 当我运行命令 python manage.py runserver 时。回溯说

我已经运行命令pip3 install djangorestframework，当我再次运行这个命令时，Requirement already satisfied: djangorestframework in/usr/local/lib/python3.6/site-packages shows in terminal.Python版本是 3.6.2。我的代码有什么问题？我该如何解决？我使用的是 Anaconda 虚拟环境。

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，则该包将安装在您运行 python manage.py runserver 时使用的同一版本的 python 中。这是建议的命令 in the Python docs .

python -m pip install djangorestframework
