No module named import_export although it is installed

Question

I'm trying to use django-import-export in my django site. I installed it in my virtual environment using "pip install django-import-export" and I know it's there because I ran pip freeze but it still gives an error when I do "eb create django-env": "ModuleNotFoundError: No module named 'import_export'".

It is included in INSTALLED_APPS in settings.py and I ran "python manage.py collectstatic" before I got the error.

2019-05-26 06:21:41    ERROR   [Instance: i-08f7c48c9afd84a8f] Command failed on instance. Return code: 1 Output: (TRUNCATED)...ile "<frozen importlib._bootstrap>", line 994, in _gcd_import

I am a beginner and this is my first question on StackOverflow. I appreciate any help.

Answer 1

也许您没有成功安装django-import-export。尝试检查您的虚拟环境。

Answer 2

I think I understand what I did wrong before. I checked the requirements.txt file in my environment and it didn't mention django-import-export.

"Elastic Beanstalk uses requirements.txt to determine which package to install on the EC2 instances that run your application."

So I did pip freeze > requirements.txt, then checked to make sure that the requirements.txt file was updated. After that the deployment worked and I can now see the import button in the admin!
